碳排放约束下的随机需求供应链库存模型研究

Research on Supply Chain Inventory Model Under Random Demand in View of Carbon Emission Regulations

从供应链领域的视角,构建碳排放税和碳排放权交易机制下的随机市场需求的供应链库存控制模型,分析碳排放税价格及碳排放权交易价格对供应链的最优订货量及其利润的影响,并对模型进行数值仿真分析.数值仿真研究结果表明:随机市场需求的波动越大,供应链订货量越高,供应链利润越低;碳排放税价格越高,供应链订货量以及供应链利润越低;碳排放权交易价格越高,供应链订货量越小,供应链利润越高.比较碳排放税和碳排放权交易机制知,碳排放权交易机制下的供应链订货量及利润高于碳排放税机制下的情况.研究成果可为减少供应链碳排放、增加供应链利润提供重要的理论借鉴.

The supply chain inventory control model has been established in which demand is random under the trading mechanism of carbon tax and carbon emission from the point of supply chain. The impact of the price of carbon tax and carbon emission trade on the optimal order quantity and profit has been analyzed, and the numerical simulation has been done. The results show that： with the fluctuation of the market demand getting larger, the order quantity of supply chain is higher, but the profit of the supply chain is lower; With the price of carbon tax getting higher, both the order quantity and profit of supply chain are lower; With the price of carbon emission trade becoming higher, the order quantity of supply chain is lower, but the profit of supply chain is the higher. If the other conditions are unchanged, the order quantity and profit of supply chain under carbon emissions trading mechanisms are higher than that of the situation under carbon tax mechanism. The research will provide important theoretical reference for reducing supply chain carbon emission and increasing supply chain profits.
