Evaluation Model of Building Materials Suppliers Considering Carbon Emissions

Abstract

In the study of AHP and grey relational degree model, this paper establishes four secondary indicators such as product competitiveness, enterprise performance, enterprise cooperation ability, enterprise environmental assessment and twelve tertiary indicators. Then the weight index system is determined by using the analytic hierarchy process, and the warrants of environmental assessment are added considering carbon emissions and other factors. Last the grey correlation analysis is used to determine the supplier correlation. In this paper, the mathematical model is used to carry out an example analysis, so as to evaluate suppliers, and then select low-carbon, economic, high-quality suppliers.
