论文摘要
本文考虑了一个无人的车辆机器人皮卡和交付系统,其中一辆以母船从仓库到附近分发的许多站点的自动驾驶车辆,以多个无人驾驶机器人的形式运送多个货车,以执行多个接送服务和送货服务。首先,我们将其作为一个具有时间限制的多模式车辆路线问题(MMVRP),这是杂货店和实际上食品交付的典型服务要求。然后,我们将其作为混合整数四二次结合程序(MIQCP)模型来确定最佳集成路由计划(车辆路由和机器人路由),以最大程度地减少所有服务的总加权拖延。最后,使用Python中的Gurobi求解器解决了小型和中等大小的问题实例,以证明所提出的MIQCP模型的有效性和性能。
This paper considers an unmanned vehicle-robot pickup and delivery system, in which a self-driving vehicle carrying multiple unmanned robots in the form of the mother ship travels from a depot to a number of stations distributed in a neighborhood to perform multiple pickup and delivery services. First of all, we present it as a Multi-modal Vehicle Routing Problem (MMVRP) with time constraints, which are typical service requirements for grocery and food delivery in practice. We then formulate it as a Mixed Integer Quadratically Con-strained Program (MIQCP) model to determine the optimal integrated routing plan (vehicle routing and robot routing) to minimize the total weighted tardiness of all services. Finally, a small-size and a medium-size problem instance are solved using the Gurobi solver in Python to demonstrate the validity and the performance of the proposed MIQCP model.
