Coupling evaluation and optimization strategy of the Supply Chain System

The system coupling is an important characteristic of the supply chain system (SCS), and affects the stability and reliability of the SCS. The business coupling, information coupling and operation coupling are analyzed, and their coupling degree evaluation models are built also. The business coupling degree will increase by improving the product quality, increasing the information and operation coupling degree, and participating in the cooperative R&D; the information coupling degree will increase by building the information sharing flat, and standardizing the information transmission and processing; the operation coupling degree will increase by unifying the operation standard, increasing the information coupling degree, and eliminating the conflict of the operation objects in two subsystems.
