引入了JITD思想,对分销网络中的总库存进行统一集成运作,考虑了配送的准时性和稳定性,并从物流系统集成的高度出发,研究建立了确定需求下多设施多顾客的集成设施选址——运输路线安排——库存控制问题(ILRIP)模型,设计了一个两层粒子群优化(PSO)算法,并给出了计算实例。研究结果有助于优化物流分销网络结构,提高顾客服务水平以及交期可靠度、降低成本。
The theory of Just in Time Distribution(JITD) is applied into the distribution network design.By coordinating the whole inventory of network,considering the punctuality and stability of distribution,a model of Integrated Location Routing and Inventory Problem(ILRIP) is built on the condition that the demand is fixed and there are many distribution centers and customers from the perspective of integrated logistics,then a bi-level algorithm of Particle Swarm Optimization(PSO) is designed to solve it.At the end of this paper,a numerical example is given.The conclusion will help to optimize the logistics distribution network,so as to improve the reliability of quick response and the customer service level,as well as reduce cost.
