基于案例推理的压力容器故障维修方法
Fault Maintenance Method of Pressure Vessels Based on Case Reasoning
摘要
Abstract
By the problems of pressure vessels fault with high dependence on empirical knowledge and low utilization ratio of intelligent knowledge base,the method of pressure vessels fault was put forward based on case-based reasoning.According to the definition of fault characteristics keywords dictionary and the optimization of case storage and indexing mechanism,the case information was structured and better educated.And using a combination of nearest-neighbor method and gray case similarity algorithm to improve the accuracy of case matching,it was better for giving the similar pressure vessel fault a reference.Verified by the application examples,it was faster and more reliable to match the similar cases from the case base,and it could be used for reference to the original fault case.The method effectively reduces the dependence on empirical knowledge,and better uses the intelligent knowledge base,which provides convenience for the whole life cycle of the pressure vessel MRO.关键词
