Abstract
The purpose of this paper is to design the conceptual framework for the intelligent decision support system(IDeSS-SP) which supports decision makers to plan their strategies. Firstly this paper describes that the ideas of system development for DSS and the techniques of artificial intelligence play important roles in developing IDeSS-SP. Secondly it analyzes the characteristics of strategic decision and formalizes its decision as a problem of AI. Finaly it analyzes the functions of IDeSS-SP and designs the framework of the system which is basically organized by the learning system, the decision system and the production system.
