Safety Performance Evaluation for Civil Aviation Maintenance Department

Abstract

The MMEM model and the core risk analysis method are applied to construct the safety performance index system of the civil aviation maintenance department, and four categories of the safety performance indicators are set up, including maintenance error, aircraft condition, safety foundation and safety management. In order to take into account the different effects of subjective and objective weights, the comprehensive evaluation model based on the subjective and objective combination weight method for the safety performance of the airline maintenance department is established. The analytic hierarchy process and entropy method are used to calculate the subjective weight and objective weight of the index respectively, and the optimization theory is used to calculate the combination weight of the index. The data from 2011 to 2016 in a maintenance department of an airline is used as an example of application, and the results of the evaluation are analyzed. The results show that the proposed safety performance evaluation model can quantitatively reflect the safety state of the maintenance department and the evaluation results are reasonable.
