Iron and steel enterprise green degree evaluation method based on AHP-entropy

Abstract

The invention relates to the technical field of enterprise green degree evaluation, in particular to an iron and steel enterprise green degree evaluation method based on AHP-entropy. The method comprises the following steps: constructing an iron and steel enterprise green degree evaluation index system comprising a target layer, a criterion layer and an index layer according to an AHP principle, standardizing original index data, calculating a subjective weight of each index through an AHP method, calculating an objective weight through an entropy evaluation method, calculating a combined weight and carrying out green degree comprehensive evaluation; the invention introduces the concept of green degree, establishes a set of simple, scientific and quantifiable iron and steel enterprise green degree evaluation method, proposes twenty-five representative indexes based on a green degree total target and according to the characteristics of the iron and steel enterprise by taking four dimensions of material consumption, energy consumption, pollutant discharge and recycling as criteria. In order to inspect the important new size of different indexes for the upper layer of target and overcome the defect of a single method, the judgment result can be better matched with the reality, and the method is more scientific and reasonable.

Description

Technical field[0001]The present invention relates to the technical field of enterprise greenness evaluation, and in particular to a greenness judge method based on AHP-entropy-based steel enterprises.Background technique[0002]The steel industry is a multi-input, multi-output capital-intensive industry, a large number of resources and energy will be consumed in its production process, and some pollutants, waste, etc. With the deepening of green concepts, facing their high-energy and high pollution problems, government and enterprises begin to re-examine the production and management practice of steel enterprises from multiple levels, so that steel companies turn into low-energy, low-polluted green companies. To achieve a good unity of environmental and economic benefits, improve the competitiveness on the international stage. Therefore, the greenness of the steel enterprises has become an important indicator for measuring the green competitiveness of steel companies.[0003]At present...

In terms of evaluation methods, a single evaluation method reduces the reliability of the evaluation results

At present, my country has not yet formed a unified evaluation system for the green degree of iron and steel enterprises, lacks the method of evaluating the green degree of iron and steel enterprises by using AHP-entropy combination optimization, and has not formed a green degree evaluation standard for accurate comparison between different iron and steel enterprises
