Abstract: The layout of renting network is the fundamentals of the car sharing business. To provide a framework for assisting the layout of electric vehicles(EVs)sharing network, this paper analyzes the basic characteristics of the development of the EVs sharing network and constructs the corresponding optimal layout algorithm. Firstly, the profit feature of one single EVs sharing commercial lot is analyzed, which takes into account the network effects; and then the profit feature of the whole commercial network is inferred. The main conclusions are as follows: the positive and negative network effects could influence the profit characteristic of every EVs sharing lot; the layout order would affect the profit of the whole EVs sharing network; based on the above conducting outcomes, the Two Step Clustering Firefly Algorithm is put forward, which could not only improve the search precision and efficiency through the classification of the candidate lots, but also could give the layout order of EVs sharing lots. Finally, the applicability of the proposed algorithm is further demonstrated by an example analysis.
