The Vehicle Routing Problem with Multiple Trips
Non-asset based third-party logistics providers manage fleets of leased vehicles for their customers. Due to high leasing costs, minimizing the number of vehicles employed in daily operations is of primary concern to such firms. Consequently, routings that involve fewer vehicles and potentially longer travel times are favored over routings that involve additional vehicles. Constructing routes t...
متن کاملMulti-Phase Meta-Heuristic for Multi-Depots Vehicle Routing Problem
In this work, we present a multi-phase hybrid algorithm based on clustering to solve the multi-depots vehicle routing problem (MDVRP). The proposed algorithm initially adopts K-means algorithm to execute the clustering analyses, which take the depots as the centroids of the clusters, for the all customers of MDVRP, then implements the local depth search using the Shuffled Frog Leaping Algorithm...
متن کاملA novel heuristic algorithm for capacitated vehicle routing problem
The vehicle routing problem with the capacity constraints was considered in this paper. It is quite difficult to achieve an optimal solution with traditional optimization methods by reason of the high computational complexity for large-scale problems. Consequently, new heuristic or metaheuristic approaches have been developed to solve this problem. In this paper, we constructed a new heuristic ...
متن کاملA Two-Phase Hybrid Heuristic Method for a Multi-Depot Inventory-Routing Problem
In this study, a two phase hybrid heuristic approach was proposed to solve the multi-depot multi-vehicle inventory routing problem (MDMVIRP). Inventory routing problem (IRP) is one of the major issues in the supply chain networks that arise in the context of vendor managed systems (VMI) The MDMVIRP combines inventory management and routing decision. We are given on input a fleet of homogeneous ...
متن کاملMemetic Algorithm for a Multi-Objective Vehicle Routing Problem with Multiple Trips
This paper considers a variant of the vehicle routing problem where vehicles are allowed to take more than one route during the working day. A restricted fleet size is used in order to serve customers’ demand. Therefore, vehicles could exceed the time horizon. The objective is to optimize both maximum overtime and routing cost. A mathematical model has been proposed for the VRPM. A memetic algo...
