Title: MINIMAX POPULATION EXPOSURE IN ROUTING HIGHWAY SHIPMENTS OF HAZARDOUS MATERIALS
Accession Number: 00743673
Record Type: Component
Record URL: Availability: Find a library where document is available Abstract: A routing model for hazardous materials with two objectives--to minimize maximum population exposure and to minimize total travel time--is introduced. The population exposure is quantified by the number of people in an impact circle of a selected radius. To solve this two-objective problem, the focus is placed on the second objective, with a constraint on the first objective. This results in a problem that is easy to solve and has a solution that is easy to interpret. To demonstrate the use of this model, a case of nuclear waste shipments (i.e., spent fuel) in the United States in considered. The model is applied, with two bounds on high-level population exposure, to 10 nuclear waste origins. The results of this application are reported. The model behaves in a predictable (and desirable) way, avoiding major population centers via detours. With its ability to quantify tradeoffs between competing objectives, and its capacity to generate multiple routes for a shipment, the model has the potential to serve in a decision-support role for planning hazardous materials routes.
