Vehicle Routing Problem and Hazmat Transportation
Providing safe transportation for Hazardous Materials (Hazmat) is a concern that attracts a wide range of resaerchers. Different types of problems have been defined in the literature in order to cope as much as possible with real situations. Most of existing studies consider the transportation between two points, while few of them considered resolving the Vehicle Routing Problem (VRP) in the co...
متن کاملRouting Hazardous Materials on Time-Dependent Networks using Conditional Value-at-Risk
We propose a new method for mitigating risk in routing hazardous materials (hazmat), based on the conditional value-at-risk (CVaR) measure on time-dependent vehicular networks. The CVaR models are shown to be flexible and suitable for hazmat transportation that can be solved efficiently. This paper extends the previous research by considering CVaR for hazmat transportation in the case where acc...
متن کاملWorst-Case Conditional Value-at-Risk Minimization for Hazardous Materials Transportation
Despite significant advances in risk management, routing hazardous materials (hazmat) has relied on relatively simpler methods. In this paper, we formally introduce an advanced risk measure, called conditional valueat-risk (CVaR), applied to truck routing problems for hazmat transportation. We find that CVaR offers a flexible, risk-averse, and computationally tractable routing method that is ad...
متن کاملHeuristic Multiobjective Search for Hazmat Transportation Problems
This paper describes the application of multiobjective heuristic search algorithms to the problem of hazardous material (hazmat) transportation. The selection of optimal routes inherently involves the consideration of multiple conflicting objectives. These include the minimization of risk (e.g. the exposure of the population to hazardous substances in case of accident), transportation cost, tim...
متن کاملMultimodal Transportation p-hub Location Routing Problem with Simultaneous Pick-ups and Deliveries
Centralizing and using proper transportation facilities cut down costs and traffic. Hub facilities concentrate on flows to cause economic advantage of scale and multimodal transportation helps use the advantage of another transporter. A distinctive feature of this paper is proposing a new mathematical formulation for a three-stage p-hub location routing problem with simultaneous pick-ups and de...
