The paper is concerned with a hazmat vehicle routing problem. Two objectives are considered: (1) minimizing the total travel cost and (2) minimizing the total travel risk. A path-based risk estimation method is proposed to make the risk analysis more reasonable. A numerical study is carried out and the non-dominated solution is calculated by the modified ant colony optimization. Results show that...
Hazardous materials (hazmat) transportation vehicles can be viewed as potential targets for terrorist attack because of the serious health and environmental risk produced by hazmat release. Some effective approaches in attack and disaster preparation are to restrict the transportation of hazmat on some high risk links, design robust routing schemes that direct hazmat vehicles through minimal risk...
