Reverse Logistics in Recycling Companies Using a CVRP Approach

At present, the generation of waste has increased, due to the high consumption of products and the lack of an efficient collection system as well as its correct disposal of waste, causing it to end up in clandestine dumps or sanitary landfills without these being able to be reused or recycled. In Mexico there are companies that seek to solve this problem, for which they are destined to the collection and correct disposal of MSW, in order to support the companies that generate products so that they can recover them, and these can be reused and used giving them a new use. In order for a greater number of companies to implement a collection process, what is needed is to apply a model where companies have the capacity to cover the generated demand, covering the collection points with a route that minimizes the cost of the process. For this reason, the proposal of this research is to improve a reverse logistics network in its collection process, where the demand points where the MSW are collected are located, the distances between each of the points, logistics costs, using the vehicles destined for collection taking into consideration their capacity. For this reason, it is proposed to apply a model of routing problem with limited CVRP capacity, where routes are generated that cover all collection points, minimize the cost of operation, and take into account the capacity of the vehicles that the company has. The solution must determine the number of vehicles necessary for the process, as well as the order in which each vehicle must visit the generating points, and thus increase the collection of waste, meeting the growing demand.
