【摘要】 近年来,客户对货物运输的时效性要求越来越高,而城市交通拥挤和延误不仅会延误送货时间,而且会增加运输企业的运输成本,解决此问题的关键在于能够充分考虑交通动态信息,因此,建立基于动态交通信息的带时间窗约束的最优路径选择模型成为目前业界研究的热点问题。本文作者建立了基于动态交通信息的带时间窗约束的最优路径选择模型,并利用TransCAD仿真软件对模型进行了实现。结果不仅表明模型的有效性,而且提供了一种动态路径选择模型快速可视化实现的有效方法。更多还原

【Abstract】 Recently, customer have more strict request of timeliness to freight than the past, But the increasing traffic congestion and the queuing delay time not only delay the time of freight ,but also become the mostly reason that bring great loss on property for transportation enterprises, the key to resolve the problem is to sufficiently consider the dynamic traffic information. So there are the hot issues to establish the model of the vehicle routing problem with time windows( VRPTW)based on dynamic traffic information. The authors has built the optimum routing model of VRPTW, We simulate the model by software of TransCAD , The result of simulate show that the mode is effective ,What’s more, the paper put forward an effective way that can quickly achieve the simulation of optimum routing mode.更多还原
