Problem:
- DSS model for various funcionalities specifically for maintaining attendance by computerized methods and generating reports for top and middle level management
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.
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
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
Components
