MATHEMATICAL MODEL FOR RESEARCH OF INTERNATIONAL RAILROAD GOODS TRANSPORTATION

A Tactical Planning Model for Railroad Transportation of Dangerous Goods

Railroad transportation of hazardous materials did not receive as much attention as highway transportation in the academic literature, although comparable volumes are shipped via these two transport modes in North America and Europe. In this paper we present an optimization methodology for the railroad tactical planning problem with risk and cost objectives. We determine the routes to be utiliz...

Railroad transportation of dangerous goods: Population exposure to airborne toxins

Hazardous materials are potentially harmful to people and environment due to their toxic ingredients. Although a significant portion of dangerous goods transportation is via railroads, prevailing studies on dangerous goods transport focus on highway shipments. We present an analytical framework that incorporates the differentiating features of trains, notably volume and nature of cargo, in the ...

A Fuzzy Bi-Objective Mathematical Model for Sustainable Hazmat Transportation

Today, transportation of hazardous materials (i.e., hazmat) is a very important issue for researchers due to the risk of this transit, which should be considered for development of industries and transportation. Therefore, a model that is useful should consider the risk and damage to humanitarian and environmental issues due to transit of hazmat materials. By considering the related cost, the r...

Optimizing Railroad Tank Car Safety Design to Reduce Dangerous Goods Transportation Risk

This paper describes an optimization model developed to determine the most efficient way to enhance the safety design of tank cars used to transport toxic inhalation hazard (TIH) materials in North America and a quantitative risk analysis conducted to assess the risk and potential benefit of implementing enhanced safety-design tank cars. The conditional probability of release and the car's weig...
