双积分制下汽车生产商生产决策优化

本文研究了燃料消耗量积分和新能源汽车积分"双积分制"下汽车生产商生产决策问题,基于持股比例和内部期权协议建立了传统能源车与新能源汽车联合决策模型,在积分不足、积分富余和积分平衡三种策略情形下求解了最优定价、产量和内部积分协议价,并针对市场积分价格和汽车销售量的实际波动求解了生产计划的鲁棒区间及其应急调整策略.研究结果表明:持股比例主要影响内部协议价形成,持股比例越高,内部协议价越趋近于外部市场价;初始生产计划存在多维非对称鲁棒区间,汽车生产商可通过价格响应机制实现生产计划扰动管理及积分策略切换;控制积分交易限量将改变最优生产计划及其应急调整策略.

Optimal production decision of vehicle manufacturer based on double-score system

This paper aims to investigate manufacturer vehicle production decision based on "double score system" considering both fuel consumption score and new energy vehicle score. We first develop a joint decision model for conventional fuel and new energy vehicle production based on share proportion and internal option agreement. The optimal solutions to pricing, production and internal negotiated score price are then resolved considering three different strategies including score deficiency, score surplus and score balance. As a follow-up, we also investigate robust range of initial production planning and its emergency adjustment strategies according to variation of score market price and vehicle sales. The results demonstrate that share proportion significantly affects the formation of internal negotiated score price; specifically, the higher the share proportion is, the closer the internal score price would be to external market score price. Results also indicate that there is a multi-dimensional asymmetric robust range for the initial production planning, and that vehicle manufacturers are able to realize the switch among different production management strategies using price responding mechanism. Finally, it is also found that limiting score trading would considerably affect optimal solutions.
