DEX: An Expert System Shell for Decision Support
نویسندگان
چکیده
An approach to decision making that integrates multi-attribute decision techniques with expert systems is described. The approach is based on the explicit articulation of qualitative decision knowledge which is represented by a tree of attributes and decision rules. The decision making process is supported by a specialized expert system shell for interactive construction of the knowledge base, evaluation of options and explanation/analysis of the results. Practical use of the shell is illustrated by an application in the field of performance evaluation of enterprises.
