摘要：
In order to enhance the effectiveness of risk evaluation of the aviation maintenance system, multiple connection number theory set pair analysis is proposed, and certain indicators and uncertain indicators in the evaluation system are regarded as a whole. Firstly, the uncertain analytic hierarchy process is introduced to determine the weight interval of evaluation indicators, in which the interval judgment matrix is constructed and expert weight is considered. According to the connection degree expression of three-element connection number, the weight interval of evaluation indicators is converted into the precise weight. Secondly, the uncertain item of three-element connection number is expanded to five-element connection number, and the same-indefinite-contrary model is constructed to assess system risk. Finally, the set pair potential is calculated to judge the risk state of the system. Utilizing the partial connection number, the risk development trend is analysed, which realizes effective combination of static and dynamic evaluation. Through the case study of a maintenance base of airline, the analysis results indicate the adopted method is feasible and effective. © 2016, Chinese Institute of Electronics. All right reserved.
