Abstract: MultiDepot Open Vehicle Routing Problem with soft time windows is a variation of the Vehicle Routing Problem constrained by multidepot and soft time windows,which is a typical NP-hard problem.The mathematical model and example about the problem are built,an improved Tabu Search(TS) is designed to solve the problem.Excellent computational results of examples obtained quickly show the right of the model and goodness of the algorithm.
