2. DSS : DECISION SUPPORT SYSTEM
 A decision support system (DSS) is a computerized system that gathers and analyzes data, synthesizing
it to produce comprehensive information reports.
 Decision support systems allow for more informed decision-making, timely problem-solving, and
improved efficiency in dealing with issues or operations, planning, and even management.
 In organizations, a decision support system (DSS) analyzes and synthesizes vast amounts of data
to assist in decision-making. With this information, it produces reports that may project revenue, sales, or
manage inventory. Through the integration of multiple variables, a DSS can produce a number of different
outcomes based on the company’s previous data and current inputs.

3. CHARACTERISTICS AND CAPABILITIES OF
DSS :
 Support decision makers at all managerial levels .
 Support several interdependent and /or sequential decisions
 Support all phases of decision making and a variety of decision-making processes
and styles
 Can be adapted over time to deal with changing conditions
 Easy to construct
 Utilizes models and links to data and knowledge bases
 Execute sensitivity analysis. ( Sensitivity analysis is the study of the effect that changes
in one or more parts of a model have on other parts of model.)

4. COMPONENTS AND STRUCTURE OF DSS :

5. TYPES OF DECISION SUPPORT SYSTEMS (DSS):
 Text Oriented DSS : contains information in text form allowing documents to be electronically created ,
revised and viewed as needed.
 Data Oriented DSS : Driven by database of organised and highly structured data.
 Spreadsheet Oriented DSS: contains information in spreadsheets .
 Rules Oriented DSS : follows certain procedures and adopted as rules .
 Solver Oriented DSS : based on algorithm or procedure written for performing certain calculations and
executing a particular program type.

• Text Retrieval Systems: Assist decision-makers in retrieving relevant information from large volumes of
textual data, such as documents, reports, and articles.
• Document Management Systems: Organize and manage documents, making it easier for decision-makers to
access and reference information.
 Spatial Decision Support Systems (SDSS):
• Geographic Information Systems (GIS): Incorporate spatial data to support decisions related to geographic
locations. SDSS are commonly used in urban planning, environmental management, and logistics.
 Executive Information Systems (EIS):
• Provide top-level executives with summarized and visually presented information, typically in the form of
dashboards, to support strategic decision-making.
• Enterprise Decision Management (EDM) :
Focus on automating and improving operational decisions within an organization. These systems often
involve rule engines and decision automation to ensure consistency and efficiency in decision-making processes.
Real Time Decision Support System :
Support decision-making in dynamic and rapidly changing environments by providing real-time data and
analytics. These systems are crucial in situations where quick decisions are required.

7. Web Based DSS :
 A Web-Based Decision Support System (Web-DSS) is a type of Decision
Support System (DSS) is delivering decision support information or a tool
to manager and business analyst .
 The computer that is hosting DSS application is linked to user’s computer
via computer networks with TCP/IP.

8. APPROACHES USED TO DELIVER WEB BASED
DSS :
 DATA DRIVEN APPROACH :
Which helps managers to ( organize, retrieve, analysis ) large volume of relevant data
using database and OLAP techniques.
 MODEL DRIVEN APPROACH :
formal representations of decision model and provide analytical support using the tools
of decisions such as
* Decision Analysis
* Decision Simulation
* Decision Statistics

9. FEATURES OF WEB BASED DSS:
1. Web Accessibility: Users can access the DSS through standard web browsers, allowing them to use the
system from various devices, such as desktop computers, laptops, tablets, and smartphones. This
accessibility is particularly beneficial for remote and mobile users.
2. User-Friendly Interface: Web-DSS typically provides an intuitive and user-friendly interface, making it
easier for decision-makers to interact with data, models, and analysis tools. The interface is designed to be
accessible without the need for specialized software installations.
3. Collaboration Tools: Web-DSS often includes features that support collaboration among decision-makers.
This can include real-time sharing of information, collaborative decision-making processes, and
communication tools to enhance teamwork.
4. Centralized Data Management: Data is often stored and managed centrally, allowing users to access and
analyze consistent and up-to-date information. This centralization helps ensure data integrity and reduces
the risk of inconsistencies.
5. Integration with External Data Sources: Web-DSS can integrate with external data sources, APIs, and
other online resources to provide decision-makers with a broader and more comprehensive view of
relevant information.
6. Security Measures: Security is a critical aspect of Web-DSS, and measures are put in place to secure data
transmission, user authentication, and protect sensitive information. This is especially important given the
online nature of these systems.
7. Scalability: Web-DSS can scale to accommodate a growing number of users and increasing data volumes.
This scalability ensures that the system can meet the evolving needs of the organization.
8. Customization and Personalization: Users may have the ability to customize their dashboards, reports, and
preferences based on their specific roles and requirements. This allows for a personalized user
experience.

10. GDSS : GROUP DECISIONS SUPPORT SYSTEM
 GDSS, or Group Decision Support System, is a type of
information system that is designed to support group
decision-making processes. It plays a role in Management
Information Systems (MIS) by facilitating collaborative
decision-making within an organization.

11. 1. Collaborative Decision-Making:
GDSS is specifically designed to assist groups or teams in making decisions. It provides a platform for
members to share information, exchange ideas, and collaborate on the decision-making process.
2. Communication Tools:
GDSS incorporates communication tools such as chat, video conferencing, and messaging to facilitate real-
time interaction among group members. These tools enhance communication and ensure that all members
can contribute to the decision-making process, regardless of their physical location.
3. Information Sharing:
GDSS enables the sharing of relevant information among group members. This can include data, reports,
and other forms of information that are crucial for making informed decisions.
4. Structured Decision-Making:
GDSS often supports structured decision-making processes by providing frameworks, templates, and tools to
guide the group through a systematic approach. This helps in organizing information and ensuring that the
decision-making process follows a logical path.
