基于主从博弈的装备维修器材供应链协调订货

Supply Chain Coordination Ordering in Equipment Repair Equipment Based on Stackelberg Game

为了减小维修单位的库存压力,提出一种基于Stackelberg主从博弈的装备维修器材供应链协调订货机制。结合装备维修器材供应现状,供应商作为主方提出最小补充期策略和数量折扣,维修单位作为从方以最佳订货策略响应,以供应商成本最小化为目标建立优化模型,构建带有惩罚因子的特殊适应度函数,利用粒子群优化算法进行求解,并运用军事算例进行仿真。仿真结果表明:该机制不仅可以降低整个供应链的成本,也可以使其成员有不同程度的收益。

For reduce inventory overstocking of maintenance unit, put forwards equipment maintenance parts supply chain coordination ordering mechanism based on Stackelberg game. Combined with the supply situation of equipment maintenance parts, the suppler, which is the host, introduces the minimum replenishment periods strategy and quantity discount, the maintenance unit, as the service part, introduces the optimal order strategy. Based on suppler minimize cost as target, establishes optimal model, constructs special fitness function with punishment factor, uses particle swarm optimization （PSO） algorithm to carry out resolution, and takes military example to simulate. The simulation results show that the mechanism can not only reduce the cost of the whole supply chain, but also can make the members of different levels of income.
