Solid waste management: case of collection and Vehicle Routing Problem in the city of Azemmour, Morocco

AbstractThis paper considers a truck scheduling problem in the context of solid waste collection in the City of Azemmour. One such concern to city administrators is how to effectively distribute collection vehicles and crews in the region. The main object of this paper is to suggest a methodology for allocating trucks to the existing collection sites for minimizing cost and collecting 100% of waste. For this purpose, the software “Container Collector” was developed. This last is equipped with a file containing the application data that are required to represent the road network, the container position and the collection depot spatial information. In fact, the software allows determining routes which must be traversed in the city to optimize the vehicle routing. Thus, the software application has permit to determine four optimal routes which allow minimizing total distance traversed, total rounds duration and financial costs including salary, fuel and vehicle operation.
