摘要
带时间窗的车辆路径问题(VRPTW)是交通运输行业中一个非常重要的问题,因为它在日常实践中经常发生,例如安排银行交货。针对这个np困难问题,已经提出了许多启发式算法。本文报道了基于有向无环图模型的进化算法GrEVeRT (graph -based evolution algorithm for the Vehicle Routing Problem with Time window)的成功应用。在已知的VRPTW基准实例上,我们获得了比其他研究人员使用遗传算法报道的更好的结果。
Evolving schedule graphs for the vehicle routing problem with time windows
The vehicle routing problem with time windows (VRPTW) is a very important problem in the transportation industry since it occurs frequently in everyday practice, e.g. in scheduling bank deliveries. Many heuristic algorithms have been proposed for this NP-hard problem. This paper reports the successful application of GrEVeRT (Graph-based Evolutionary algorithm for the Vehicle Routing Problem with Time windows), an evolutionary algorithm based on a directed acyclic graph model. On well-known benchmark instances of the VRPTW, we obtain better results than those reported by other researchers using genetic algorithms.
