专家系统中的一种两级不确定性推理模型

A Two-Leveled Uncertainty Reasoning Model for Expert System

本文简单介绍了专家系统中的一种两级不确定性推理模型LTCSR.在LTCSR 中,采用两级不确定性度量(信度、可靠度)来表示事实及知识的不确定性.LTCSR 已用于我们研制的油局部圈闭评价专家系统中.从已运行的实例来看,其结果与领域专家观点吻合.

A two-leveled uncertainty reasoning mod-el LTCSR for expert system is describedbriefly in this paper.In LTCSR,the uncer-tainties of fact and knowledge are expres-sed by two-leveled uncertainty measure-ment(certainty,reliability).This reasoningmodel has been applied to an expert systemfor the oil local trap comment,as the coreof this system.The system is on trial withinstance at present,and the results fromthe instance are perfectly consistent withthe views of domain experts.
