In this paper we introduce an extension of the vehicle routing problem with time windows (VRPTW) called the Load-dependent Capacitated Vehicle Routing Problem with Time Windows (LDVRPTW). This problem differs from the classical VRP and VRPTW on the transportation costs, which are calculated not only on the travel distance, but also the loads on the arcs. We propose a metaheuristic to address this...
Nowadays in the transportation industry carriers reduce the costs through collaboration, e.g., sharing the assets and tasks with other collaborative partners. In this paper, an optimization problem called the Close-Open Mixed Vehicle Routing Problem (COMVRP) is discussed, that can be used to assist in identifying routes when a carrier serves the customers through his private vehicles and vehicles...
The open capacitated arc routing problem (OCARP) is defined and considered in this paper. The OCARP differs from the classic capacitated arc routing problem (CARP) because the vehicles are not required to return to the depot. The OCARP seeks to find a set of minimum cost open routes that serve task arcs of a given graph, subject to vehicle capacity and travel distance span restrictions. A mathematical...
