考虑碳排放约束下两级供应链生产与库存决策研究

Two-echelon Supply Chain Production and Inventory Decision under Carbon Emission Constraint

分别考虑3种碳政策约束下两级供应链生产库存决策问题。以企业的视角探究其在不同碳政策下如何决策以实现总成本最小化目标,通过对不同碳政策下的模型进行细化研究,证明了对于合作型的两级供应链在合理的碳政策下,企业可以大量减少碳排放量,且不明显增加总成本。同时在碳限额与交易政策下,随着碳价的提高,企业努力减少碳排放量的激励作用越明显。并讨论了在碳限额政策下碳限额E的上下界值,在该政策下可以严格控制碳排放量,但碳限额与交易政策下企业的生产更具柔性。最后通过数值实验验证这些结论。

To explore how to make decisions based on different carbon policies to achieve the goal of minimizing the total cost, two-echelon supply chain production and inventory decision is considered under the three carbon policy constraints.Through a detailed study of the models under different carbon policies, it is proved that for the cooperative two-echelon supply chain companies, adopting a reasonable carbon policy can significantly reduce carbon emissions without significantly increasing the total costs. Meanwhile, under the policy of carbon cap-and-trade, the carbon′s price is raising which stimulates enterprises to reduce carbon emission. Under the policy of carbon cap, it is found that the lower and upper bounds of E and the carbon emission can be strictly controlled. Also the carbon cap and trade policy can make the production of enterprises more flexible. Finally, these conclusions are verified by numerical experiments.
