【摘要】：针对生产过程不完美并且考虑将次品返运回生产方的二级闭合供应链系统,基于所有参数和决策变量均为梯形模糊数的情景,研究如何利用碳限额与交易机制实现对供应链总成本与碳排放的有效管理.建立供应链模糊总成本与碳排放优化模型,利用梯级平均综合表示法和Kuhn-Tucker条件法求解得到经济订货量、最优总成本和最小碳排放.结果表明:模糊参数相对于确定参数的不同方向与幅度的变化会导致差异较大的决策结果;次品率对总成本的影响与生产率和碳限额的影响方向相反,碳价对总成本的影响受给定碳限额的制约;次品率降低、生产率和碳价提高会降低碳排放,碳限额对碳排放无直接影响.
[Abstract]:The production process is not perfect and consider the two level of closed supply chain system defective recurrent back production side, based on all the parameters and decision variables are trapezoidal fuzzy number situation, study how to use carbon cap and trade mechanism to realize the effective management of the total supply chain cost and carbon emissions. The establishment of supply chain and fuzzy total cost the optimization model of carbon emissions, using graded mean integration representation method and Kuhn-Tucker method to solve the economic order quantity conditions, the total cost optimal and minimum carbon emissions. The results show that the fuzzy parameters relative to the change of different parameters to determine the direction and magnitude of the decision will lead to different results; the defective rate influence on the total cost and productivity and the carbon cap in the opposite direction, impact on the total cost of the carbon price is restricted by a given carbon limit; reduce the defective rate, productivity and carbon price increase will reduce carbon emissions, carbon limit The amount has no direct impact on carbon emissions.
