基于复合渠道回收的闭环供应链决策模型研究

Research on Decision-making Model of Closed-loop Supply Chain Based on Composite Channel Recycling

研究了复合渠道回收的两级闭环供应链系统决策问题。在只有零售商负责回收的再制造闭环供应链上增加了一条由制造商直接回收的渠道,组成复合渠道回收,建立相应线性数学模型,并分别求出两种情况下供应链合作的最优价格决策和制造商占主导的非合作博弈最优价格决策。通过分析比较结果显示,在假设条件下无论是合作还是非合作情况下,复合渠道回收不会影响正向供应链的最优定价及其相应需求,但回收量一定会增加,市场固定回收量a=0时利润一定会有所增加,反之只有在满足一定条件时利润才会相应增加。另外,不同的条件下两种情况利润增加有多有少。最后给出数值分析。

This paper studies the two - stage decision - making model of closed - loop supply based on composite channel recycling. On basis of this, it adds another direct recycle channel by manufacture to the traditional reproducing closed - loop supply chain only with on recycle channel, then it builds the two different mathematical models and obtains non - cooperative game equilibrium and the cooperative game equilibrium. Based on comparative analysis, it comes to the conclusion that： the new channel will not influence the optimal strategy of the positive - going supply chain and the amount of recycling will be increased. When a = 0, the profit will be increased, conversely, the profit will be increased on the special condition; besides, under different conditions the two different kinds of profit increases are different. At last, it puts forward numerical analysis.
