报告题目:A fuzzy dual toll policy for regulating the transportation of hazardous materials

内容简介:A dual-toll policy, considering a multi-degree fuzzy incident rate, is proposed to mitigate the risk caused by hazardous materials (hazmat) transportation in a road network. To address several carriers transporting multiple types of hazmat, we use a bi-level programming formulation. The upper and lower levels reflect the decision problems for the regulators (regional and local governments), and for travelers (hazmat and non-hazmat), respectively. The "risk equity" (minimization of the maximum link risk) is addressed in addition to the total network risk, so that the spatial distribution of risk is closer to homogeneous. Hazmat and non-hazmat travelers make routing decisions by arranging their transportation flows in light of the corresponding tolls posed by the regulators. To solve the model effectively, a genetic-algorithm-based methodology is employed along with a piecewise linearization method and a Frank-Wolfe approach. Employing the Sioux Falls network, we present case studies which illustrate managerial insights from the dual toll policy and various degrees of incident possibilities, when differing hazmat tolls are imposed on distinct types of hazmat shipped by multiple carriers.
