Hazardous materials collection with multiple-product loading

Abstract

We present a new hazardous material (HAZMAT) collection problem in which various industrial HAZMATare transported using a homogeneous capacitated truck fleet. Different materials have different risklevels in terms of the size of exposed population. A truck can simultaneously carry different materials.The size of the population exposed to a loaded truck increases if a higher risk material is added to theload. We minimize the total exposed population and the total transportation cost. We present a casestudy in the City of Santiago in Chile to show practical application of our proposed approach.
