Abstract:

To deal with the problem of heavy repair tasks, limited repair time and complicated constraints in wartime, the multi-objective dynamic scheduling of the wartime equipment maintenance tasks for fixed-point repairing is studied. The military problem of wartime fixed-point repairing maintenance task scheduling is proposed. Considering the constraints of repair time window and non-traversal, a multi-objective dynamic scheduling model of the wartime equipment maintenance task is constructed. The step-by-step solution is adopted to deal with the two-stage optimization problem of repair team allocation and repair task sorting. The max-min ant system (MMAS) algorithm is improved from three aspects: state transition rule, pheromone update rule and a priori information acquisition. The local search of the variable neighborhood search (VNS) algorithm is combined with the enhanced algorithm. Based on the ability, the model solving algorithm based on Pareto improved VNS-MMAS is designed. Through example simulation and analysis, the rationality and effectiveness of the model and the algorithm are verified.

Key words: fixed-point repairing, multi-objective, dynamic scheduling, repair time window
