Integrated Support Analysis of Military Aircraft Base on Fuzzy Theory
Currently,it has a lot of uncertainty and is difficult to use expert knowledge to integrated support analysis process of military aircraft.This paper took the power system of a military aircraft as example,and created a integrated support analysis model based on fuzzy theory.Firstly,the author used the analytical hierarchy process(AHP)to determine the weight of three different factors which included the historical fault statistics,the analysis results of failure mechanism and the occurrence frequency of fault symptoms,and the influence of three different factors was different to the power system.Secondly,the author processed fuzzily the different failure modes and the present fault symptoms which was obtained by monitoring.On this basis of fuzzily processed,this paper calculated the minimum distance of each specific failure mode which belong to the fuzzy sets of fault symptoms and the membership function of fault mode,and this distance determined the optimal decision scheme.Results showed that the obtained results were consistent with the actual situation,and it proved the effectiveness of the model of fuzzy integrated support analysis and has a good prospects for application.
