Coupling Coordination Degree Model of Supply Chain Partners

Based on the viewpoints of synergistic theory and the concept of coupling, this paper establishes coupling degree model of interaction between supply chain partners. Furthermore, it puts forward coupling coordination degree model which includes efficacy function, coupling degree function, coupling coordination degree function. This paper also establishes and analyses indicator system of supply chain partners relationship on the basis of the example, analyses the development and change of the coupling between supplier and manufacturer- a two-level supply chain, and provides quantitative decision-making basis in order to maintain and improve supply chain partnership. Finally, it proposes some suggestions for the future research.
