Ruin and Recreate Approach Applied to Multi-objective Optimization of HHC VRPTW in the Case of Medical Waste Collection

Abstract

The management of medical waste in Morocco has always been the concern of the health department. Recently the World Health Organization, who classified the medical waste in Morocco as a time bomb, recommended involving of professionals interested in that management. Through this paper we proposed a model of collectors' management, on behalf of clinics in case of Casablanca region. This model, as part of a heterogeneous fleet vehicle routing problem, aims at multi-objective optimization between the pillars of sustainable development. The complexity of the model is managed using a Ruin and Recreate heuristic. Finally, the tuning of weighting parameters is being experimented to show how it will be possible to find a compromise between conflicting objectives in the case of medical waste logistics'.
