Cross docking is a logistics strategy that strives to reduce inventory holding costs, shipping costs, and delays in delivering the products. In this research, an optimization model is presented for split loading and unloading products by suppliers and customers, vehicle routing with fuzzy possibilistic time window constraints among them, assignment of vehicles to cross dock, consolidation and i...

Neighborhood search is a cornerstone of state-of-the-art traveling salesman and vehicle routing metaheuristics. Whereas neighborhood exploration procedures are well-developed for problems with individual services, their counterparts one-to-one pickup-and-delivery more scarcely studied. A direct extension classic neighborhoods often inefficient or complex because the necessity jointly considerin...

One important requirement of modern supply chain management is the frequent exchange containers via multiple cross-docks which requires spatial and time synchronisations between different types vehicle. Moreover, as collaborations in logistics several companies become popular, more flexible extended models must be solved to consider needs companies. This high importance a new concept, Physical ...

This paper presents a meta-heuristic, which is based on the Threshold Accepting combined with modified Nearest Neighbor and Exchange procedures, to solve the Vehicle Routing Problem with Backhauls and Time Windows (VRPBTW). The VRPBTW assumes that trucks initially start from the depot, deliver goods to the linehaul customers, successively pickup goods from the backhaul consumers, and finally re...
