The increased complexity of modern manufacturing and supply chain networks has drawn attention to the importance of logistics and transportation in engineering. Logistics deals with the efficient flow of goods from their points of production to their points of consumption. It involves the integration of several activities such as inventory, transportation, warehousing, and material handling. Among these activities, transportation is the most important in terms of costs and plays a crucial role in the social, political and economic activities of a country. For instance, in Canada the transportation industry accounted for 4.7 % of the GDP in 2009 and thus, contributed $55.8 billion to the economy (see Statistics Canada). Many companies are thus turning their attention to the optimization of their logistics and transportation networks to ensure that the products are delivered at the right time, in the right place, and at the least possible cost. The aim of this research program is to further the study and development of integrated models of facility location and network design, which lie at the heart of strategic design planning in transportation systems, namely in the airline and trucking industries. This type of decision models are also of vital interest to telecommunication firms, given the explosive growth of modern computer and voice communication networks. An important part of this program will focus on the study of new network hub location models that incorporate additional features of real applications such as congestion and reliability issues, the effects of uncertainty of demands and transportation costs, and the relaxation of classical assumptions. These hub networks are widespread used by international and national airline companies such as Air Canada, Air Transat, and WestJet. Network hub location is also a central problem for many express delivery and post operator companies such as FedEx, UPS, and Canada Post Corporation. This research program has the potential to make substantial contributions to the solution of complex problems of high practical relevance. It will also contribute to the development of innovating methodologies in the general fields of operations research and optimization.

现代制造和供应链网络的日益复杂，引起了人们对物流和运输在工程中的重要性的关注。物流处理的是货物从生产点到消费点的有效流动。它涉及到诸如库存、运输、仓储和物料处理等活动的整合。在这些活动中，交通运输在成本方面是最重要的，在一个国家的社会、政治和经济活动中起着至关重要的作用。例如，在加拿大，2009年运输业占国内生产总值的4.7%，因此为经济贡献了558亿美元（见加拿大统计局）。因此，许多公司将注意力转向优化其物流和运输网络，以确保产品在正确的时间、正确的地点以尽可能低的成本交付。本研究计划的目的是进一步研究和开发设施选址和网络设计的综合模型，这是运输系统战略设计规划的核心，即航空和卡车运输业。考虑到现代计算机和语音通信网络的爆炸性增长，这种类型的决策模型也对电信公司至关重要。该计划的一个重要部分将集中于研究新的网络枢纽位置模型，该模型结合了实际应用的附加特征，如拥堵和可靠性问题，需求和运输成本不确定性的影响，以及经典假设的放松。这些枢纽网络被国际和国内航空公司广泛使用，如加拿大航空公司、越洋航空公司和西捷航空公司。网络枢纽的位置也是许多快递和邮政运营商的中心问题，如联邦快递、UPS和加拿大邮政公司。该研究项目有潜力为解决具有高度实际意义的复杂问题做出实质性贡献。它还将有助于在运筹学和优化的一般领域的创新方法的发展。
