Abstract

This paper introduces a set of comprehensive general reasoning rules about single faults based on a diagnostic matrix. The reasoning scheme unifies inference about faults based on a conventional binary diagnostic matrix, a two- and three-valued fault isolation system as well as on their fuzzy counterparts. There are introduced and defined notions of alternative and dominant fault signatures, fuzzy fault signatures as well as a matrix of alternative signatures. This matrix is supposed to be used instead of the classic diagnostic one. It is also shown that dominant fault signatures are transformable into alternative ones. Finally, three variants of concise general reasoning rules of faults are given. Three examples illustrate key point issues of the paper. The first example refers to a medical diagnostic case. It shows an instance of dominant fault signatures and, in fact, proposes a rational approach for planning diagnostic tests. The other examples describe the fuzzy reasoning approach employing a matrix of fuzzy alternative signatures applicable for use with multi-valued fuzzy diagnostic signals. Future works are outlined in the summary section.
基于诊断矩阵的故障广义推理
介绍了一套基于诊断矩阵的单故障综合通用推理规则。该推理方案将传统的二值诊断矩阵、二值和三值故障隔离系统及其模糊对应系统的故障推理统一起来。引入并定义了备选和主导故障签名、模糊故障签名以及备选签名矩阵的概念。这个矩阵应该被用来代替经典的诊断矩阵。研究还表明,优势断层特征可以转化为替代断层特征。最后,给出了简明的故障一般推理规则的三种变体。三个例子说明了本文的重点问题。第一个例子是一个医疗诊断案例。它显示了一个主要故障特征的实例,实际上,提出了一种合理的方法来规划诊断测试。其他示例描述了采用适用于多值模糊诊断信号的模糊替代签名矩阵的模糊推理方法。在总结部分概述了未来的工作。
