(1) A method has been developed to divide a objective plant into seguments where fault diagnosis can be made without exchange of information on other segments(2) A signed digraph has been made for a mini-plant composed of pipelines and tanks simulating reactors with jacket and has been divided into segments by use of the above method.Distributed fault diagnosis systems have been designed corresponding to the individual segment.(3) The performances of the distributed fault diagnosis systems were examined from the view points :(a) speed of diagnosis(b) accuracy of diagnostic results(c) responsibility of diagnostic resultsby fault diagnosis experiments in 22 abnormal states from different origin of failures.Differences of performances by used algorithms were also examined for the following ones :(1) Original algorithm utilizing the signed digraph(2) Algorithm utilizing weighted signed digraph(3) Algorithm utilizing weighted signed digraph with conditional branches

(1)提出了一种将客观电站划分为多个分段的方法，在不交换其他分段信息的情况下进行故障诊断。(2)对一个由管道和储罐组成的模拟带夹套反应堆的小型电站进行了有符号有向图的绘制，并利用上述方法将其划分为多个分段。针对各个分段设计了分布式故障诊断系统。(3)通过对22种不同故障来源的异常状态进行故障诊断实验，从诊断速度(b)诊断结果的准确性(c)诊断结果的可靠性等方面考察了分布式故障诊断系统的性能。研究了不同算法在以下方面的性能差异：(1)使用有符号有向图的原始算法(2)使用加权有符号有向图的算法(3)使用带条件分支的加权有符号有向图的算法
