Benefit distribution in shared private charging pile projects based on modified Shapley value

Private charging pile sharing is an innovative business model alleviating the shortage of well-developed publicly accessible charging infrastructure, which has been evident in large cities. However, the lack of effective benefit distribution scheme impedes the implementation and promotion of private charging pile sharing projects. To address this deficiency, an improved Shapley value model is developed. First, risk, input and service quality are identified as the key factors to improve the deficiencies in the allocation of benefits based on the contribution. Second, the modified Shapley value method is established based on the cloud gravity center, which to determine the correction value of each distribution factor. This is combined with the modified Shapley value to ensure fair distribution of benefits arising from the private charging pile sharing. An example is given to illustrate the applicability of the proposed model. The results show that the improved Shapley value is significantly enhances the multi-party cooperation and can be used as an effective tool for fair and reasonable allocation of private charging pile sharing project.
