模糊数学评价方法应用于包头混合型稀土精矿冶炼企业清洁生产评价指标体系制订

Application of Fuzzy Mathematics Method on Establishment of Clean Production Evaluation Index System in Baotou Mixed Rare Earths Concentrate Enterprises

  • 摘要: 评价指标的合理分级是行业清洁生产评价指标体系构建的难题,采用模糊数学评价方法对包头混合型稀土精矿冶炼业清洁生产评价指标体系制定过程中的指标进行分级。结果表明,该方法可以改变单一指标之间的比较评估为整体性评估,使某一评价对象的生产工艺及装备指标、资源能源消耗指标、资源综合利用指标、污染物产生指标、产品特征指标和清洁生产管理指标等6类指标经过隶属度计算得出一个综合评价结果,经计算得出多个评价对象的综合排序,使分级结果更加科学、合理,更有可操作性,对于指导其他行业清洁生产评价指标体系的制订具有很大的现实意义。

     

    Abstract: The reasonable classification of evaluation indexes is a problem for the establishment of the index system of cleaner production. The fuzzy mathematics assessment method was used for indicator classification in the establishment of clean production evaluation index system of Baotou mixed rare earths concentrate industry. The results show that, instead of comparison among single indicators, the holistic assessment combines indicators of production process and equipment, resource and energy consumption, pollutants generation, product characteristics and cleaner production management, presents an integrated result by the fuzzy subordination, and obtains synthetic ordering of multiple evaluation objects. This kind of method makes the grading result more scientific, rational and objective, which is practical for the establishment of clean production evaluation index systems in other industries.
