Decision support system: An activity-oriented design

Abstract

Decision Support Systems (DSSs) have been defined in a number of ways by various researchers. The result is disagreement and confusion. No one is quite sure of its exact definition.In this research, we have tned to redefine it by asking two basic questions: What things to support and how to support them? It is argued that critical activity analysis is a preferable starting point for a DSS design, and a DSS needs to support activities rather than decisions. A tool-kit framework for a DSS is presented for its design. Finally, a case study application is described where such a framework has been implemented in APL.

“…An example of a typical problem definition and the solution plan is given in Section 5.2. In Ittools integration" we focus on a "collection of tools" [Sen, 1983;Sen and Biswas, 19851 [Donovan, 1976;Heltne et al, 19881. Transportability ensures that the DSS remains problem-domain independent.…”
