OPTIMIZING CONTAINER LOCATION FOR SELECTIVE COLLECTION OF URBAN SOLID WASTE

Municipal solid waste management includes several functional phases such as waste generation, storage, collection, transportation, processing, recycling and disposal in a suitable landfill. Waste collection and transportation phases are closely related, since the deployment of containers along the city determine the vehicle fleet size required for picking up the collected waste into the containers and the design of efficient routes needed for that purpose. A mathematical model for the deployment of containers in a context of selective collection of urban solid waste, has been formulated in this work. A greedy algorithm of overflowing deviated to the immediate neighbourhood has also been developed to solve the proposed mathematical programming model. In order to evaluate the performance of the developed methodology, a computational experience has been carried out on an urban system inspired in a zone belonging to the area of Seville, Spain.
