An improved service of carsharing, one-way service enables customers to use the vehicles from one station and return to other station. The common issue in one-way carsharing service is that the vehicle stock of each station become imbalance, thus will lead to the less customer satisfaction and less utilization of vehicles. Consequently, the relocation is used by the system to move the appropriate vehicle to a high demand station in order to elevate customer satisfaction. This paper will demonstrate the periodically relocation model for a one-way carsharing system and tested on simulation model. Computational simulation result on commercially operational data of carsharing in South Korea is involved to solve the relocation problem in one-way system. The results we have obtained in this study provide a clear insight into the impact of model on low relocation cost compared to the traditional relocation.
