摘要
不考虑换电仅以充电模式为研究对象,构建多级新能源供给单业态服务链,以下游的新能源有效需求量作为模糊变量,建立基于需求量随时间变动的新能源供给单业态服务链模糊需求模型和利润模型。结果表明,设计的契约增强了新能源供给单业态服务链的协调性,并随着下游有效需求量的增加,服务链中各参与主体的模糊期望利润呈增长态势,且最优契约数量逐级增大;最终,终端用户的最优契约数量与整个服务链进行集中决策时最优契约数量基本一致。
Charging mode is the research object without battery swapping,this paper constructs a multi-level single-format service chain of new energy supply.The effective demand of the downstream new energy is taken as a fuzzy variable in this paper,and the fuzzy demand model and profit model for single-format service chain of the new energy supply are established based on the demand change over time.The research shows that with the increase of the effective demand of new energy,the fuzzy expected profit of each participant in the service chain is growing,and the optimal contract quantity of the electric power supplier,the charging pile operator and the end user is increased gradually;Finally,the optimal contract quantity of the end user is basically the same as that of the optimal contract when the whole service chain is centralized decision-making.
