论文摘要
救济用品的预位是灾难运营管理的一个重要方面,旨在通过推进所需供应的采购和存储来减少响应时间。在本文中,我们考虑商品终身期限,并在接近到期时(即持有和拆除成本)时将商品保持在存储中的相关成本。我们开发了一个多阶段的随机编程模型,用于预先定位救济供应,该模型可洞悉如何由于不确定的需求(例如,飓风或地震)发生时如何动态控制库存。我们还提出了一个基于美国大陆的案例研究,以说明拟议模型,并为救济机构提供管理见解。
Pre-positioning of relief supplies is an important aspect of disaster operations management that aims at decreasing the response time by advancing procurement and storage of needed supplies. In this paper we consider commodity life-time period with the related costs in keeping the commodity and removing it from the storage when it is close to expiration (i.e. holding and removal cost). We develop a multi-stage stochastic programming model for pre-positioning of relief supplies, which provides relief agencies insight on how to have dynamically control inventories due to uncertain demands when disasters (e.g., hurricane or earthquake) occur. We also present a case study based on mainland United States to illustrate the proposed model as well as provide managerial insights to relief agencies.
