Model of Green Evaluation Index of Petrochemical Enterprises by Consistency AHP

Abstract

Abstract AHP can be easily influenced by human subjective consciousness, which may lead to inconsistencies. So it is necessary to process AHP with mathematics methods to achieve logical compatibility. In this paper, the evaluation index model of petrochemical enterprises is constructed according to the improved consistency AHP method, so as to perform comprehensive evaluation for enterprises and strengthen the environmental pollution control. Based on the specific characteristics of petrochemical enterprises, the relevant green index model is established after the specific theoretical framework of index scoring, hierarchy and synthesis of indexes is perfected, and the indexes of green characteristics are decomposed. In order to realize the scientificity of index transfer, the power exponent with case analysis is used to calculate the specific values of indexes in this paper, and the scientifically evaluated green index which is easy to be compared is calculated, which provides the basis for policies of environmental protection in petrochemical industry.
