Available in PDF, EPUB and Kindle. Book excerpt: This dissertation addresses problems arising in freight routing and scheduling where full truckload (FTL) and less-than-truckload (LTL) carriers are used to serve transportation needs. Each of the problems investigated in this dissertation tries to optimize/maximize consolidation to decrease system transportation costs by (1) carefully choosing the timing and path of freight and/or (2) introducing consolidation points. Approaches are proposed that enable effective planning and operation of freight routing and scheduling for large-scale transportation networks. Chapter 2 presents solution approaches for a shipper pickup and delivery planning problem faced by many large retailers to move freight from suppliers to distribution centers. Each shipment is moved either direct via a LTL carrier or possibly consolidated with other shipments and moved by one or two FTL routes. When using a FTL carrier, the shipper takes advantage of contracted lane rates that establish prices per mile for a truck operated between two locations that are significantly less than the comparable LTL price for shipping a full truckload. Consolidated FTL routes may each visit multiple shipment origins (supplier locations) and/or destinations (distribution center locations). Additionally, FTL routes may move shipments through a single crossdock facility en route. The challenge in this planning problem is to exploit as much as possible negotiated truckload lane rates and to judiciously make use of routes through crossdock facilities to consolidate shipments. The primary contributions of this section are that (1) an interesting new problem variant is introduced to the field of transportation and logistics that is important in practice and (2) the solution approach demonstrates that exploiting knowledge of the problem and solution structure to cleverly select subsets of path variables for evaluation during each iteration of an integer programming based local search heuristic is effective on path-based routing models. Chapter 3 evaluates how to route each customer shipment through a sequence of transfer terminals in a LTL carrier network. At each terminal stop, a shipment is unloaded from an inbound trailer and reloaded onto an outbound trailer. A load plan determines the specific sequence of terminal transfers to be used for freight moving between each origin and destination. The design of the load plan determines the linehaul transportation and handling costs required to serve customers. We develop an improved very large-scale neighborhood search heuristic for solving an integer programming model for load plan design. The main contributions of this section include (1) the investigation of the pros and cons of optimizing system-wide into a single destination versus optimizing freight for all destinations in a small region, and (2) a solution approach that can find load plans with costs 6 to 7\% lower than those used in practice, and can find 2.5 to 5\% additional cost savings using the same time budget when compared to an approach optimizing system-wide into a single destination. Chapter 4 addresses a strategic planning problem that extends the load plan design problem to consider terminal roles. We investigate two-stage approaches that first identify the set of transfer terminals and then develop the corresponding load plan. Computational results compare the terminals chosen as transfer facilities from the proposed integer programming based local search method with a traditional hub location formulation and a simple facility location formulation to depict the benefits gained from modeling additional information. The key contributions of this section are (1) the introduction of a new hub location problem variant incorporating freight dispatch timing and trailer transportation cost characteristics found in the LTL trucking industry and (2) a solution approach utilizing IP-based local search that demonstrates the importance of incorporating freight dispatch timing. Finally, Chapter 5 summarizes the main conclusions from this dissertation and discusses directions for further research.

Available in PDF, EPUB and Kindle. Book excerpt: Urban Consolidation Centres (UCCs) are often conceived as an enabler to alleviate negative effects associated with distribution of goods in cities, such as traffic congestion and hazardous emissions. UCCs not only have the potential to reduce these effects but also provide alternative distribution solutions by introducing new transhipment points. Despite their potential, UCCs often fail to be self-supporting and are often dependent on subsides, which is not considered to be sustainable in the long run. In response, this thesis takes its point of departure in the two business models elements value propositions and target customers. A business model is often viewed as an enabler to generate revenue and UCCs have the potential to generate revenue by offering services to their customers, and the customers pay for the services. To understand how customers can benefit from UCCs and provide arguments why they should use these, it is important to understand the relationship between customers’ needs and the services UCCs can provide. The purpose of this thesis is to identify and describe the potential relationship between needs of UCC customers and UCC services. The research in the thesis is both explorative and descriptive, where a first step is to identify customer needs, UCC services, and value propositions. The descriptive part is to describe them and it is also the foundation for understanding the relationship between customer needs and UCC services. Through the analysis and discussion, multiple customer needs are identified and described for seven customer groups and the UCC operator; all of which could be considered customers of UCCs. The thesis also adds to the UCC literature with three new identified UCC services: e-commerce with used products, advertisement, and registration in computer system. The outcome of the analysis also provides illustrations of how customer needs can be matched with UCC services. For the most studied customer group, receiver of goods, a total of 29 different matches were identified, which illustrates the possibilities but also the complexity of the relationships. To understand the relationship, three different types of gaps were also identified that have implications for future research. The main contributions to research and the UCC literature in particular are enlargement of the scope of customers and the illustration of the relationships between customer needs and UCC services. The illustrations include contributions such as identifying, mapping and describing the customer needs, UCC services, and value propositions. An important first step is to understand how customer needs and UCC services can be linked, and this thesis provides examples of how this can be achieved. Viewing every stakeholder as a potential customer opens up the opportunity to fulfil their needs and the potential to generate revenue, which in turn could close the gap in the problem of non-self-supporting UCCs. Furthermore, with self-supporting UCCs, the number of freight vehicles can be reduced and this may lead to more attractive cities with less traffic congestion and lower emissions.

Available in PDF, EPUB and Kindle. Book excerpt: In February 2002, the Industrial and Systems Engineering (ISE) De partment at the University of Florida hosted a National Science Founda tion Workshop on Collaboration and Negotiation in Supply Chain Man agement and E Commerce. This workshop focused on characterizing the challenges facing leading edge firms in supply chain management and electronic commerce, and identifying research opportunities for de veloping new technological and decision support capabilities sought by industry. The audience included practitioners in the areas of supply chain management and E Commerce, as well as academic researchers working in these areas. The workshop provided a unique setting that has facilitated ongoing dialog between academic researchers and industry practitioners. This book codifies many of the important themes and issues around which the workshop discussions centered. The editors of this book, all faculty members in the ISE Department at the University of Florida, also served as the workshop's coordinators. In addition to workshop participants, we also invited contributions from leading academics and practitioners who were not able to attend. As a result, the chapters herein represent a collection of research contributions, monographs, and case studies from a variety of disciplines and viewpoints. On the aca demic side alone, chapter authors include faculty members in supply chain and operations management, marketing, industrial engineering, economics, computer science, civil and environmental engineering, and building construction departments.
