不确定环境下的消费类电子产品闭环供应链的自适应协调

    Adaptive Coordination of Closed-Loop Supply Chain for Consumer Electronic Product with Uncertainty

    • 摘要: 研究了单产品多周期的消费类电子产品闭环供应链系统,面对供应链内部和外部不确定性的自适应协调问题。利用自控原理模型对整条供应链进行分析,指出了供应链脆弱性的根源所在,并在此基础上提出了带补偿的模糊自适应PID协调模型。案例研究表明,该控制策略能够增加消费类电子产品闭环供应链在产品不同阶段应对风险的能力,使系统在遇到重大风险时3周内恢复到平衡,产品的整个生命周期过程中库存量的稳态误差保持在±5%以内,且不需要增加过多的库存冗余,给供应链节省了投入,增加其收益。

       

      Abstract: The adaptive coordination problem of multicycle closed-loop supply chain for single consumer electronic product in uncertain environment is discussed. With an auto-control model, the source of vulnerability of consumer electronic product supply chain is studied. A self-adaptive fuzzy-PID coordination model with compensation is proposed. An application case is given to verify the proposed method. Result shows that the proposed model increases the response capacity of supply chain to risks at different stages of the product. The system returns to the equilibrium in only 3 weeks after encountering a significant risk. The steady-state error of inventory in the process of the entire life cycle of the product is kept in ± 5% or less. There is no requirement of excessive inventory redundancy. Thus, it makes the supply chain more efficient.
