摘要
针对医药供应链物流系统,分析了药品供应链物流的需求特征,阐述了药品供应链中生产企业、批发企业构建共享物流中心的意义,提出了一种三方合作效益最大化的物流联盟结构模式。建立了药品物流联盟物流中心节点选址的双层规划模型,上层规划以联盟效益最大化为目标,下层规划考虑联盟博弈的Shapley分配模式,体现了各参与方的利益分配最大化,并设计了遗传算法的求解模式。算例测试结果表明,该方法与算法具有较强的实践可操作性,可以作为物流节点选址决策的参考方法。
For the logistics system of medicine supply chain,it analyzed the demand character of medicine supply chain logistics,explained the significance about building the shared logistics center between production enterprises and wholesale enterprises in the medicine supply chain.This paper proposed a structure mode of logistics alliance which can embody the maximum benefit under the cooperation of the three party.It established a bilevel programming model for the location of logistics center of medicine logistics alliance,the object of upper planning is maximum alliance benefit,and the lower planning considered the distribution model of Shapley based on alliance game,which reflected the maximum distribution interest of each party.Lastly it designed the solving model of genetic algorithm.The result of a tested example shows that the practical operability of the method and algorithm is more effective,and it is a reference method for deciding the location of logistics nodes
