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.

Key words: consumer electronic product, closed-loop supply chain, adaptive coordination, life cycle
