One of these problems that have appeared during the last few years is the Double Traveling Salesman Problem with. Multiple Stacks (DTSPMS), a vehicle routing problem in which some pickups and deliveries must be performed in two independent networks, verifying some precedence and loading constraints imposed on the vehicle. In this paper, four new neighborhood structures for the DTSPMS based on reinsertion and permutation of orders to modify both the routes and the loading planning of the solutions are introduced and described in detail. They can be used in combination with any metaheuristic using local search as a subprocedure, guiding the search to unexplored zones of the solution space. Some computational results obtained using all proposed neighborhood structures are presented, providing good quality solutions for real sized instances.engjournal articlehttps//doi.org/10.1007/s11750-009-0080-9http://www.springerlink.com/content/n165424710362747/fulltext.pdfrestricted access517.986Traveling Salesman ProblemMetaheuristicsNeighborhood StructuresPrecedence ConstraintsLifo LoadingEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
