Shipping hazardous material (hazmat) places the public at risk. People who live or work near roads commonly traveled by hazmat trucks endure the greatest risk. Careful selection of roads used for a hazmat shipment can reduce the population at risk. On the other hand, a least time route will often consist of urban interstate, thus placing many people in harms way. Route selection is therefore th...

This paper focuses on the effects of weather systems on hazmat routing. We start by analyzing the effects of a weather system on a vehicle traversing a single link. This helps characterize the time-dependent attributes of a link due to movement of the weather systems. This analysis is used as a building block for the problem of finding a least risk path for hazmat transportation on a network ex...

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...

in the case of hazardous materials management, selected routes for carrying hazardous materials (i.e.,hazmat) have significant effects on locating hazmat distribution centers. since, risk and cost are usuallyconsidered as two main attributes to determine the best routes, optimized locations are sequentially outlineddepending on selected routes. in the present paper, two different approaches of ...

today, transportation of hazardous materials (i.e., hazmat) is a very important issue for researchersdue 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 humanitarianand environmental issues due to transit of hazmat materials. by considering the related cost, thereali...

Hazardous material (Hazmat) transportation is an inseparable section of the industry, despite its major financial and health risks. In order to optimize Hazmat transportation, a multi-objective routing model with time windows employed where risk distance are minimized. Due uncertainty risk, Z-number fuzzy approach used estimate in which probability occurrence severity considered context Z-infor...

This paper provides a comprehensive review in the domain of hazardous material transportation from an Operational Research point view. The paper's focus lies on hazmat routing, routing-scheduling, and network design problems. objective this is twofold: (1) reviewing models’ assumptions, objectives constraints, decisions, input parameters, basic modeling/solution techniques, case studies, (2) hi...

Due to catastrophic consequences of accidents by hazardous materials (hazmat) transportation, a risk-averse approach for routing is appropriate for risk mitigation. In this paper, we consider spectral risk measures, which are coherent and more general than existing approaches such as conditional value-at-risk. In spectral risk measures, one can define the spectrum function precisely to reflect ...

The railroad industry is being challenged by recent state regulations requiring the disclosure of routing information of trains carrying hazardous materials (hazmat) to the general public. While there is a need to know, the dissemination of such information is contrary to both industry practice and Federal Railroad Administration (FRA) rules. The conundrum is that there needs to be disclosure t...
