Application of a heuristic method and mathematical modeling for the design of vehicle routes in the company Eco Urban S.A of the city of Toluca State of Mexico
The Vehicle Routing Problem, VRP (Vehicle Routing Problem) proposes solution alternatives for Eco Urban SA, a Mexican company in charge of collecting post-consumer PET (Polyethylene Terephthalate) material at different dispersed collection points in the city of Toluca, State of Mexico. , taking into account that the company does not have a VRP study that allows it to efficiently choose the path to follow to collect the material. For this reason, the design of a vehicle route for the collection of PET was proposed, which minimizes the transportation costs associated with the operation carried out by the company. To do this, identifying relevant aspects such as capacity, travel distances from the storage warehouse to the collection points characterized the current collection system. Then, the mathematical model is formulated defining indices, variables, parameters and constraints that limit the objective function to obtain the optimal route. The heuristic sweep method is defined and developed. Finally, the results of the study models and the current collection system are analyzed and compared, exposing the best vehicular route for the collection of PET that operates at minimum cost.
