通用减速器设计专家系统中解释策略的研究

THE STUDY OF EXPLANATION STRATEGIES IN THE INTELLIGENT AUTOMATIC DESIGN OF GENERAL GEAR BOX

解释是专家系统的重要特征之一。解释不仅能增加系统的可接受性,而且能辅助知识库的建立,以及将专家系统用于教育。随着专家系统技术的发展,人们对系统的透明性越来越重视,对系统解释能力的要求也越来越高。本文首先探讨了透明性在专家系统中的地位及专家系统对解释技术的要求,然后对通用减速器设计专家系统中所采用的解释方法——预制文本、执行追踪法以及更高层次的策略解释法进行了较为详细的研究。

Explanation is One of the important features of expert Systems. It can be used not only to increase the acceptability and to aid the building of expert systems, but also to educate users. With the development of expert System techniques, transparency and the requirements of explanation capabilities are increasingly paid attention to. In this paper, the position and the requirements of transparency are first studied. Then the explanation strategies Canned Text, Excution Traces and Strategical Explanation, used in the intelligent automatic design of general gear box are studied in detail.
