Abstract:

In order to improve the maintenance support efficiency and support personnel availability of multi carrier aircrafts effectively, according to the constraint characteristics of maintenance support process for single carrier aircraft, a multi objective integrated maintenance support scheduling model of multi carrier aircrafts based on multiple program evaluation and review technique networks is established. To solve the problem, a self-adaptive hybrid differential evolution algorithm is presented. First, a decoding method based on event scheduling is designed according to networked queuing process of scheduling. Second, for coordinating the exploration and exploitation in algorithm, a self-adaptive mutation operation, an adaptive control strategy of crossover and mutation parameters are introduced. Third, in view of the characteristics of parallel arrangement of process blocks, four kinds of neighborhood structure are defined, and then a novel local search based on the newly defined neighborhoods is presented and imbedded in the SaHDE algorithm. The simulation results show the feasibility of the model and the effectiveness of the algorithm.
