Research on Fusion Method of Prior Information in Maintainability Test

摘要

In order to solve the problem of low precision of prior information fusion caused by different data population in maintainability test, the conversion model of prior information was proposed based on the availability of information, the problem of unable to fuse the information because of different data population was solved. The parameters of prior distribution were fitted by random weighting method, prior distribution was described exactly. Weight determination method based on the degree of support was proposed, and the reasonability of weighting fusion was improved. Finally, the engineering application value of the fusion method proposed by this thesis was proved by the information fusion instance of a certain equipment in maintainability test.
