面向制造过程的钢铁企业绿色性量化评价

Manufacturing Process-Oriented Quantitative Evaluation of Green Performance for Iron and Steel Enterprise

为客观评价钢铁企业的资源效率和环境影响,有必要对其绿色性进行整体评估,并对相关指标差异性进行分析,以便更具针对性地改善钢铁企业绿色性。在构建可供量化的多层次绿色评价指标体系基础上,首先对钢铁企业中实际生产数据进行处理后得到绿色评价指标的判断值,通过判断值与行业基准值进行对比得出各项绿色指标的得分情况并反映在雷达图上,然后通过面积和周长两个评价向量量化评价钢铁企业的绿色性及其指标差异性。最后运用雷达图法对三家钢铁企业的绿色指标进行图形直观评价和数值综合评价,以便钢铁企业能够明确其在同行业中的定位,并分析其自身存在的优势与不足。首次将雷达图应用于钢铁企业绿色性及其指标差异性评价中,具有更直观的可视性,量化评估更精确。

In order to objective evaluation of resources efficiency and environmental impact of an iron and steel enterprise, it is necessary to carry out overall assessment about its green performance, and to analyze related indictors differences, so that more specifically to improve green performance of iron and steel enterprise. On the basis of constructing a quantifiable multi-level green evaluation indictors system, firstly, after processing of actual production data in iron and steel enterprises can obtain the judging value of green evaluation indictors, through compared the judging value with the industry basic values, it concluded the scores of every green indictors and reflected on the radar-graph, and then through the area and perimeter of two evaluation vector quantitative evaluated green performance of iron and steel enterprise and its indictors difference. Lastly, using radar-graph method can to carry on graphics intuitive evaluation and numerical comprehensive evaluation for the green evaluation indictors of three iron and steel enterprise, so that the iron and steel enterprises to clarify its position in the industry, and analyze the advantages and disadvantages of its own existence. For the first time applying radar-graph to evaluation of green performance of iron and steel enterprise and its indictors difference, it has a more intuitive visibility and more accurate quantitative evaluation.
