Abstract

The shipment of hazardous materials is challenging due to the risk that the population centers face during transportation. The policy makers often have concerns for ensuring a balanced allocation of the risks to the population centers. We structure this problem as an equitable optimization problem with multiple objectives aiming to minimize the risk exposure of different neighborhoods. The resulting multiobjective mixed integer linear programming problem is solved to provide the policy makers equitably nondominated options, each with different levels of efficiency (total risk) and fairness (allocation of risk).
