摘要: 考虑一个传统供应链将市场由单一的实体商店零售扩大到互联网上的在线零售,为满足新增的在线零售需求,供应商需要扩充物流系统的供应容量,并设计新增容量的分配方案。本文针对由一个中心仓库和多个地区仓库组成的二级物流系统,在保留现有配送网络结构的基础上,构建了物流系统的容量扩充与分配模型,并提出一种基于拉格朗日松弛法的求解算法。我们通过数值实验表明了算法的有效性,并通过数值算例说明了运输成本与库存汇聚效应对最优容量扩充与分配方案的影响。

Abstract: When a traditional supplier extends her business from the single channel of in-store retailers to the multi-channel of in-store retailers and e-retailers,she needs to expand her logistics system to supply the new demands from online customers. This paper considers a two-echelon logistics system consisting of a center warehouse and several district warehouses A capacity expansion and allocation model (CEAM) is developed with the structure of current logistics system unchanged.And a Lagrangian relaxation algorithm is designed to solve CEAM. Numerical experiments show the efficiency of the algorithm and illustrate the trade off between transportation cost and inventory pooling effect when searching for the optimal solution.

Key words: multi-channel supply chain, network location, inventory management, E-business
