The document discusses management information systems (MIS) and provides definitions and descriptions of key concepts:
1. The objective of an MIS is to provide information to support decision making for planning, organizing, and controlling operations.
2. An MIS includes people, hardware, software, networks, and data resources that collect, process, and disseminate organizational information.
3. Information systems can support various business functions and levels of management, be classified by type of processing or usage, and are measured by their efficiency and effectiveness in supporting the organization.
Management Information Systems
The objective of an MIS is to provide information for decision making on planning, initiating,
organizing and controlling the operations of subsystems of the firm and to provide a synergistic
organization in the process.
A system is a group of interrelated or interacting elements forming a unified whole, and working
together towards a common goal by accepting inputs and producing outputs in an organized transformation
process.
Such a system has three basic (it can become more useful by including others) interacting components or
functions namely:
• Inputs
• Processing
• Output
It could also include:
• Feedback / Storage as the case may be
• Control (monitoring and evaluating feedback or information) to maintain performance
An open system interacts with other systems, whereas a closed system does not interact with other
systems. A system that has the ability to change itself or its environment in order to survive is an adaptive
system e.g. organization as a system.
Terms used in the system’s concept.
1. A system’s purpose is the reason for its existence and the reference point for measuring its
success e.g. the purpose of Dell’s order fulfillment system is to efficiently produce and deliver
what the customer ordered.
2. A system’s boundary defines what is inside the system and what is outside e.g. ordering system
might consider delivering outside its boundary.
3. A system’s environment is everything pertinent to the system that is outside of its boundaries.
4. A system’s inputs are the physical objects and information that cross the boundary to enter it
from its environment.
5. A system’s outputs are physical objects and information that go from the system into its
environment.
Work systems in businesses need to change frequently to accommodate to changing conditions in their
environments and changing customer needs.
System Analysis aims at studying the present and/or proposed information flows in order to find the
ways of meeting the objectives of the organization, in the best way possible. These ways may include methods
of information collection and provisions at various organizational levels, improvements in information formats
and procedures being adopted by the organization, etc. The information should be at the right time, in the right
format, through the right medium, with the right contents and no redundancies.
System Design must be implementable within the given resources and must be maintainable easily. The
design process should consider that resources spent on them should be minimal, maintainability should be made
easy with less complex design, the benefit derived should be more than the cost, flexibility to adapt to changes
and the organization should be integrated.
An Information System can be any organized combination of people, hardware, software,
communications networks, and data resources that collects, transforms, and disseminates information in an
organization.
2.
An Information Systemmodel consists of the following:-
• Resources such as people, data, hardware, software and networks are used by Information Systems.
• Information Processing consists of system activities of input, processing, output, storage and control.
The major roles of Information Systems are:-
1. Support Business Processes
2. Support Decision Making
3. Support Competitive Advantage
Types of Information Systems
1. Operations support systems produce a variety of information products for internal and external use,
which process data used by business operations. These have three further categories:-
a. Transaction processing systems record and process data resulting from business transactions.
Transactions are processed in two basic ways:
i. Batch, where transactions are accumulated over a period of time. A group of entries are
made at a time; which are accepted by the information system, on a command by the
user, for updating the records.
ii. Real-time or on-line, where processing is done immediately. Whenever an activity takes
place in the organization, an entry is made in the information system in the form of a
record and the computer automatically updates it’s all other records affected by the entry
b. Process control system monitors and controls physical process
c. Enterprise collaboration systems enhance team and workgroup communication and productivity
and are also called office automation systems.
2. Management support Systems provide information and support for effective decision-making. These are
of following types
a. Management Information Systems provide information in the form of reports and displays to
managers and many business professionals
b. Decision support systems give direct support to managers during the decision-making process. It
provides some indications to a user on the basis of information stored in the system and the
parameters provided by the user.
c. Executive information systems provide critical information from a wide variety of internal and
external sources, in easy-to-use displays, to executives and managers.
3. Expert systems provide expert advice from operational chores like equipment diagnostics or decisions
for loan portfolio management.
4. Knowledge management systems support the creation, organization and dissemination of business
knowledge to employees and managers throughout the company.
5. Functional business systems focus on operational and managerial applications in support of basic
business functions such as accounting or marketing.
6. Strategic information systems apply IT to firm’s products, services, or business processes to help it gain
a strategic advantage over its competitors.
7. Cross functional Information Systems interact with several types of Information Systems that provide a
variety of functions.
The success of an Information System is measured not only by its efficiency in terms of minimizing costs,
time and the use of information resources, but also by the effectiveness of Information Technology in
supporting an organization’s business strategies, enabling its business processes, enhancing its organizational
structures and culture, and increasing the customer and business value of the enterprise.
Information systems can be classified on the following basis
3.
1. By function
a. Operations (Resources, processes, products)
b. Administrative (support functions)
c. Planning and control (management use)
d. Environmental (e.g. competition)

Management Information System (Definition)
Management comprises the process or activities that describe what managers do in the operation of their
organization: plan, organize, initiate and control operations.
Because decision making is a fundamental pre-requisite to each of the forgoing processes, the job of an MIS
becomes that of facilitating decisions necessary for planning, organizing and controlling the work and functions
of the business,
Information is different from data. Data is the plural of ‘datum’. Data are raw facts and figures or observations,
typically about physical phenomena or business transactions e.g. the sale transaction. Data may not currently be
used in a decision process and usually takes the form of historical records that are recorded and filed without
immediate intent to retrieve for decision making.
4.
Information is datathat has been converted into a meaningful and useful context for specific end users. It
consists of data that have been retrieved, processed, or otherwise used for informative or inference purposes,
argument, or as a basis for forecasting or decision making. It is placed in a context that gives its value for
specific end users. The value added process for data is where
(i) Its form is aggregated, manipulated, and organized
(ii) Its content is analyzed and evaluated
(iii) It is placed in a proper context for human user
Processing of data into information can involve anything from calculating, comparing, sorting, classifying, and
summarizing to updating existing data. The input for processing is data the output is information
System is a set of elements joined together for a common objective. A subsystem is part of a larger system with
which we are concerned.
The system concept of MIS is therefore one of optimizing the output of the organization by connecting the
operating systems through the medium of information exchange.
The objective of an MIS is to provide information for decision making on planning, initiating, organizing
and controlling the operations of subsystems of the firm and to provide a synergistic organization in the process.
MIS is the automating of routine and structured tasks to support decision making.
• MIS support decision making in both structured and un-structured problem environments
• MIS support decision making at all levels of the organization
• MIS are intended to be woven into the fabric of the organization, not standing alone
• MIS support all aspects of the decision making process.
• MIS are made of people, computers, procedures, databases, interactive query facilities, and so on. They
are intended to be evolutionary / adaptive and easy for people to use.
The need for synergy in organization calls for the systems approach in management. It has been accelerated
by two major reasons:
• The increased complexity of business
• The increased complexity of management
The increased complexity of business can be attributed to four primary causes
(i) Technological revolution
(ii) Research and development
(iii) Product changes
(iv) Information explosion
The increased complexity of management can be met by following four breakthroughs or developments:
(i) The theory of information feedback systems
(ii) A better understanding of the decision making process
(iii) Operations research or management science techniques that permit an experimental or simulation
approach to complex problems
(iv) The electronic computer
Management Information System consists of a group of people, a set of manuals, and data processing
equipment (a set of elements) select, store, process and retrieve data (operate on data and matter) to reduce the
uncertainty in decision-making (seek a common goal) by yielding information for managers at the time they can
most efficiently use it (yield information in a time reference).
5.
A business processis a related group of steps or activities in which people use information and other
resources to create value for internal or external customers. These steps are related in time and place, having a
beginning and end, and have inputs and outputs.
A process’s value added is the amount of value it creates for its internal or external customer.
There are three different types of business processes.
(i) Processes that cross functional area
(ii) Processes related to a specific functional area
(iii) Activities and sub processes occurring in every functional area.
The set of processes a firm uses to create value for its customers is often called its value chain.
The Managers of tomorrow
Changes in behavior of people and our understanding of how to motivate people in the work environment
have progressed quite slowly despite many promised gimmicks.
Changes in physical systems such as the factory production system, the physical distribution system, the
data processing system or the engineering development and test system are occurring rapidly with the
accelerating progress in technology.
Management has existed since people first realized that a co-operative society was necessary to accomplish
their goals. There are many different ways to do any particular type of work. A crucial management
responsibility is to identify ways to do work more efficiently and to produce better products and services.
Many organizations and manager make the basic mistake of believing that a management information system
can be designed or made operational without the backup of an adequate management system. Given an adequate
management system, an information system can be designed upon its foundation.
An information system provides the manager with the information needed in the form, place and time to
perform the job according to the specifications of the management system.
A new system (such as Information system) when introduced, provides newly emerging behavioral patterns.
This change has two facets: technological and social. The social change gains resistance. Three positive steps
for effecting change based on our knowledge of organizational behavior are:
1. Create a climate for change
2. Develop effective agents of change
3. Modify the required organizational system in the light of anticipated emergent behavior.
The management process and information needs
Environmental information consists of:
(1) Political and governmental considerations
(2) Demographic and social trends
(3) Economic trends
(4) Technological environment
(5) Factors of production such as source, cost, location, availability, accessibility, and productivity of the
major production factors of labor, materials and parts and capital
Competitive information considers:
(1) Industry demand
(2) Firm demand
(3) The competition:-
a. Past performance
b. Present activity (price strategy, advertising, campaigns etc)
6.
c. Future plan(new products)
Internal Information such as
(1) Sales Forecast
(2) Financial Plan
(3) Supply factors (labor, capital, plant and equipment, organization etc)
(4) Policies
“Management is the art of getting things done”. In the process of, a manager uses human skills, material
resources and scientific methods to perform all activities leading to the achievement of goals.
The advantage of viewing management as a system is that it enables us to see the critical variables, constraints
and their interaction with one another. It forces the manager to look at the situation in such a way that due
regard is given to the consequences arising out of interaction with the related elements or subjects.
Approaches to management
1. Fredrick W Taylor, recognized as the father of scientific management states his rules as follows:
a. Replace the rules of thumb with scientific rules
b. Obtain a harmony in group action
c. Achieve cooperation of human beings, rather than chaotic individualism.
d. Work for a maximum output
e. Develop all workers to the fullest possible potential for their own highest possible prosperity
2. Henry Fayol states his principles of operational management as:
a. Division of work
b. Authority and responsibility
c. Discipline
d. Unity of command
e. Unity of direction
f. Subordination of individual to corporate interest
g. Remuneration
h. Centralization
i. Scalar chain
j. Order
k. Equity
l. Stability of tenure
m. Initiative
Functions of the Manager
1. Planning is a process of determining the goals and objectives and evolving strategies, policies, programs
and procedures for the achievement of these goals. The essence of the process is decision making. The
planning process consists of three steps (i) Forecasting (ii) Determining the alternative course of action
(iii) Evaluating the best course of action.
2. Organization involves evolving the structure of the people working in the organization and their roles.
Building a meaningful effective structure of authority and the relationship is known as organizing. It
should consider the span of control, the centralization and decentralization methods, delegation of
authority, formal and informal setup.
3. Staffing involves manning the positions in the organization structure. It requires appropriate selection of
the person or persons ensuring that they together will achieve the goals and objectives of the
organization. Ensuring that the right person is at the right place, and has a good job environment. The
WBS helps in determining the job specifications. The schedules for projects play an important role in
determining number of employees.
7.
4. Directing isa complex task of implementing the process of management. In the process, the manager is
required to guide, clarify and solve the problems of the people and their activities. It is necessary to
motivate the people to work for the goals with an interest and a confidence. Different methods of
leadership are present. Autocrative leader decides what should be done. Supportive leader encourages
initiatives by employees.
5. Coordinating is the function which brings a harmony and smoothness in the various group activities and
individual effort directed towards the accomplishment of goals. It is a process of synchronizing
individual actions and the efforts which may differ because of the differences in the personal goals and
the common goals, the difference in the interpretation of methods and directions.
6. Controlling is a process of measurement of an output, comparing it with the goals, the objectives and the
target, and taking corrective actions, if the output is falling short of the stated norms. Controlling ensures
the achievement of the plan. Controlling has following three functions (i) establish standards (ii)
measure performance (iii) correct deviations if they occur.
Managers and the Environment
1. Economic environment consists of capital, labor, price changes, productivity, fiscal and monetary policy
and customers.
2. Technological environment
3. Social environment is built around the attitudes, the desires, the expectations, the degree of intelligence
and education, the beliefs and customs, the religion, the caste and creed of the people.
4. Political environment
5. Ethical environment consists of laws and business ethics which emerge from the professional conduct,
the business norms and codes on confidentiality, the payment and documentation, the adherence to
generally accepted accounting standards.
Management by Exception
When the management operates under time constraint, each manager has to allocate specific time for the several
demands made on his time. An efficient manager tries for selective attention to manage within the available
time resource. The principle evolved, therefore, is of the management by exception.
The organization system consists of:
(1) The formal organizational system as described in the charts, policies and procedures.
(2) The informal organization
(3) The individual as a system
(4) The Management Information System
(5) The organizational communication system
(6) The power system
(7) The functional system
(8) The management process system
(9) Material logistics system
Delegation of authority in an organization depends upon the following factors
(1) Cost: The more costly the decision, the more likely it is to be centralized
(2) Uniformity of policy: The more uniform and centralized a policy (the less need there is to delegate
authority)
(3) Complexity of the organization: the more complex the organization, the greater the need for
coordination and centralization of authority.
(4) Custom of the business: The authority determines authority delegation.
(5) Availability of good managers encourages delegation.
Information and Organizing
8.
The system’s viewof the organization takes into account the interaction and flow of information. The
organization should be designed according to the information flow and other factors of information chosen to
plan and control performance.
Diagram showing methods of departmentalization
Transaction Processing
When a transaction is recorded manually, a copy of the document is usually used for data preparation.
Special data preparation methods are keydisk (i.e. through a keyboard), optical character recognition (OCR)
or magnetic ink character recognition (MICR)
The data is validated to determine its correctness and completeness. Subsequently the machine-readable
stored data (master file) related to or affected by the transaction is updated and outputs are prepared in the
form of documents and reports.
Reasons for preparing transaction documents are:-
(1) Informational: To report, confirm, or explain proposed or completed action
(2) Action: To direct a transaction to take place (e.g. shipping orders etc)
(3) Investigational: for background information or reference by recipient
A single document or different copies of it may serve both action and informational purposes. E.g.
one copy of the sales order confirmation may be sent to the customer to confirm the order; a second copy may
be used as an action document to initiate filling of the order.
Transaction records are distributed to other departments to respond to queries, can be saved on
terminal for authorized reference, or scanned by managers for unusual occurrences. However reports and
analyses solve the managerial purpose better.
Transaction can be processed in batch or in real-time. One advantage of real-time processing is that
the error checking or validation is done immediately, causing early detection and tracing or error. The time
delay in case of batch processing can make tracing of error difficult.
The processing trial is needed by external auditors and certain tax regulators. It should meet
following three requirements
(1) Any transaction can be traced from the source document through processing to outputs and to totals
(2) Any output or summary data can be traced back to the transactions or computations used to arrive at the
output or summary.
9.
Information
Information as aSystem
The information system receives inputs of data and instructions, processes the data according to the
instructions, and outputs and results. The information system can be divided into five major subsystems, each of
which can be further divided.
1. Hardware and system software: The computer hardware and the system software necessary for hardware
operation.
2. Management and administration
3. Operations
4. Application system development and maintenance
5. Application systems
Information is efficient if it is correct, complete, unambiguous, validated, timely and organized. Information is
effective if it serves the purpose of decision correctly.
The value of information may be theoretically determined by the value of a change in decision-making
behavior.
Utility of information
1. Form utility: As the form closely matches decision maker, its value increases
2. Time utility: Information has greater value to the decision maker if it is available when needed.
3. Place utility: Information has greater value if it can be accessed or delivered easily.
4. Possession utility: If the dissemination of information to others is controlled.
There are two aspects to information. The first is to derive information from the data, through data processing,
and the second is to communicate it properly to the concerned people.
Methods of improving communication are massage summarizing (to reduce the amount of data to be
transmitted) and message routing (sending information only to the people concerned). The information
distribution can be controlled to improve communication. In message delay, transmission is delayed to avoid
overload, to distort, inhibit, or suppress transmission. In message modification or filtering summarizes data or
blocks certain data by filtering. In uncertainty absorption, inferences are drawn for the data, and inferences,
instead of the data are transmitted. In presentation bias, the information is presented in a way to convey the
desired message.
Value of information in decision making: The value of information is the value of the change in decision
behavior caused by the information less the cost of obtaining the information.
Value of information other than in decision: The information can be used for motivation, background building
and model building.
Information resource management is an approach to management based on the concept that information is an
organized resource. The scope if IRM includes data communication, word processing, personal computers and
traditional data processing. It emphasizes the organizational effectiveness of the information system resource
rather than the technical sophistication or efficiency of the hardware and software.
Component activities that make up the overall information resources function are:
1. Data processing
2. Telecommunications
3. Office automation
Information Resource Executive (Chief Information officer (CIO))
His responsibility includes the following
10.
1. responsibility for central data processing and data communication systems
2. Coordination of organization wide information system planning
3. Maintaining infrastructure for technical services
4. Acquisition and dissemination of knowledge and expertise regarding new technology

12.
• Strategic planning: Definition of goals, policies, and general guidelines charting course for organization.
Determination of organizational objectives. (Long term)
• Management control and tactical planning: Acquisition tactics, plant location, new products,
establishment and monitoring of budgets. (medium tenure)
• Operational planning and control: Effective and efficient use of existing facilities and resources to carry
out activities with budget constraints. (Short term)
Decisions making in management comprises of Structured and unstructured decisions. Structured decisions
have a pattern and logic. Unstructured decisions are made by intuition and human judgment is involved
Two approaches exist to defining the subsystems of an MIS.
• According to the organizational functions such as marketing, production, logistics, personnel, finance
and accounting, information processing, top management
• According to managerial activities such as transaction processing, operational control, management
control, strategic planning
13.
Quality in InformationSystems
An application has quality relative to its primary and secondary users, operations personnel, control personnel,
maintenance personnel, and so forth.
Quality in information systems has a number of characteristics. The importance of each depends on the
application and its context. The following are some of the characteristics included in the concept of quality in
information systems:
Complete Data All data items are captured and stored for use. Data items are
properly identified with time periods.
Accurate data The correct data values are recorded
Precise data Measurement of variables meets user needs for precision
Understandable output The output of the system is understandable
Timely output The output of the application is available in time for actions
and decisions
Relevant output The outputs are relevant to the actions and decisions to be
taken
Meaningful output The format, labeling, data provided, and context in which data
is presented makes the output meaningful for actions and
decisions
User friendly operation The system provides user interfaces that are understandable
and designed to confirm to human capabilities
Error resistant Suitable error prevention and detection procedures are in
operations place. There are procedures for reporting and correcting
errors. Various audit procedures are applied.
Authorized use Only authorized personnel have access to facilities,
applications and data
Protection system and The system and its operations are protected from various
operations environmental and operational risks. There are provisions for
recovery in the event of failure or destruction of part or all of
the system.
The role of top management in information system quality control is to establish the overall organization
structure, select the information system executive, approve the information system plan and budget, and
evaluate performance.
The information system executive has the responsibility for organizing and supervising the various control and
quality assurance activities in information systems.
There are certain control and quality assurance functions that need to be performed in information system
operations. The major functions are:
1. Librarian
2. Processing control
3. Access control
4. Database administration
5. Backup and recovery
6. Application development quality assurance

Decision Support Systems
Businessdecisions are those, which are made in the process of conducting business to achieve its objectives in a
given environment. Their major characteristics are:
• Sequential in nature
• Exceedingly complex due to risks and trade offs
• Influenced by personal values
• Made in institutional settings and business environment
Problems in making rational Decisions
• Ascertaining knowledge
• Insufficient knowledge
• Not enough time to be rational
• The environment may not cooperate
• Other limitations
Decision Process
• Intelligence: Searching the environment for conditions calling for decisions
• Design: Inventing, developing, and analyzing possible courses of action.
• Choice: Selecting an alternative or course of action from those available.
Important aspects of these phases
• Problem finding is conceptually defined as finding a difference between some existing situation and
some desired state. Expectations can be based on historical models, planning models, models of other
people such as superiors, extra organizational models.
• Problem formulation clarifies the problem, so that design and choice activities operate on the right
problem. Strategies of reducing complexity are determining boundaries, factoring problem into smaller
problems, focusing on controllable elements.
• Developing alternatives involves creativity which can be enhanced by aids such as scenarios, analogies,
brainstorming, checklists, templates etc.
• Decision making involves consideration of certainty, risk and uncertainty of occurrence
Nature of decisions
Programmed verses non-programmed decisions
• Non-programmed decisions have no pre-established decision rules or procedures
23.
• Programmed decisions can be pre-specified by a set of rules or decision procedures. They imply
decision making under certainty because all outcomes are known.
Users of DSS
1. Subscription mode: Regular reports received by user
2. Terminal user: Online access through system
3. Clerk mode: Direct use but like batch processing
4. Intermediary mode: Intermediaries perform analysis and interpret the report
The primary requirement of DSS for intelligence is the ability to search the database for opportunities and
problems. These searches can be summarized as:
1. Structured, continuous search (On regular basis)
2. Structured ad hoc search (Once in a while)
3. Unstructured search (through trial and error)
Report elements that assist in problem finding
1. Summarization (Totals and ordering)
2. Comparison (with plans or competitors)
3. Prediction (forecast)
4. Confirmation (for audit or validation)
Types of business decisions
Decision Operational Management Tactical Management Strategic Management
Structure
Unstructure Cash management Business Process New e-business initiatives,
d Reengineering, Workgroup Company reorganization
Process Analysis
Semi Credit management, Employee performance Product planning, Mergers
structured Production scheduling, Daily appraisal, Capital budgeting, and acquisitions, Site
work assignment Program budgeting location
Structured Inventory control Program control
• Decision making at the operation level is a situation of certainty. Decision making at the middle level is
of the risk type because of difficulty in forecasting. At the top level it a situation of total uncertainty on
account of insufficient knowledge of the external environment.
Types of Models
• Behavioral Models are useful in understanding the behavior amongst the business variables. Examples
are
– Regression models (Y=C+R.X)
24.
– Time seriesanalysis
– Market research methods
– Ratio analysis for financial assessment e.g. current ratio=current assets/current liabilities
• Management science models
– Budgeting models
– Break even analysis model (revenue=fixed cost + variable cost)
– Return on investment analysis model
– Cash budgeting
– Procedural models (Economic order quantity/minimum inventory)
• Operation research models
– Linear programming
– Inventory control models
– Material requirement planning
Methods for selection of decision alternatives
• Optimization Technique such as linear programming. These methods are used in cases where decision
making situation is closed, deterministic and requires to optimize the use of resources under conditions
of constraints.
• Payoff Analysis is used when the alternatives and outcomes are not known. A matrix is prepared to
evaluate the decisions. (probabilities are set for occurrence)
• Utility and indifference curve considers non monetary benefits of decision also and evaluates using the
matrix of Payoff Analysis.
• Decision Tree Analysis is used when a sequence of decisions are to be made.
• Uncertainty avoidance. Example: Choosing to earn $10 with 90% probability than choosing to earn
$100 with 12% probability
• Organizational learning helps in influencing decision making
• Game Theory
• Statistical inference such as regression and correlation, testing of hypothesis.
Decision Support Systems
Decision Support Systems are computer-based information systems that provide interactive information
support to managers and business professionals during decision making process. Decision support systems use
analytical models, specialized databases, a decision maker’s own insights and judgments and an interactive,
computer based modeling process to support the making of semi structured and unstructured business decisions.

Typical MIS Reporting
• Periodic Scheduled Reports
– Example: Monthly Financial Statements
• Exception Reports
– Example: List of items out of stock
• These reports contain information but they might not directly help you determine the best decision to
make.
• Demand Reports and Responses
– Available whenever a manager needs them, updated in real-time.
• Push Reporting
– Information is pushed to a managers computer
– Example: Report is pushed every time a supplier is late with a shipment
• MIS Reporting is all about giving managers feedback and doesn’t necessarily help directly with decision
making.

Artificial Intelligence Technologies in Business
Artificial Intelligence is a field of science and technology based on disciplines such as computer science,
biology, psychology, linguistics, mathematics, and engineering.
The goal of IT is to develop computers that can think, as well as see, hear, walk, talk and feel.
Attributes of Intelligent Behavior
27.
• Think and reason
• Use reason to solve problems
• Learn or understand from experience
• Acquire and apply knowledge
• Exhibit creativity and imagination
• Deal with complex or perplexing situations
• Respond quickly and successfully to new situations
• Recognize the relative importance of elements in a situation
• Handle ambiguous, incomplete, or erroneous information
Expert systems are built using an expert system shell (knowledge base for expert system without kernel,
consisting of facts and heuristics) coupled with inference and user interface capabilities. But it has a limitation
in terms of learning of system, development cost and maintenance.
End User Computing
End-User Development (EUD)
Specifically, the practice of users developing their own information systems, is often but not always with the
support of professional systems developers. The practical involvement of end-users in application development
necessitates the easy access to computing facilities. This may be
• Timesharing on a centralized mainframe
• The use of stand alone personal computers
• The use of personal computers which are connected to local area networks and mainframes.
In addition to being provided with hardware and software, extra facilities are a necessary condition of
successful End user applications development. In particular:
• Education and training on the use of software tools
• Assistance in the technical aspects of writing, testing, and debugging applications
• Availability of reference material
• Aid in accessing the corporate database
Applications Suitable for End-user Development
Applications suitable for end-user development can be grouped into the following 5 categories:
• One time enquiries
• Simple Reports
28.
• Minor Changesto Reports or Enquiries
• Presentation of Data in Alternate Forms
• 'What if' Analyses
Applications not suitable for end-user development:
• data entry involving organization files and databases (where the data must be validated for accuracy and
reliability)
• high volumes of transactions, requiring processing efficiency and multiple processing steps
• use of 'traditional' computer languages designed for use by professional programmers, requiring detailed
statement of processing procedures and controls
• changing of data values in existing databases and files
• applications spanning several departments or divisions in the organization
• applications requiring formal documentation
• applications requiring a long development process
• applications requiring detailed formal specifications.
Who Are The End Users?
In general an end-user is anyone who has to interface to a computer who is not employed specifically to do so
(ie is not a data entry clerk or an operator). This includes executives interfacing to EIS facilities, middle
managers or technicians who use a PC or a terminal to an on-line system, clerks accessing a central database to
download data for local processing, individuals using a PC in stand alone mode for their own work, individuals
using a PC in stand alone mode for an activity which the corporate management has decided shall be done by
computer (eg office automation), clerks interfacing to a computer system which has replaced their manual
system (without their having any input) and clerks writing data preparation documents.
Web integration is, however, creating a new class of end-user. (S)he is an end-user in one organization who,
through integration (3-tier client / server), has suddenly become a user of a system in another organization. A
further complication is that now a system may have to cope with two different kinds of end-user at the same
time. For example the parcel tracking system at FEDEX could be accessed by both a company employee and an
external customer, both trying to track a parcel (though not necessarily the same parcel). We may group them
into the following categories:
• Non programming
• Command level
• End-user programmers (including senior management professionals)
• Functional support personnel
• End user computing support personnel
• DP Programmers
This list covers a very wide range of personnel carrying out a wide range of tasks throughout
organization - and the list continues to grow.
Advantages of User-developed systems
• Relieves shortage of system development personnel
• Eliminates the problem of information requirements determination by information systems personnel
• Transfers the information system implementation process to users
• Enhanced productivity of professional and white-collar workers.
• Provision of user-friendly and responsive systems.
Problems
It became clear very quickly that the managers had bought something that they didn't understand and either had
to discard the machine (as happened in many schools who were encouraged
by government to acquire computers) or had to be supported to get the most out of their purchases.
29.
The particular problemswhich were posed for the organizations into which these PCs had been
introduced were:
(a) Lack of standardization between the various purchases leading to:
(i) inability to share data;
(ii) no economy of scale in purchasing;
(iii) a variety of requirements for maintenance, in the few cases where the problem had
actually been considered.
(b) Lack of control over the requirements of legislation, such as software copyright, data
protection, health and safety and the specific legal constraints covering the organization.
(c) Demands for assistance with:
(i) systems analysis and design;
(ii) programming;
(iii) software procurement;
(iv) sizing - machines which have been purchased but are too small for the job;
(v) maintenance;
(vi) fall-back;
(vii) lack of documentation;
(viii) data security;
(ix) environmental control;
(x) file conversion and data acquisition;
(xi) data organization.

Planning
Concept of Planning in Organization
• A plan is a predetermined course of action to be taken in future. It identifies the goal to be achieved and
the steps to be taken to achieve the desired results.

Information System Plan
Process of Information System Plan Development
• Planning is the process of deciding what will be done, who will do it, when they will do it, how it will be
done, and what are the desired results.
Challenges in IS planning

Planning for Information System
• The complexity of the information resources environment suggests that planning is vital to success.
• The plan describes the structure and content of the information system and how it is to be developed.
• The organization’s strategic plan should be the basis for the MIS strategic plan.
• The overall responsibility of IS planning is the responsibility of Chief Information Officer (CIO)
Approaches to organizing and supervising the information system planning effort
• Planning staff within information systems functions (planning specialists)
• Ad hoc planning groups within information systems
• Planning group with representatives from various functions
Review of plan
• Master plan is reviewed by the steering committee which comprises of executives from major functional
areas and is executives.
• The committee also periodically reviews progress against the plan.
• The master plan is integrated in the organizational plan by top management after review and approval.
• Information system policies and procedures are defined.
Content of Master development plan/ Information System plan/ Information Resource plan
• The master plan has two components:- a long-range plan and a short-range plan. The long-range plan
provides general guidelines for direction and the short-range plan provides a basis for specific
accountability as to operational and financial performance. It consists of the following subheadings:-
– Information system goals, objectives, and architecture
– Inventory of current capabilities
– Forecast of developments against the plan
– The specific plan
Information system goals, Objectives, and architecture
– Organizational goals, objectives, and strategies
– External environment (industry, government regulations, customers, and suppliers)
– Internal organizational constraints such as management philosophy
– Assumptions about business risks and potential consequences
– Overall goals, objectives, and strategy for the information system
– Architecture of the information system
– Current capabilities
– Inventory of
– Hardware
– Software (System software, DBMS, etc)
– Application systems (classified on the basis of functional systems, organizational
strategy, maintenance need)
– Analysis of
– Expense
– Hardware utilization
– Software utilization
– Personnel utilization (further classification such as job, skill, functional area)
– Status of projects in progress
– Assessment of strengths and weaknesses
• Forecast of developments Affecting plan
– Hardware and software technological availabilities should be forecasted with expected impact on
existing IS
– Methodology changes should be forecasted
– Environmental developments such as government regulations, tax laws and competitors affecting
IS should be stated
35.
• Specificplan
– Hardware acquisition schedule
– Purchased software schedule
• System Software
• Applications software
– Application development schedule
– Software maintenance and conversion schedule
– Personnel resources required and schedule of hiring and training
– Financial resources required by object of expenditure
The master plan is prepared from the CIO’s point of view and focuses on the planning strategy e.g. if the
planning strategy for consideration is the end-user computing, then the plan will highlight the end users in the
IS.
Maintenance of master plan
• IS plan requires updating
– Changing organizational setup
– Changes in technology
– Changing needs of system
– Internal events
– Progress of new systems
– External events
Information system growth models
Assumptions of NOLAN model
• Organizational learning
• Stages cannot be skipped
• Other than the natural process, these processes can be planned, coordinated, and managed to move
through the stages effectively and efficiently
• The NOLAN stage model
The organization must go through each stage of growth before it can progress to the next one, thus giving an
insight to planning regarding the stage of an IS
Stages of Information system growth
Stages of growth Description
Initiation Early use
Expansion Experimentation, rising cost
Formalization Organizational controls
Maturity Integration of applications
Stages
NOLAN six stage model
Stage Level of control or slack
36.
I Low control. Some slack. No planning
II Greater slack due to encouraged use, integration and lack of planning
III High controls, planning given importance
IV Use of databases for integration
V Slack due to focus on strategically important systems
VI Application portfolio complete and matches organizational objectives
NOLAN alternative model
Due to technological changes the growth curve shifts as follows
Advantages and disadvantages of NOLAN model
• Advantages
– Evolutionist model as it focuses on development
• Disadvantages
– Lack of specificity as it does not define the mechanism for change
37.
Three stage modelof the planning process
• It clarifies the generic planning activities, the order of activities, and the alternative techniques and
methodologies that apply
Strategic planning stage
• McFarlan-McKenney Strategic Grid
Position in grid Organization and management of IS planning
38.
Strategic Significant general management guidance. Integration of corporate
planning and IS planning
Turnaround Same as strategic
Factory Less involvement from top management. Guidance from corporate
plan to maintain IS alignment
Detailed operational and capacity planning by IS function
Support Little top management involvement
Little or no guidance from corporate plan
Strategic fit
• Each organization has a culture which reinforces values, norms, and beliefs about the organization.
Goals, objectives, and strategy for information systems should fit with the culture in order to avoid high
resistance and high risk of failure.
Strategy Set Transformation
• Explicate the organization’s strategy set
– Delineate the organization structure for users
– Identify goals of claimants
– Identify organizational goals and strategies for each claimant group
• Validate the organizational goals from management
• Transform organizational strategy set into the information system strategy set
– Identify IS objectives for each organizational strategy
– Identify IS constraints from organizational strategy
– Identify IS design strategy based on organizational attributes
Analysis of Organizational information requirements
• Information requirements are required at the organizational level for information system planning,
identifying applications, and planning an information architecture.
• More detailed information requirements are required for detailed design of applications.
Strategy approach to the determination of Information requirements
• Constraints
– Humans as information processors
– Variety and complexity
– Complex patterns of interaction
– Unwillingness of some users
• Levels of requirements
– Organizational level
– Database level
– Detailed requirements for an application
Steps:
• Identify those characteristics of the four elements in the development process that affect uncertainty in
the determination of information requirements
– Utilizing system
– Information system or application
– Users
– Analysis
39.
• Evaluate the effect of the characteristics of the four elements in the development process on three
process uncertainties:
– Existence and availability of a set of usable requirements
– Ability of users to specify requirements
– Ability of analysis to elicit and evaluate requirements
• Evaluate the combined effect of the process uncertainties on overall requirements uncertainty
• Select a primary strategy for requirements determination based on the overall requirements uncertainty.
– Asking
• Closed questions
• Open questions
• Brainstorming
• Guided brainstorming
• Group consensus
– Deriving from an existing information system
• Existing system being replaced by the new system
• Existing system in another , similar organization
• Proprietary system or package
• Descriptions in textbooks, handbooks, industry studies etc.
– Synthesizing from characteristics of the utilizing system
• Normative analysis
• Strategy set transformation
• Critical factors analysis approach (critical success factors CSFs)
• Process analysis (Business systems planning BSP)
• Ends-means analysis
• Decision analysis
• Socio-technical analysis
• Input-process-output analysis
– Discovering from experimentation with an evolving information system
• Select one or more methods from the set of methods to implement the primary strategy
Organizing for development of MIS
Major issues are:
• Centralization and Decentralization
• Allocation of hardware and software
• Maintenance of the service level
• Fitting the organization of the MIS in corporate organization, its culture and management philosophy
Organization and management of the Information resource function
• The management of IS in many organizations is experiencing a transition from computers and data-
based information processing to information as a strategic resource and to an expanded role for
Information technology termed as information resource management.
• Reasons for such shifts are the stage of development, and technology. In the six-stage NOLAN model,
the maturity stage replicates organizational processes and there is a joint information-systems-user
accountability for information resources. There is also a match between organizational and IS structure.
The technology is highly integrated with organizational processes and thus should be managed by single
authority.
Information Resource functions
• Data processing
• Telecommunications
• Office Automation
40.
Information resource executive
Hisresponsibilities include:
• Operational responsibility for central data processing
• Coordination of information wide information system planning
• Maintaining infrastructure for technical services
• Acquisition and dissemination of knowledge
• Establishment and enforcement of standards and guidelines for all major IS applications
• Aiding of adequate placement of information systems expertise and responsibilities
Organization of the information resource function
There are three alternatives, centralization, decentralization or combined forms such as function and matrix.
Pressures for decentralized control
• Availability of low cost technology
• Backlog of development work
• User-control over operations
• Organizational Behaviour
– Psychological value of unused information
– Persuasion
– Symbol of commitment to rational choice
Pressures for centralized control
• Staff professionalism
• Corporate Database control
• Technical competence and control
• Comparative cost advantage
Centralization and decentralization of System operations
(Factors affecting location)
• Economies of scale for computer equipment
• Integration of processing
• Data communications cost
• Technological expertise to support computer operations
• Hardware installation risks
Centralization Vs Decentralization of system Development (Role of user liaison) : The development work
can be performed at one location or can be distributed along various locations of the organization. But getting
the user and developer together helps achieve effectiveness.
Centralization Vs decentralization of Allocation of Scarce Information Resources
Advantages of centralization are that it facilitates integration and overall balance of development of IS
applications. It also facilitates close adherence to an overall MIS master plan.
Decentralization is implemented using a chargeback system. A chargeback system provides a cost recovery. A
good chargeback method should have the following characteristics:
• Understand ability
• Control ability
• Accountability
• Cost/Benefit incidence
Thus it should be based on a standard rate per unit processed, such as transactions, inquiries, or reports. Fixed
prices are appropriate for development.
Information cost
Information cost scan be handled as per the following:
41.
• Overhead
• Allocation of expense
• Standard resource rates
• Standard rate per unit processed
• Fixed price
• Charges are based on CPU utilization and disk storage costs.
Management of IS personnel
• Information Analyst helps gather relevant information
• System Designer designs and models the system
• Application programmer develops the application
• Maintenance programmer helps keep the application in good form
• Program librarian takes care of all the documentation associated with the application
• Systems programmer help in system level programming
• Data communications specialist helps in communication data correctly
• Data administrator takes care of the data kept in the DBMS
• User liaison interacts with the user
• Office automation coordinator ensures tools work correctly
• Information centre analyst handles all the information
• Operator uses the application
• Data control clerk validates the data
• Data entry clerk enters the data
• Security coordinator ensure security features
Concept and process of control
Managerial control implies the measurement of accomplishment against the standard and the correction of
deviations to assure attainment of objectives according to plans.
It is a continuous process of verifying whether actions are being taken as planned and taking corrective action to
ensure that events conform to plans as closely as possible.
Nature of control
1. Control process is universal
2. Control is a continuous process
3. Control is forward looking
4. Control involves measurement
5. Control is an influence process
6. Management control is a system
7. Control is best aimed at results
8. Control is goal oriented
Elements of control
1. Planning
2. Information feedback
3. Delegation of authority
4. Remedial action
Interrelationship between planning and control
Planning is meaningless without control and control is aimless without planning. Control helps understand
the need for revision of plans if required.
42.
Benefits of control
1. Guide to operations
2. Policy verification
3. Managerial accountability
4. Employee morale
5. Psychological pressure

Enterprise Resource planning
Inorder to manage information, in order to deliver high quality information to the decision-makers at the right
time, in order to deliver high quality information to the decision-makers at the right time, in order to automate
the process of data collection, collation and refinement, organizations have to make IT an ally, harness its full
potential and use it in the best possible way.
For any organization to succeed, all business units or departments should work towards this common goal. At
the organizational level, IT should assist in specifying objectives and strategies of the organization. At the
departmental level, IT must ensure a smooth flow of information across departments, and should guide
organizations to adopt the most viable business practices.
As the departments are large, they remain closed except at the top level, unless a common system is
implemented.
An Enterprise is a group of people with a common goal, which has certain resources at its disposal to achieve
that goal. Resources included are money, material, man-power and all other things that are required to run the
enterprise. Planning is done to ensure that nothing goes wrong. Thus Enterprise Resource planning is a method
of effective planning of all the resources in an organization.
ERP is primarily an enterprise-wide system, which encompasses corporate mission, objectives, attitudes,
beliefs, values, operating style, and people who make the organization.
ERP covers the techniques and concepts employed for the integrated management of businesses as a whole,
from the viewpoint of the effective use of management resources, to improve the efficiency of an enterprise. It
is a mirror image of the major business processes of an organization, such as customer order fulfillment and
manufacturing. Its set of generic processes, produce the dramatic improvements they are capable of only, when
used to connect parts of an organization and integrate its various processes seamlessly.
Reasons for the growth of the ERP market
1. To enable improved business performance through reduces cycle time, increased business agility,
inventory reduction, order fulfillment improvement
2. To support business growth requirements through new product lines, new customers, meeting global
requirements
3. To provide flexibility, integrated, real-time decision support through improved responsiveness across
the organization
4. To eliminate limitation in legacy systems of century dating , fragmentation of data, inflexibility to
change etc
5. To take advantage of the untapped mid-market by increasing functionality at a reasonable cost, vertical
market solutions etc.
The advantages of ERP
1. Business Integration through automatic data updations
2. Flexibility to adapt to global differences
3. Better analysis and Planning capabilities by utilizing many types of support systems
4. Use of latest technology to sustain growth.
Why do many ERP implementations fail?
1. Wrong product
2. Incompetent and hazardous implementation.
3. Lack of training for employees
Integrated Management Information

ERP Market consists of the big 5 vendors (Sap, Oracle, Peoplesoft, Baan, JD Edwards) and others. The big 5
account for 61% of the market share.
SAP (Systems, Applications and products in Data Processing)
SAP ERP packages come in two versions: the mainframe version (SAP R/2) and the client/server version (SAP
R/3)
SAP products feature a sophistication and robustness unmatched by other business software solutions. SAP has
developed an extensive library of more than 80 predefined business processes, spanning each functional
software requirement.
R/3 Overview
The 3-tier architecture separates a system into three functional layers, each structured to support the demands of
its functions.
1. The database layer resides on central servers or mainframe host computers
2. The application layer holds the processing logic of the system, preparing and formatting data for
individual offices or departments.
3. The presentation layer typically on personal computers, handles all the tasks related to the presentation
of data, including user interfaces that enable easy access to complex applications and data.
SAP also incorporated And integrated the intranet and internet technologies into business solutions for its
customers.
Although designed as an integrated system, R/3’s modules can also be used individually
SAP has recently come out with BAPIs (Business application programming interface) which helps SAP interact
with third party applications

What is CRM?
CRM stands for Customer Relationship Management. It is a process or methodology used to learn more about customers'
needs and behaviors in order to develop stronger relationships with them. There are many technological components to CRM,
but thinking about CRM in primarily technological terms is a mistake. The more useful way to think about CRM is as a process
that will help bring together lots of pieces of information about customers, sales, marketing effectiveness, responsiveness
and market trends.
CRM helps businesses use technology and human resources to gain insight into the behavior of customers and the value of
those customers.
CRM Software
Sales Force Automation
• Contact management
Contact management software stores, tracks and manages contacts, leads of an enterprise.
• Lead management
Enterprise Lead management software enables an organization to manage, track and forecast sales leads. Also helps
understand and improve conversion rates.
eCRM or Web based CRM
• Self Service CRM
Self service CRM (eCRM) software Enables web based customer interaction, automation of email, call logs, web site
analytics, campaign management.
• Survey Management Software
Survey Software automates an enterprise's Electronic Surveys, Polls, Questionnaires and enables understand customer
preferences.
Customer Service
• Call Center Software
• Help Desk Software
Partner Relationship Management
50.
• Contract Management Software
Contract Management Software enables an enterprise to create, track and manage partnerships, contracts, agreements.
Example: Upside Software, Accruent Software, diCarta, I-Many.
• Distribution management Software
Using CRM, a business can:
• Provide better customer service
• Increase customer revenues
• Discover new customers
• Cross sell/Up Sell products more effectively
• Help sales staff close deals faster
• Make call centers more efficient
• Simplify marketing and sales processes
The types of data CRM projects collect
• Responses to campaigns
• Shipping and fulfillment dates
• Sales and purchase data
• Account information
• Web registration data
• Service and support records
• Demographic data
• Web sales data
The secret to an effective CRM package is not just in what data is collected but in the organizing and
interpretation of that data. That's where computers come in handy (apart from the Solitaire you can play on
them :-)) Computers can't, of course, transform the relationship you have with your customer. That does take a
cross-department, top to bottom, corporate desire to build better relationships. But computers and a good
computer based CRM solution can increase sales by as much as 40-50% - as some studies have shown.
One of the important activities of CRM is segmenting customers. To achieve this, important subsets of data,
stored in central database by ERP, are copied into a separate repository, called data warehouse. Once the data
warehouse is in place, companies can use data mining technique to help them if through transaction data in the
data warehouse. Companies look for patterns in information to identify the customer relationship.
CRM also allows:
• One-to-one marketing: Once a customer is categorized, products, promotions, and pricing can be
tailored accordingly.
• Sales force automation: Customer contacts are logged in the company's database. The customer can be
understood using past transactions and the sales representative can know the customer before visiting.
• Sales Campaign Management Software: This software lets a company organize a marketing campaign
and compile its results.
• Marketing Encyclopedia: This software serves as a database of all promotional information required by
sales representatives or customers.
• Call centre automation: The representative can get assistance about products.
• CRM needs ERP as a base since an ERP contains all the common transactions of business, relevant for
CRM
51.
Types of CRMsystems
1. Operational oriented CRM systems: It provides transactional level data on individual products,
transactions and customers
2. Analytical CRM systems: It holds aggregate data and supports for strategic planning process
3. Collaborative CRM systems: It is the use of web technologies to facilitate customer, staff and business
partner’s communications.
Stages of CRM
1. Customer selection
2. Customer acquisition
3. Customer retention
4. Customer extension
Procurement Management
Procurement management system provides a solution to conduct centralized purchase based on the demands
individually submitted and approved by competent authorities. It provides a way to businesses that how they
purchase their inventories at a reasonable price.
Procurement is often regarded as the narrow process of inviting bids and awarding contracts. The cycle
approach to procurement ensures that the early steps in the process and the later steps are given the same
emphasis
Procurement Process
52.
The following maybe involved in the procurement cycle as it depends upon individual implementation
1. Those staff assuming project management roles: project owner, project manager, project board, project team
roles.
2. The contract or relationship manager
3. Trained procurement staff
4. Stakeholders such as users, existing suppliers, finance section.
5. Other professional advisors such as accountants, legal advisors, technical advisors
Critical Success Factors
1. Do not apply the procurement process in a mechanistic manner. Good judgement, applied ethically and with a
transparent audit train
2. Project management, contract management and a robust procurement process together offer a great chance of
success
3. Procurement should be recognised as a profession and carried out by skilled staff
4. The gateway process is an essential project management tool particularly for high medium risk procurements.
Procurement Risk Matrix
Ethical Procurement Behavior
1. Disclosure of Interest should be disclosed for any transaction
2. Gifts and hospitality whether accepted or rejected, should be recorded, and under no circumstances
should the supplier be able to influence.
3. Confidentiality of Information should be maintained
4. Fair Competition
5. Professionalism
6. Responsibilities of setting an ideal behaviour, presenting an open image, ensuring that instructions are
understood, supervising staff, regularly rotating posts, etc.
Supply Chain Management
Supply Chain Management encompasses every effort involved in producing and delivering a final product or
service, from the supplier’s supplier to the customer’s customer. Supply Chain Management includes managing
53.
supply and demand,sourcing raw materials and parts, manufacturing and assembly, warehousing and inventory
tracking, order entry and order management, distribution across all channels, and delivery to the customer.
Supply chain objective
• Maximize overall value generated
• Value strongly correlated to supply chain profitability – the difference between the revenue generated
from the customer and the overall cost across the supply chain
• Example: A customer purchasing a computer from Dell pays $ 700 (the revenue)
• Dell and other stages of the supply chain incur cost to convey information, produce the components,
store them, transport them, transfer funds, etc.
Why is SCM Important?
• Strategic Advantage – It Can Drive Strategy
* Manufacturing is becoming more efficient
* SCM offers opportunity for differentiation (Dell) or cost reduction (Wal-Mart or Big Bazaar)
• Globalization – It Covers The World
* Requires greater coordination of production and distribution
* Increased risk of supply chain interruption
* Increases need for robust and flexible supply chains
• At the company level, supply chain management impacts
* COST – For many products, 20% to 40% of total product costs are controllable
logistics costs.
* SERVICE – For many products, performance factors such as inventory availability
and speed of delivery are critical to customer satisfaction.

Modeling for SCM
• Forecasting Models
- These models allow prediction of demand based on past data or other parameters that are
independently available. They enable better planning, given the lead-time necessary for response.
• Location Models
- These models identify the optimal location of facilities such as plants and warehouses, considering the
inbound and outbound transportation costs as well as the fixed and variable costs of operation at the
locations under consideration. These are usually formulated as Mixed Integer Programming Models
• Distribution Network Design Models
- These models are usually comprehensive in nature, deciding between two, three and even four stages
of distribution network, location of warehouses and break-bulk points, and sometimes even the
transportation.
• Allocation Models
- These models help in optimally allocating commodities from sources to destinations in a multi-source,
multi-destination environment. The costs considered for optimisation are production costs and warehousing
costs. The constraints considered can be due to demand, capacity, route restrictions, etc.
• Inventory Models
- Inventory plays a major role in SCM.
- Inventory can be of various types such as:
- Batching and shipment inventories
- Buffer stocks to take care of uncertainties
- Pipeline inventory ( primary and secondary transportation )
These models minimize the total relevant cost, based on trade-offs among, inter alia, inventory carrying
cost, ordering cost, stock-out cost, transportation cost, taxes & duties, etc.
• Routing Models
- These models allow optimal routing on a transportation network from a given source to a destination.
The models used are the Shortest Path Problem, the Traveling Salesman Problem and the Vehicle Routing
Problem. Decision Support Systems that interactively use the expertise of the decision maker by providing
graphical support through a map (i.e., using a Geographical Information System) are also very useful in such
decisions.
• Scheduling Models
58.
- These modelsenable allocation of resources to particular activities. Depending on the criteria of
interest and the number of resources, the models are of aid in evaluating appropriate rules for allocation.
• Alternative Analysis
- This model simply proposes the identification of alternatives, criteria for decision making and analysis
of the alternatives across the criteria to arrive at the best choice. Formal approaches such as simulation and
analytic hierarchy process could be used in assessing the implications of the criteria.
