Uncertainty Reasoning of Mode Diagnosis for 0Cr18Ni10Ti Pipe Corrosion Failure

College of Naval Architecture and Power, Naval University of Engineering, Wuhan, 430033, China

摘要: 通过归纳0Cr18Ni10Ti管道腐蚀失效案例与失效分析的经验,总结出失效诊断需要着重考虑的信息特征;提出产生式与框架式相结合的失效知识表示方法以及失效规则权重的确定方法;提出规则带置信度因子的加权不确定推理方法,并对诊断推理中的计算问题进行了实例说明。

Abstract: Based on the summarization of failure cases and experience of 0Cr18Ni10Ti pipe,the features of corrosion failure information to be considered are generated.Uncertainty knowledge presentation methods which combines production and frame are devised,and the method for acquiring weights of features in corrosion failure rules is presented.The uncertainty reasoning method of weighted of failure rules is presented,and an example of calculation in diagnosis reasoning is illuminated.The research is the foundation of intelligent diagnosis of corrosion failure mode.
