多属性选择专家系统的启发式策略

Heuristic Strategies used in a Multi-Attribute Selection Expert System

在许多场合,诸如设计、测试等领域都会遇到与多个属性相关的选择问题.我们研制了一个用于解决多属性选择问题的专家系统,其作法是以多属性效益量度的评优函数为基础,采用了启发式的选择策略将属性要求与评优分值有机地结合起来帮助用户决策.在选择过程中,利用了用户反馈来自动调整评优函数的评价机制.

Select problems relating to multiple attributes occur frequently in many fields,such as design,test,etc. We have developed an expert system to tackle the multiattribute selection problems. This system is based on a merit function for multi- attribute utility measurement. Heuristic strategies are utilized to combine organically the attribute requirement with the merit score to help users to make decision. During the selection, the evaluation mechanism of the merit function would be regulated automatically according to the user' s feedback.
