A Rectangular Multiregional Model for Freight Transportation Forecasting

Multiregional SIR Model with Infection during Transportation

We present a general epidemic model to describe the spread of an infectious disease in several regions connected by transportation. We take into account that infected individuals not only carry the disease to a new place while traveling from one region to another, but transmit the disease during travel as well. We obtain that a model structured by travel time is equivalent to a large system of ...

Multimodal Statewide Freight Transportation Model

A mathematical model for hazmat and freight transportation in railway networks

In this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. In the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. It is assumed that the sequence of the trains in the network is known. The objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

A game theoretic ”mode-choice” model for freight transportation∗

This paper uses simple game theory to analyze a situation where two agents compete in the transport market. The modeling frame is that of a mode choice model, where the two mode options are boat or car transportation. The basic findings are that non pareto optimal (car, car) equilibrium outcomes, may occur in a surprisingly large amount of cases. Additionally, the possible different Nash equili...

Dynamic Models for Freight Transportation

Freight transportation is characterized by a variety of dynamic information processes: the demands of customers, the performance of people and equipment, and the performance of the network. In addition, large networks are characterized by how they organize decisions and information: who makes what decision with what information? This chapter approaches the development of models for freight tran...
