Service Parts Logistics (SPL) is a part of supply chain management that refers to providing after-sales service (e.g. providing parts and necessary repair on-site upon the breakdown of network servers, medical equipment, or aircraft). SPL industry is currently worth $1.5 trillion worldwide with major sectors growing at 15-20% annually. The major challenge in operating an SPL network is to guarantee a highly responsive service to customers in need (usually within few hours of customer's request). The problem is further complicated by the presence of multiple classes of customers and their quality of service guarantees. The increasing variety of parts and the uncertainty in their demand add to the complexity of the planning process. Furthermore, shrinking life cycle of many products results in a proliferation of parts with infrequent demands. As a result of these conflicting objectives, there arises a number of challenging problems in SPL systems such as designing a network of part stocking facilities, planning inventory ordering policies, and dispatching the required parts from the facility within the manufacturer's network to geographically distributed customers in need. The goal of the proposed program is to develop a variety of mathematical models and solution approaches to understand the interaction and the interdependencies of the network design and inventory decisions in SPL systems. The results and insights from this research will act as a useful decision support tool for the managers in industrial settings, as well as non-commercial enterprises such as the military, in designing and managing their SPL network efficiently.

备件物流是供应链管理的一部分，指的是提供售后服务(例如，在网络服务器、医疗设备或飞机发生故障时，现场提供零部件和必要的维修)。SPL行业目前在全球范围内价值1.5万亿美元，主要行业以每年15%-20%的速度增长。运营SPL网络的主要挑战是保证对有需要的客户提供高度响应的服务(通常在客户请求后的几个小时内)。多类客户的存在及其服务质量保证使问题变得更加复杂。零件的种类越来越多，需求的不确定性增加了计划过程的复杂性。此外，许多产品生命周期的缩短导致了需求不多的零部件的激增。由于这些相互冲突的目标，在SPL系统中出现了许多具有挑战性的问题，例如设计零件库存设施的网络，规划库存订购策略，以及将所需的零件从制造商网络内的设施分派给需要的地理分布的客户。该计划的目标是开发各种数学模型和解决方案，以了解SPL系统中网络设计和库存决策的相互作用和相互依赖关系。这项研究的结果和见解将为工业环境中的管理者以及军事等非商业企业有效地设计和管理其SPL网络提供有用的决策支持工具。
