Abstract: The present disclosure provides a bike sharing rebalancing optimization method based on an adaptive neighborhood search algorithm. First, based on a difference between locations of shared bikes and users' travel demands in temporal and spatial distribution, a bike sharing rebalancing model is constructed. Next, an adaptive neighborhood search algorithm is constructed by using an adaptive operator selection mechanism and based on the fusion of a large neighborhood search algorithm and a neighborhood search algorithm. Then, seven types of perturbation operators, six types of repair operators, and eight types of neighborhood search operators are designed based on features of rebalancing time, pickup-and-delivery actions, and a capacity limit of a vehicle. Finally, a termination condition is constructed such that the algorithm terminates at an appropriate time and an optimization solution for a rebalancing route is provided.
