集中控制VMITPL模式下的库存运输集成问题

摘要

A supply chain composed of many vendors, one third-party logistics (TPL) , and one manufacturer is addressed. It assumes that, in such a supply chain, it integrates vendor-managed inventory ( VMI) and TPL. For such a supply chain, inventory routing problem under centralized control is studied. How to make the decision of replenishing and vehicle routing plan for suppliers and TPL is a challenging problem. Based on rolling plan period, a new inventory routing model is developed. With the NP-complete nature of the inventory routing problem, a four-step heuristic algorithm based on simulated annealing is presented. The feasibility and effectiveness of the proposed heuristic algorithm is testified by a numerical example.%以“多供应商,单TPL,单制造商”供应链网络为研究环境,研究了集中控制VMI&TPL模式下的库存运输集成优化问题,旨在为供应商和TPL提供补货决策和车辆路线计划.基于滚动计划期,构建了库存运输集成计划模型.鉴于该模型问题是一个NPC问题,提出了基于模拟退火遗传算法的四步骤启发式算法.算例分析结果表明该启发式算法是有效可行的.
