Study on maintenance, repair and operation strategy of aeroengine enterprise in specific scenarios

Abstract

There are numerous factors influencing aeroengine maintenance, repair and operation (MRO) quality and cost, where their relationship is complicated, and the research focused on maintenance optimization under specific scenarios of aeroengine maintenance enterprises is quite limited. In order to clarify the relationship between the factors affecting maintenance guarantee process, the MRO process is systematically modeled, including main body of procedure, flight time statistics, human resources, performance evaluation and maintenance cost. Two practical application scenarios of enterprise including human resource quality control and performance oriented are investigated by using the principle of system dynamics and grey wolf optimization algorithm assisted by Vensim and MATLAB, which reveals the importance of human resource quality, employee satisfaction and planned maintenance. In consideration of the actual impact of various factors on aeroengine maintenance, the established model and obtained optimal maintenance process strategy is feasible and effective.
