摘要

首次建立起PMC方程模型的定义(即PMC模型的方程描述).PMC模型是一种最常见的系统级故障模型

针对传统的图论诊断算法离不开"

-可诊断性"和"相信大多数"(即假定系统中故障机的台数少于处理机总台数的一半)的特点

文中引入"绝对故障基"等概念

并充分运用"集团"工具

在不以"

-可诊断性"和"相信大多数"作前提假设的情况下

找到了求PMC模型全体相容故障模式的具体方法——方程诊断算法.

Abstract

The definition of PMC equation model (that is equation description of PMC model)was first set up.PMC model is a kind of most common system-level fault model.Owing to the characteristics that traditional graph theory diagnosis algorithm couldn't be without "

-diagnosabe" and "believe the most" (that is supposing the number of fault processors less than half the number of all processors in the system)

the concepts of "absolute fault base"etc.were defined

and the tool of "body grouping"was fully wielded

finally a concrete method——equation diagnosis algorithm was found

on seeking all consistent fault patterns for the class of models without supposing "

-diagnosable" or "believe the most".
