چکیده
This paper studies the integration of vehicle routing problem with cross-docking (VRPCD). The aim is to find a set routes deliver products from suppliers customers through cross-dock facility, such that operational and transportation costs are minimized, without violating capacity time horizon constraints. A two-phase matheuristic based on column generation proposed. first phase focuses generating feasible candidate in both pickup delivery processes by implementing an adaptive large neighborhood search algorithm. destroy repair operators used order explore space. second solving partitioning model determine final solution. proposed tested available benchmark VRPCD instances compared state-of-the-art algorithms. Experimental results show competitiveness as it able improve best known solutions for 80 obtain same remaining 10 instances, average improvement 12.6%. On new larger our maintains its solution quality within acceptable CPU times outperforms pure ALNS We also explicitly analyze performance considering time.

A Memetic Algorithm for the Vehicle Routing Problem with Cross Docking
In this paper we address the VRPCD, in which a set of homogeneous vehicles are used to transport products from the suppliers to customers via a cross-dock. The products can be consolidated at the cross-dock but cannot be stored for very long as the cross-dock does not have long-term inventory-holding capabilities. The objective of the VRPCD is to minimize the total traveled distance while respe...

متن کاملA matheuristic based on large neighborhood search for the vehicle routing problem with cross-docking
The vehicle routing problem with cross-docking (VRPCD) consists in defining a set of routes that satisfy transportation requests between a set of pickup points and a set of delivery points. The vehicles bring goods from pickup locations to a cross-docking platform, where the items may be consolidated for efficient delivery. In this paper we propose a new solution methodology for this problem. I...

متن کاملA Multi-Objective Imperialist Competitive Algorithm for Vehicle Routing Problem in Cross-docking Networks with Time Windows
This study addresses the pickup and delivery problem for cross-docking strategy, in which shipments are allowed to be transferred from suppliers to retailers directly as well as through cross-docks. Usual models that investigate vehicle routing in cross-docking networks force all vehicles to stop at the cross-dock even if a shipment is about to a full truckload or the vehicle collects and deliv...
