Decision Support System

Decision Support System

1. Problem:

   • DSS model for various funcionalities specifically for maintaining attendance by computerized methods and generating reports for top and middle level management

2. Concept:

   • A Decision Support System (DSS) is an interactive, flexible, and adaptable computer based information system that utilizes decision rules, models, and model base coupled with a comprehensive database and the decision maker’s own insights, leading to specific, implementable decisions in solving problems that would not be amenable to management science models.

3. Characteristics

   • Handlelarge amounts of data like database searches
   • Obtain and process data from different sources
   • Provide report and presentation flexibility
   • Have both textual and graphical orientation like charts, trend lines, tables and more
   • Perform complex, sophisticated analysis and comparisons using advanced software packages
   • Perform "what-if" and goal-seeking analysis

4. Capabilities

   • Support for problem-solving phases
   • Support for different decision frequencies that range from one-of-a-kind
   • One-of-a-kind decisions are handled by an ad hoc DSS
   • Repetitive decisions are handled by institutional DSS
   • Support for different problem structures ranging
   • Support for various decision-making levels

5. Components

   • Data Management subsystem
   • Model Management subsystem
   • Knowledge-based Management subsystem
   • User Interface subsystem

6. Design and development

   • Prototype method
   • Life cycle approach
