This paper addresses the disruption problem caused by the request changes of customers in a predetermined vehicle distribution plan. In this paper, vehicle routing problem with simultaneously pickup and delivery (VRPSPD) is considered. Based on the idea of disruption management, the impacts of disruption issues on both cost and service time were analyzed. A disruption management model was established...
We herein present a tabu search algorithm with variable cluster grouping (TSVCG for short) to deal with Multi-depot vehicle routing problem (MDVRP for short). In TSVCG, we firstly adopt variable cluster grouping to convert a complicated MDVRP to typical single depot vehicle routing problem (SDVRP for short). And then we apply a tabu search algorithm to solve each SDVRP. In the grouping process, we...
