摘要
考虑了带可选时间窗约束的车辆调度问题(简称VRPATW),对现有的单时间窗约束的车辆调度模型进行了拓展,建立了VRPATW的数学模型,并进一步构造改进的禁忌搜索算法用于问题求解,算法首先用改进的PFIH算法提供较好的初始解,然后利用禁忌搜索对初始解进行改进,最后通过实验结果,说明该算法能够有效的解决100个用户的VRPATW问题。
The Vehicle Routing Problem with Alternative Time Windows (VRPATW) was studied. Based on the model of VRP with single time window constraint, a model of VRPATW was built, and an improved Tabu Search algorithm was introduced. The algorithm first generates a good feasible initial solution, using improved PFIH algorithm, then improves the initial solution using Tabu Search. Finally the experiment results show that the algorithm can solve 100 customers VRPATW efficiently.
