Abstract: The characteristics of online resources make it necessary to serve customers by using the lease mode of sharing distribution vehicles, but the resultant distribution routing becomes challenging due to multiple fuzzy time windows. In this paper, a VRP model of simultaneous pickup and delivery goods in multiple centers with fuzzy time window is constructed to minimize the distribution cost and the number of vehicles used, and maximize the service quality. By taking the service time window expected by customers, hard time window and soft time window into consideration, this model improves the linear trapezoid membership function to express customer fuzzy satisfaction, and uses the adaptive large-scale neighborhood search algorithm for solution, with a variety of group search mechanisms and nondominated sorting operations introduced to speed up the algorithm convergence and enhance the global optimization ability of algorithm. Finally, the validity and the superiority of the model and the improved algorithm are verified by solving a numerical example.
