Abstract: A multi-objective optimization model is established for multi-item maintenance material distribution to help the supply centers satisfy the maintenance material demands of troops. In the proposed model, the priority, fairness and efficiency are taken as the multi-objects. An improved genetic algorithm is combined with grey correlation degree method, which can transfer multi-objective problem to single-objective problem. The example verification shows that the best and mean fitness values are reduced by 31.538 5% and 37.371 1%, respectively. The proposed model can be used to reduce the unfairness of multi-item maintenance material distribution, and improve the efficiency of materials supply. Key
