Optimization of Supply And Demand Matching In Supply Chain Coupling Mechanism

The mismatch between supply and demand caused by asymmetry of market information has long been an issue. This paper studies a two-tier supply chain model consisting of automaker and chip supplier with unstable supply and fluctuating prices. First, the influence of supplier’s reliability and wholesale price on manufacturer’s order strategy when supplier dominates market is analyzed. Then a set of supply chain coupling mechanisms is designed to analyze its feasibility in solving supply shortage issue. Finally, the coupling coefficient is solved to maximize the revenue of supply chain. Theoretical analysis results show that there is a threshold point for supplier’s effort cost coefficient, and when effort cost coefficient exceeds threshold point, the supply is no longer stable, and it triggers a sharp increase in supply price. This threshold point is affected by supplier’s production cost, manufacturer’s order quantity, and asymmetry of demand information. Simulation results reveal that there is always a supply chain coupling coefficient, which maximizes the total benefit of the supply chain. In this coupling coefficient, supplier’s reliability and manufacturer’s order quantity reach the maximum. Finally, compared with vertical integration, coupling mechanism is more advantageous in coordinating supply chain in the field of high-end chips
