The Key Parts' Maintainability Evaluation Of Panzer Equipment Based On Similar Information Fusion

Maintainability is one of the most important characteristics of panzer equipment. Evaluating the maintainability level, on the one hand, we can prove whether the maintainability of the panzer equipment fulfill the requirements of users. On the other hand, it makes the designers know the maintainability level, differentiate the design limitations and improve them. And the maintainability level of the key parts directly influence on the equipment's, then on the battle effectiveness of equipment formed. So it is necessary and important to research on the key parts'evaluation. This paper aims at the problems of small sample in evaluating, and fuses the similar information using multisource information fusion technique. The main researches of the paper are as follows.Introduces the maintainability indices and parameters of panzer equipment, and the traditional methods of GJB, then analyses the limitation.Provides the fusion method of the parts'same maintainance information.Through compatibility test, confidence analysis, fusion weight confirming, we get the prior distribution, then we use Bayse finish the work.Provides the fusion methods of the parts'similar maintainance information.Using hierarchical Baysian method, kullback information method, maximum entropy method, goodness-of-fit method and similarity method and so on, we get the prior distribution, then we also use Bayse finish the work.In the end, we prove the methods are useful by researching on an example.
