基于FAHP的航空维修安全风险管理研究

航空维修对于保障飞行安全至关重要,如何进行航空维修安全风险管理是需要研究的问题.为此应用模糊层次分析法(FAHP),基于"人-机-环-管-接口"的理论,研究了影响航空维修安全的各种影响因素.利用三角模糊数并通过专家判断来构建三角模糊互补判断矩阵.按照层次结构模型和模糊层次分析法的步骤,对各影响因素进行了层次单排序和总排序,并把结果进行了分级和排序.结果表明,影响维修安全的主要因素为企业的规章制度、安全文化和维修人员的惯性违章等航空维修应该重点改善这3个因素并兼顾其他影响因素.研究表明,模糊层次分析法有助于确定安全风险管理的重点.

Risk management for aviation maintenance safety based on fuzzy analytical hierarchy process

This paper is aimed at presenting the results of applied research of the fuzzy analytical hierarchy process in risk management of aviation maintenance. For our research purpose, we have adopted fuzzy analytical hierarchy process which is based on triangular fuzzy number. Fist of all, we have constructed a hierarchical structure model, in which we have consulted "man-machine-environment-management" system theory and combined SHEL model theory. At the same time, we have developed a model based on "man-machine-environment-management-connection". Secondly, we have given the fraction based on aviation experts' judgment and constructed six triangle fuzzy number complementary judgment matrixes, according to which, we have worked out a row sum of matrixes while gaining the triangular fuzzy number proportional vectors and probability matrix. By using the above results, we have performed single hierarchy taxis and competitive taxis. Then, taking an aviation maintenance company as a case study sample, we have done experiments to break the aviation maintenance safety system into several actual manageable aspects so that the company could be effectively evaluated and calculated in accordance with the actual situation of the company by using the fuzzy analytical hierarchy process. In conclusion, we have to point out that the weak aspects of the aviation maintenance safety management be recommended with available measures as well as the classified and categorized factors to be improved. The main factors are the regulations and safety culture and inertial infringement of the company. Thus the analysis conclusion indicates that the factors which affect the aviation maintenance safety could be identified objectively and effectively improved by using fuzzy analytical hierarchy process, which proves to help to confirm the keystone of the company when safety risk management is performed.
