This paper focuses on Intermodal Freight Transportation broadly defined as a chain made up of several transportation modes that are more or less coordinated and interact in intermodal terminals to ensure door-to-door service. The goal of the chapter is to present intermodal transportation from both the supplier and the carrier perspectives, and identify important issues and challenges in design...
This Chapter focuses on Intermodal Freight Transportation, broadly defined as the transportation of a load from its origin to its destination by a sequence of at least two transportation modes, the transfer from one mode to the next being performed at an intermodal terminal. Container-based transportation services are an important part of intermodal transportation and the backbone of internatio...
Intermodal freight transport has received an increased attention due to problems of road congestion, environmental concerns and traffic safety. A growing recognition of the strategic importance of speed and agility in the supply chain is forcing firms to reconsider traditional logistic services. As a consequence, research interest in intermodal freight transportation problems is growing. This p...
This work investigates an intermodal transportation system for delivering goods from a Regional Distribution Centre to supermarkets on the Isle of Wight (IOW) via the port of Southampton or Portsmouth in the UK. We consider this integrated logistics chain as a 3-echelon transportation system. In such a system, there are two types of transport methods used to deliver goods across the Solent Chan...
Managing logistics processes from an environmental perspective is increasingly important in international supply chains. Essential elements of global are chains based on intermodal logistic units. The specificity this type shipment, which often involves several modes transport, requires a precise definition model boundaries and identification specific factors determining the level carbon footpr...
Given a set of players and the cost of each possible coalition, the question we address is which coalitions should be formed. We formulate mixed integer linear programming models for this problem, considering core stability and strong equilibrium. The objective function looks for minimizing the total cost allocated among the players. Concerned about the difficulties of managing large coalitions...
The transport system is one of the main bottlenecks world’s largest producer and exporter soybeans, Brazil. Long-distance truck transportation grains increases costs, food waste, CO2 emissions. To handle these problems, Brazilian government seeks to expand through national logistics plan (PNLT), promoting efficient operations. Collaborating on environmental aspect, this paper proposes sustainab...
We propose efficient intermodal transportation auctions for the B2B e-commerce logistics problem (ELP). This paper is among the first to consider transaction costs into auctions. In the ELP, the shipper is a B2B e-commerce platform by which a number of online orders between goods sellers and buyers are generated, and 3PLs (third-party logistics providers) can fulfill these online orders. The sh...
This is a case study of a coal mining company to demonstrate how algebra principles and nonlinear goal programming can be applied for logistics planning using spreadsheet software. The paper asserts that mathematical programming techniques are not well-accepted by managers because the models are difficult to understand due to abstract notational conventions yet alternative commercial software i...
| In this paper we apply the concepts of Vector Quantization (VQ) for the determination of arbitrary distance functions { a problem which has important applications in Logistics and Location Analysis. The input to our problem is the set of coordinates of a large number of nodes whose inter-node arbitrary \distances" have to be estimated. To render the problem interesting, non-trivial and realis...
