| Descripció: | In this work, we present two matheuristic techniques based on two heuristic techniques: Ant system (AS), method of musical composition (MMC) and two exact methods: Primal-dual algorithm (PDA) and dual simplex algorithm (DSA). These techniques are denoted as DS-AS-PDA and DS-MMC-AS and are characterized by taking advantage of the information of the structure and characteristics of the mathematical model for the vehicle routing problem with time windows (VRP-TW). In order to characterize the behavior of the techniques proposed in this work, we use 29 test instances for the VRP-TW. The numerical results show that DS-AS-PDA and DS-MMC-AS exhibit robust behavior and are capable of generating the best solutions reported in the literature with a smaller number of calls to the objective function. |
