Abstract: The distribution plan of electric bicycle-sharing batteries has a great impact on the users' immediate experience and the interests of the company. In order to develop an optimal distribution scheme and truly get through "the last mile" of people's travel, the requirements of enterprises for the distribution cost and the users' requirements for timeliness are considered, and a model of vehicle routing problem with soft time windows with objectives of minimizing the total distribution cost and maximizing user satisfaction is established. Then the traditional genetic algorithm is improved by sweep algorithm and the crossover operator based on the cost of optimal path. Finally, an example is adopted to verify that this model and the improved algorithm are effective. And the correlation between population size, iteration number and optimal solution is found by numerical experiments.

Key words: distribution problem of electric bicycle-sharing batteries, vehicle routing problem with soft time windows, sweep algorithm, genetic algorithm
