In this paper, a mathematical model of logistic vehicle routing problem with time windows(LVRPTM)is given, and an improved genetic algorithm is proposed based on the novel crossover operator. When this algorithm is used for solving LVRPTM, it can obtain general optimality of all evaluate index on the premise of satisfying every customer's demand. This algorithm has more superior performance than PMX and RC, and it is a preferable scheme for LVRPTM, which is proved by a number of experiments.
