Construction industry around the world is well-known as a massive contributor of waste materials and environmental impacts. Among types generated by this are concrete, plastic, wood, ceramic, asbestos. These materials, in general, chemically fused through various manufacturing processes before being transported for construction usage. Addition chemical compounds such arsenic, copper, cyanide, n...

This paper considers a multi-depot heterogeneous vehicle routing problem (MDHVRP) with time windows, which is very crucial for hazardous materials transportation. For this reason, we formalize as multi-objective MDHVRP optimization model, where the actual load dependent risk of transportation considered. To solve problem, propose hybrid evolutionary algorithm (HMOEA) and two-stage (TSA). In add...
