Description
Summary:One of the main characteristics of real transportation problems is not only the complexity of designing their models but also the characterization of the elements that make up the supply chain. A more detailed study will certainly provide more information about the system. However, the use of regular networks for the development of models can remove key characteristics needed for correct decision making, so we propose the characterization of transport models through the conceptualization of complex networks. The methodology proposes a mechanism for the reconstruction of the network when the distribution network is under attack, and any of its nodes or arcs stop operating; making it very hard to find a solution to the vehicle routing problem. In this way by reconstructing the route and the cost matrix it is possible to obtain feasible routes. The purpose of this research is to show how the proposed methodology can be applied.
