- Abstract:
-
This paper establishes a dynamic maintenance resource optimization scheduling model of multi-supply centers and multi-demand points in different combat stages to solve the problems of inaccurate prediction and resource conflict in the process of maintenance resource scheduling. Therefore, multiple supply centers can timely and efficiently schedule maintenance resources at demand points. The model reduces the resource scheduling time and the unsatisfying amount of maintenance resources at each demand point. An improved multi-objective evolutionary algorithm is proposed in this paper to solve the proposed model effectively. The co-evolution strategy of the normal distribution crossover operator, global exploration enhanced differential evolution operator, and adaptive mutation operator is used to improve the local search capability and population diversity of the algorithm based on the classical MOEA/D algorithm. Simulation results show that the proposed algorithm has good convergence and distribution uniformity and has high solution efficiency.
