Abstract
Factors including unbalanced user travel demand, vehicle charging status, and high operating cost of enterprises have restricted the development of electric vehicle car-sharing. This paper comprehensively considers the impact of multiple dynamic constraints such as user demand, state of charge of electric vehicles, and operating profit on vehicle relocation. The travel behavior of consumers is studied through Multinomial Logistic Regression method. User demand for electric vehicle car-sharing is forecast through Hidden Markov Model. A new vehicle relocation strategy combining staff relocation and user relocation is formulated. With the goal of maximizing enterprise profit, an electric vehicle car-sharing optimization relocation model in region level is finally established. Taking Anting Town as an example to verify the model, the results show that this new vehicle relocation strategy can effectively reduce the operating cost of enterprises, improve the circulation rate and utilization rate of vehicles, and reduce unnecessary waste of resources.
