Research of CRB based on grey-relation analysis and its application in aviation fault diagnosis

摘要

As large amount of fault diagnosis and aviation maintenance experience is accumulated during the maintenance of procession, this paper, based on CRB (Case-Based Reasoning), discusses the structure, expression, retrieval, and maintenance of the aircraft fault case base, particularly, it brings grey-relation theory into the calculation of fault case similarity. According to experiment result, the new method improves the accuracy and efficiency of fault case mapping, as well as_the distinguishability. At last, a prototype system and the major flow is proposed.
