本文主要研究供应链网络的战略设计问题。我们提出了一个数学建模框架，它同时捕获了网络设计问题的许多实际方面，但在文献中没有得到足够的重视。考虑的方面包括：动态规划范围、通用供应链网络结构、外部材料供应、商品库存机会、商品分配、设施配置、可用于投资的资本以及储存限制。此外，还考虑了有关在规划范围内逐步搬迁设施的网络配置决策。为了应对不断变化的需求，还分析了扩容和缩容场景以及模块化的产能转移。讨论了所提出的建模框架与现有模型的关系。对于合理大小的问题，我们报告了我们使用标准数学规划软件的计算经验。特别是，对各种因素对网络设计决策的影响提供了有用的见解。(C)2004爱思唯尔有限公司。保留所有权利。
In this paper, we focus on the strategic design of supply chain networks. We propose a mathematical modeling framework that captures many practical aspects of network design problems simultaneously but which have not received adequate attention in the literature. The aspects considered include: dynamic planning horizon, generic supply chain network structure, external supply of materials, inventory opportunities for goods, distribution of commodities, facility configuration, availability of capital for investments, and storage limitations. Moreover, network configuration decisions concerning the gradual relocation of facilities over the planning horizon are considered. To cope with fluctuating demands, capacity expansion and reduction scenarios are also analyzed as well as modular capacity shifts. The relation of the proposed modeling framework with existing models is discussed. For problems of reasonable size, we report on our computational experience with standard mathematical programming software. In particular, useful insights on the impact of various factors on network design decisions are provided. (c) 2004 Elsevier Ltd. All rights reserved.
