Problem oriented analysis and decision expert system
面向问题分析与决策的专家系统

The ultimate goal of the expert system is to provide strong ability of analysis and decision for the practical problems.Based on the problem analysis and decision thought got by human for long practical activities,this paper showed a problem oriented analysis and decision expert system which used problem objects as core,correlated objects as problem meta-objects,problem phenomena as expression form,causalitied as problem transformation driver,procedure knowledge and principle knowledge as reference object.The knowledge base of the expert system is built around the application problems without using the rules,so the system is more rational and clear,and is not easy to generate the knowledge conflicts and is convenient to build large scale knowledge base.At the same time,problem based inference is used in this system,which accords with the human thinking habits and has higher inference efficiency.Moreover,domain experts can develop this kind of expert systems without mastering artificial intelligent language and needing the participation of knowledge engineers,and only concentrate on the analysis and codification of the domain-specific knowledge completely.
