基于串件拼修策略的工程装备备件库存控制

Study of engineering equipment spare parts inventory control based on cannibalizing strategies

工程装备备件精确保障是未来工程部队工程装备保障的改革和发展方向,搞好工程装备备件库存是实现工程部队装备备件保障精确化的重要保证。分析了当前工程装备备件保障的相关理论和发展趋势,指出了其弊端。研究了工程部队工程装备备件维修和库存特点。为了更好地提高工程装备备件保障效率,引入了串件拼修理论,并指出了串件拼修的适应性及其优点,然后分别建立了单个工程基地库存模型和工程部队两级联合库存模型,最后通过实例对比分析表明:该方法优于传统的备件库存理论和无串件拼修的备件库存模型,能够显著节约备件保障成本。

It is a direction of reform and development for the engineering force to provide a forceful support for equipment spare parts. Doing the engineering equipment spare parts inventory control well is the important guarantee of the engineering force implementing a precise inventory control. The re lated theory and developments were analyzed, and their defects were pointed out and the maintenance and inventory characteristics of the air force equipment were investigated. In order to enhance the efficiency of spare parts support, the cannibalizing theory was introduced for analyzing its advantages and adaptability. Then, an inventory model and a two-level joint inventory model of a single air force base were established respectively. Finally, the analysis and comparison of some examples show that this method is better than the conventional spare parts inventory theory and the non-cannibalizing spare parts inventory model, and can save the cost of supporting spare parts significantly.
