摘要: 在装备可维修备件的多级库存系统中增加横向供应策略,将传统的树状备件供应模式扁平化,可以大大缩短备件平均延误时间。在此背景下进行多级可维修备件的库存研究,建立具有横向供应策略的可维修备件两级库存模型,利用M/M/∞排队系统评估备件满足率、横向供应概率和缺货概率等重要参数,设计启发式算法进行备件优化配置。算例结果表明,引入横向供应策略后可维修备件两级库存系统的保障总费用能够降低39.4%.

Abstract: Multi-echelon spare parts inventory systems with lateral transshipments make the traditional tree-like supply mode become a flat structure, which can shorten the average waiting time of spare parts. The multi-echelon spare parts inventory system is analyzed to build a multi-echelon spare parts inventory model with lateral transshipments, and the related important parameters, including spare fill rate, lateral transshipment probability and probability of shortage, are evaluated based on M/M/∞ queue model. A heuristic algorithm is used to minimize system-wide spare parts. The experiment shows that the two-echelon support cost with lateral supply can be reduced by 39.4% by introducing the lateral supply strategy.

Key words: operations research, repairable spare part, lateral transshipment, two echelon inventory system
