时态外推推理诊断模型

A DIAGNOSTIC MODEL BASED ON TEMPORAL ABDUCTIVE INFERENCE

本文通过引入时态一致覆盖集的概念,提出一个基于时态推理与覆盖技术的时态外推推理诊断模型TGSC.TGSC利用模糊集描述有关征兆、故障及相互间关系的时态知识,文中建立了TGSC的基本框架,给出了基于假设图搜索的诊断问题的求解方法,并给出计算示例。

By introducing the concept of temporal consistent set covering, a diagnostic model named TGSC based on temporal reasoning and set covering is proposed in this paper. TGSC uses fuzzy sets to describe temporal information about disorders, manifestations and relations between them. The basic framework of TGSC is built, the diagnostic problem solving method based on hypothesis graph searching presented, and an example is given.
