Abstract:

To deal with the fact that the existing wartime spare parts scheduling model is not flexible enough, ignores the priority sequencing of demand points, only handles a single type of spare parts, and has a low algorithm operation efficiency, a multi-objective spare parts scheduling method in wartime considering lateral transshipment and emergency distribution is proposed. On the basis of the traditional forward scheduling model, lateral transshipment and emergency distribution strategies are added, and a wartime spare parts scheduling model that simultaneously handles multiple types of spare parts is established with the objectives of the smallest number of missing parts and the shortest transportation time. A priority sequencing method for demand points based on the technique for order of preference by similarity to ideal solution (TOPSIS) is formulated, and the multi-objective evolutionary algorithm based on decomposition considering priority sequencing (MOEA/D-PS) is designed to solve the model using the framework of the multi-objective evolutionary algorithm based on decomposition (MOEA/D). The results show that: the scheduling model considering lateral transshipment and emergency distribution has the best support effect; the MOEA/D-PS algorithm can satisfy both the solution quality and the computational efficiency, and the average CPU running time is 62.86% shorter than the non-dominated sorting genetic algorithm II (NSGA-II); in addition, the priority sequencing and the required time limit significantly affect the effectiveness of spare parts supply support.
