A Design of Expert System for Strategic Decision Making using CBR

Generally, designers appear to solve some problems not by reasoning from the primitive components available in the design domain, but by adapting the design cases of previously encountered artifacts. This paper describes an application of case-based reasoning method to the development of an expert system for strategic decision making. Instead of maintaining only domain specific knowledge for designing a target application, the proposed system, an expert system for strategic decision making (ES-SDM), relies on a case-base that consists of a domain dependent case-base and a domain independent case-base. Whenever a new strategy is designed, it is added to the domain dependent case-base. The strategies for retrieving the relevant cases, for building a rough solution and for learning cases are also described. This system is particularly useful for naive users and experts who use it as a design support tool.
