Purolator, a Canadian company offering express package delivery services, has to improve its operations on a continuous basis in order to satisfy its customers, while maintaining its efficiency in the face of ever-growing challenges such as fierce competition and the expansion of e-commerce services. The company is particularly interested in the analysis of alternative ways to perform its operations that would reduce its costs, while improving its quality of service. These alternative approaches would involve reconfiguring its current network of facilities. This six-month Engage project is a first step in this direction. We will focus on the local area network of Montreal. We will first analyze the demand using data from the last years made available to us by the company. This will allow us to characterize trends over space and time (within each week and within each year) and to identify opportunities for better usage of the available capacity. We will assume that there is only one regional hub with a known location and a number of existing terminals. As part of the Engage project, we will analyze scenarios that involve reconfiguring the terminals, specifically closing some of them and relocating their operations to the hub or to other terminals. To this end, we will develop a mixed-integer programming model representing the facility location decisions in a "flexible" hub-and-spoke network, where terminals can be closed and their operations relocated.

Purolator 是一家提供快递包裹递送服务的加拿大公司，该公司必须改善其运营 不断满足客户需求，同时在不断增长的情况下保持效率 激烈的竞争和电子商务服务的扩张等挑战。该公司特别 对分析可降低成本的替代运营方式感兴趣，同时 提高其服务质量。这些替代方法将涉及重新配置其当前网络 的设施。这个为期六个月的参与项目是朝这个方向迈出的第一步。我们将专注于当地 蒙特利尔网络。我们将首先使用过去几年向我们提供的数据来分析需求 公司。这将使我们能够描述空间和时间上的趋势（每周内和每个内） 年）并确定更好地利用可用容量的机会。我们假设只有 一个具有已知位置和多个现有航站楼的区域枢纽。作为参与项目的一部分，我们 将分析涉及重新配置终端的场景，特别是关闭其中一些终端， 将其运营转移到枢纽或其他航站楼。为此，我们将开发一个混合整数 代表“灵活”中心辐射网络中设施位置决策的编程模型，其中 航站楼可以关闭并重新安置其运营。
