Abstract:In view of uncertainty and complexity in the process of green supply chain integrative performance evaluation,this paper used identity- discrepancy- contrary connection degree formula embodying certainties and uncertainties of the assessment system and set pair analysis model to give an integrative performance assessment to the green supply chain,based on set pair analysis theory.Through calculation,each subsystem and integrative performance assessment grades of the selected supply chain are obtained.So,a new method is provided for green supply chain integrative performance assessment here.
