Value-at-Risk model for hazardous material transportation

This paper introduces a Value-at-Risk (VaR) model to generate route choices for a hazmat shipment based on a specified risk confidence level. The objective is to determine a route which minimizes the likelihood that the risk will be greater than a set threshold. Several properties of the VaR model are established. An exact solution procedure is proposed and tested to solve the single-trip probl...

Aiding Route Decision for Hazardous Material Transportation

This research attempts to build a framework for determination of optimal routes for hazardous material transportation. Previous works have suggested incorporation of many conflicting objectives in the analysis, such as travel cost, population exposure, environmental risk or security concerns. Multiplying the number of objectives leads to complex shortest path problems that often have several ef...

Application of Chaos Theory in Hazardous Material Transportation

Risk factors are generally defined and assigned to road networks, as constant measures in hazmat routing problems. In fact, they may be dynamic variables depending on traffic volume, weather and road condition, and drivers' behavior. In this research work, risk factors are defined as dynamic variables using the concept of chaos theory. The largest Lyapunov exponent is utilized to determine the ...

Generalized route planning model for hazardous material transportation with VaR and equity considerations

Recently, the Value-at-Risk (VaR) framework was introduced for the routing problem of a single hazmat trip. In this paper, we extend the VaR framework in two important ways. First, we show how to apply the VaR concept to a more realistic multi-trip multi-hazmat type framework, which determines routes that minimize the global VaR value while satisfying equity constraints. Second, we show how to ...

Optimization of Vehicle Routing and Scheduling Problem with Time Window Constraints in Hazardous Material Transportation

Unlike widely available literatures in hazardous material (HAZMAT) transportation that basically aim at finding non dominated paths for a given origin-destination pair, our main focus in this study is on vehicle routing problem with time window (VRPTW) aspect of HAZMAT transportation problem that has received very less attention in literatures. We present a new multi-objective optimization mode...
