Author: Dr. Jean-Paul Rodrigue Bottlenecks impose delays and restrictions in the normal flow of transportation and can be related to infrastructure, regulations or operations. 1. Transport Bottlenecks The formation of bottlenecks is the outcome of three factors that can be individual or concomitant, for complex bottlenecks: The effects of bottlenecks

Author: Dr. Jean-Paul Rodrigue Petroleum remains a strategic resource in the global economy, underlining the challenges of producing and transporting oil. [TO BE UPDATED] 1. Petroleum Very few commodities have become as vital as petroleum since it can be used as a source of energy and a raw material in

Authors: Dr. Shih-Lung Shaw and Dr. Jean-Paul Rodrigue Geographic Information Systems for Transportation (GIS-T) refer to the principles and applications of geographic information technologies to transportation problems. 1. GIS in Transportation In a broad sense, a geographic information system (GIS) is an information system specializing in the input, management, analysis,

Globalization and more reliable cold chains can have significant impacts on commodity chains, by expanding available options for each sequence of the supply chain. This results in an increase in the quantity and quality of products available on markets as well as lower costs. The example depicted on the figure

Three operational conditions (processes) are fundamental in a cold chain:

A cold chain can functionally be considered as the close interaction between three technologies: Operational conditions within the cold chain must be consistent so that the processes of load and transport integrity of the shipments are maintained.

Authors: Dr. Jean-Paul Rodrigue and Dr. Theo Notteboom The cold chain involves the transportation of temperature-sensitive products along a supply chain through thermal and refrigerated packaging methods and the logistical planning to protect the integrity of these shipments. 1. The Cold Chain While globalization has made the relative distance between

Author: Dr. Jean-Paul Rodrigue In addition to providing a conceptual background to the analysis of the mobility of passengers and freight, transport geography is an applied science relying on quantitative and qualitative methods. 1. Transportation and Methodologies Transportation is not a science but a field of inquiry and application. Two

One dimension of green logistics concerns food supply chains and the growing awareness that supplying food products to consumers concerns large distances.

While costs have always been an essential driver of supply chain management strategies, the negative energy and environmental footprint of many supply chains has been a strong incentive to improve what is known as green supply chain management. Since logistics are related to all the activities involved in making goods
