Abstract: Public bicycle sharing systems aim at solving the last mile problem of residents, and offer a low cost and environmentally friendly mean of transportation for short travels. However the systems involve many factors including population flow, the traveling approach and traffic condition, they are hard to be described by mathematical models quantitatively. In this paper, the operation processes of the public bicycle system are modelled in Plant Simulation based on the system modeling methodology. The service level and the utilization ratio of the facilities are used as the index, and the deployment of the servicing stations are analyzed. To further balance the servicing quality and the utilization rate of bikes, the sensitive analysis is integrated to the iteration optimization process. The more reasonable deployment number of assigned bicycle of the stations is obtained. The simulation results show the optimized number of assigned bicycles of the servicing stations can improve the servicing performance of the public bicycle systems.
