9. What is DSS?
Decision Support System
is a computer-based information system that
supports business or organizational decision-
making activities.
is an interactive software-based system intended
to help decision makers compile useful
information from a combination of raw data,
documents, and personal knowledge, or business
models to identify and solve problems and make
decisions.
10. What is DSS?
provides tool to manager to assist them in
solving semi- structured and unstructured
problems in their own.
is an information system that support to
managers for decision making.
11. A brief History?
Academic Researchers from many disciplines has
been studying DSS for approximately 40 years.
According to Keen and Scott Morton (1978), the
concept of decision support has evolved from two
main areas of research: the theoretical studies of
organizational decision making done at the
Carnegie Institute of Technology during the late
1950s and early1960s, and the technical work on
interactive computer systems, mainly carried out at
the Massachusetts Institute of Technology in the
1960s.
12. A brief History..
It is considered that the concept of DSS
became an area of research of its own in the
middle of the 1970s, before gaining in
intensity during the 1980s.
In the middle and late 1980s, Executive
Information Systems (EIS), group decision
support systems (GDSS), and organizational
decision support systems (ODSS) evolved
from the single user and model-oriented DSS.

25. ALTERNATIVES OF DSS
NEEDS OF DSS: DSS have become necessary
for today’s manager because of the following
reason:
1. FAST COMPUTATION
A decision maker can perform a large number
of computation very quickly and that too at a
low cost with the help of computer support
system.
26. ALTERNATIVES OF DSS
2. ENHANCED PRODUCTIVITY
Decision support system can enhance the
productivity of support staff and also enable
the group members to disclose the problems
among themselves as distance.
3. BETTER DECISION
Computer support system can help a decision
maker in arriving at a better decision.
27. ALTERNATIVES OF DSS
4. DATA TRANSMISSION
Sometimes the data, which may be
stored at different locations, may be
required to be transmitted quickly from
distant locations. Computer support
system can be search, stored and
transmitted the required data quickly and
economically.
28. ROLE OF DSS IN BUSINESS
DSS is computer based information for management
decision maker who deal with the semi- structure
problems. DSS play an important role in business, it
performs various activities. The role of DSS is explained
as follows:
1. WHAT IF ANALYSIS
this is the process of accessing the impart of variables.
This helps manager to be proactive rather that reactive
in their decision making. This analysis is critical for
semi- structured and unstructured problem because the
data necessary to make such decision are not available.
29. ROLE OF DSS IN BUSINESS
2. GOAL ORIENTED
it is a process of determining the input
values required to achieve a certain goal.
3. RISK ANALYSIS
risk is the important factor which affects
the business enterprise. DSS allows
manages to the risk associate with various
alternatives.
30. ROLE OF DSS IN BUSINESS
4. MODEL BUILDING
DSS allows decision maker to identify the
most appropriate model for solving the
problems.
5. GRAPHICALANLYSIS
this help managers to quick digest large
volumes of data and visualize the impacts of
various because courses of action.
31. ROLE OF DSS IN BUSINESS
They recommends the use of graph when:
a. Seeking quick summary of data
b. Forecasting activities
c. Detecting trends over time
d. Composing points and patterns at different
variables
32. STEPS IN CONSTRUCTNG DSS
1. IDENTIFICATION OF THE PROBLEM
in this stage the developer and the knowledge engineer
interact to identify problems. The following points are
discussed:
a. The scope and intent are analyzed.
b. The return of investment analysis is done.
c. The amount of resources needed is identified.
d. Areas in the problems that can give much trouble are
identified and conceptual solution of the problem is
found.
e. Overall specification is made.
33. STEPS IN CONSTRUCTNG DSS
2. DEVELOPMENT OF PROTOTYPE
before the development of a prototype we decide
the knowledge level to solve the particular
problem. For this we adopted some methods in
sequence . After this the taste of knowledge of
Engineer and developer which interact frequently
and domain specific knowledge is entrance. When
knowledge representation scheme and knowledge
is available a prototype is constructed.
34. STEPS IN CONSTRUCTNG DSS
3. DECISION ABOUT MODE OF
DEVELOPMENT
once the problem is identified, the immediate
step would be to decide about the vehicle for
development. He can develop shell for
development by any programming language. In
this stage, various shell and tools are identified
and analyzed for their suitability. These tools
whose features fit the characteristic of the
problem are analyzed in details.
35. STEPS IN CONSTRUCTNG DSS
4. PROTOTYPE VALIDATION
the prototype under goes the process of testing
for various problems and revision of the prototype
takes place. It is very important step of DSS.
5. PLANNING FOR FULL SCALE SYSTEM
in prototype construction, the area in the problem
that can be implemented with negative case is
first choice intensive planning is done.
36. STEPS IN CONSTRUCTNG DSS
6.FINAL IMPLEMENTATION,
MAINTENANCE AND EVALUATION
This is the final stage of DSS Life Cycle.
The full scale system developed is
implemented at the basic resources
requirement are fulfilled and parallel
conversion.
37. GROUP DECISION SUPPORT
SYSTEM (GDSS)
is a decision support system that
facilitates decision making by a team of
decision makers working as a group.
is an interactive computer based system
that facilitates solution of unstructured
problem by a set of decision makers by
working together as a group.

making by a team of decision maker working
as a group.
a GDSS is an interactive computer based
system that facilitates solution of unstructured
problem by a set of decision makers working
together as a group.
39. CHARACTERISTICS OF GDSS
The goal of GDSSs is to improve the productivity of
decision-making meetings, either by speeding up the
decision-making process or by improving the quality of
the resulting decisions, or both. This is accomplished by
providing support for the exchange of ideas, opinions,
and preferences within the group.
1. Supporting parallel processing of information and
idea generation by participants.
2. Enabling larger groups with more complete
information, knowledge, and skills to participate in the
same meeting.
40. CHARACTERISTICS OF GDSS
3.Permitting the group to use structured or
unstructured techniques and methods of arriving at
decisions.
4. Offering rapid and easy access to external
information.
5. Allowing nonsequential computer discussion.
(Unlike oral discussions, computer discussions do
not have to be serial or sequential.)

13. The GDSS is designed to encourage
activities such as idea generation, conflict
resolution and freedom of expression.
44. TYPES OF GDSS
1. DECISION NETWORK
this type helps the participants to communicate
each other through network or through a central
database. Application software may used
commonly shared models to provide support. The
common implementation using local area network
and microcomputer. The technology filters out
many group dynamics of participative meeting.
45. TYPES OF GDSS
2. DECISION ROOM
Participants are located at one place i.e. the
decision room. The purpose of this is to
enhance participants interaction and decision
making by computerized within a fixed period
of time using a facilitators.
46. TYPES OF GDSS
3. TELE CONFERENCING
groups are composed of numbers or groups
that are geographically disordered
teleconferencing provides interactive
connection within two or more decision rooms.
This interaction will involved transmission of
computerized audio visual information.

because under GDSS, the decision are taken by
group.
2. TO SOLVE THE PROBLEM
GDSS provides solution to unstructured
problems. GDSS collects various types of
information at various sources.
49. ADVANTAGES OF GDSS
3. TO MINIMIZE THE RISK
GDSS allows managers to assess the risks
associated with various alternatives. This helps
managers to be proactive rather than reactive.
4. TO COLLECT THE AMOUNT OF
INFORMATION
GDSS collect information at various sources for
decision making. This information minimizes the
risk.
50. ADVANTAGES OF GDSS
5. TO PROVIDE INTERACTIVE COMMUNICATION
GDSS provide interactive information. It takes better
decision through the interactive communication.
6. TO IMPROVE THE DECISION MAKING
PROCESS
GDSS improve the decision making process because
GDSS is a goal-oriented when the GDSS is designed,
the goal is considered.
51. ADVANTAGES SOF GDSS
7. TO MAKE COORDINATION IN VARIOUS
ACTIVITIES
GDSS decision are taken by a group
GDSS. The work is divided into different
parts then each DSS performs own work.

59. Group Decision Support System
6. Setting Priorities and Making Decisions
Group Decision Support System help to
set the priorities and give importance to
those problems which are more critical.
60. GROUP DECISION SUPPORT
SYSEM
DECISION MAKING
is an essential part of modern management. A
manager’s life is filled with a constant series of
decision- where to invest profits, what to do
about an employee who is always late, where
should the firm’s new warehouse to built, what
subject will have to priority at the department
meeting the next morning and so on..
61. Group Decision Support System
decision which are relatively minor are taken
almost subconsciously, the rules and patterns
of behavior established over many previous
encounters with the problem.
is a key part of a manager’s activities. It
permits through all managerial functions such
as planning, organizing, directing and
controlling.
62. Group Decision Support System
in planning it is through the process of
decision making that objectives and policies
are down and the managers decides many
things such as what to produce, what to sell,
where, when, now and so on..
in organizing, decision making relates to the
choice of structure, nature and form of
organization, division of work, delegation of
authority, fixing of responsibility and the like.
63. Decision Making
in directing, decision making relates to
determining the course, deciding the orders
and instructions to be given, providing
dynamic leadership and similar other issues.
In controlling, the decision relate to the laying
down of performance standards strategic
control points, procedure for control, and so
on.
64. Decision Making
Decision
is a choice between two or more alternatives.
This implies three things:
1. When managers make decision they are
choosing- they are deciding what to do on the
basis of some conscious and deliberate logic or
judgement.
65. Decision Making
2. Managers have alternatives available
when they are making a decision. It does
not require a wise manager to reach a
decision when there are no other possible
choices. It does require wisdom and
experience to evaluate several alternatives
and select the best one.
66. Decision Making
3. Managers have a purpose in mind
when they make a decision. There
would be no reason for carefully
making a choice among alternative,
unless the decision brings them closer
to the goal.
67. Two types of Decision
1. Programmed Decision
are decision that have been made so
many times in the past that managers
have developed rules for guideline to
be applied when certain situation are
expected to occur.
68. Programmed Decision
programmed decision making are a
routine that you make every time so that
the organization run smooth. Managers
can develop rules and guidelines to
regulate all routine organizational
activities. Most decisions are related to
daily activity.
69. Non- Programmed Decision
are made in response to unusual
opportunities and threats.
this type of decision making does
not need rules or guidelines to be
followed because the situation
unexpected or uncertain.
70. In programmed decision making there will no
error in the decision because it is routine and
managers usually have the information they
need to create rules and guideline to be
followed by other.
Non-programmed decision making are likely
to have an error because it cause more
problems for managers and is inherently
challenging.
71. Major and Minor Decisions
1. Degree of Futurity of Decision
2. Impact of the decision on other
functional areas.
3. Qualitative factors that enter the
decision
4. Recurrences of Decision.
