【Abstract】 To solve the vehicle routing problem with time windows and multiple deliverymen, we adopt a hybrid heuristic algorithm, which is characterized by the hybridization of the integer programming recombination, the local search(LS) algorithm and the simulated annealing(SA) algorithm. In the proposed algorithm, the integer programming recombination is capable of providing better solutions for further improvement, and LS and SA make a good balance between exploration and exploitation. Computational results indicate the proposed algorithm is more effective than CPLEX and the tabu search algorithm.更多还原
