研究了一类短销售期的变质物品的分销网络设计问题。假定零售商的缺货成本依赖于分配给为其提供服务的分销中心的库存成本,供应商在销售期末给零售商提供第二次订货机会,供应商根据零售商的订货决策确定分销中心的最优选址和确定每个分销中心为哪些零售商提供服务,从而最小化总的运作成本(选址成本,运输成本,库存成本和变质成本),其中分销中心的运输成本和库存成本依赖于零售商确定的订货数量;而零售商则根据供应商的决策确定自身的最优订货决策,利用Stackelberg博弈分析的方法,建立了一类变质物品的分销网络设计模型,并使用拉格朗日松弛算法求解,最后通过数值算例分析了模型最优解对于参数的敏感性。
This paper studies the distribution network design of a kind of deteriorating items with short sales period. Assuming that the retailer’s out-of-pocket costs depend on the inventory cost allocated to the distribution center for which it is serviced, the supplier offers the retailer a second ordering opportunity at the end of the sales period, and the supplier determines the distribution center’s most according to the retailer’s ordering decision Preferred locations and determining which retailers are served by each distribution center to minimize total operating costs (site cost, shipping costs, inventory costs and deterioration costs) where the transportation costs and inventory costs of the distribution center depend on retail While the retailer determines its own optimal ordering decision according to the supplier’s decision, and uses Stackelberg game analysis method to establish a distribution network design model of spoiled goods, and uses the Lagrangian relaxation algorithm Finally, a numerical example is given to analyze the sensitivity of the model optimal solution to the parameters.
