基于AHP-Fuzzy方法的铝酸钙企业清洁生产评价指标体系构建

Construction of Evaluation Index System for Cleaner Production of Calcium Aluminate Enterprise Based on AHP-Fuzzy Method

铝酸钙主要用于生产铝盐产品,其尤为突出的作用是决定水处理剂聚合氯化铝的性能优劣,为了更好的控制铝酸钙的生产,方便企业实施清洁生产和强化环境管理,构建清洁生产评价指标体系是重中之重。通过对铝酸钙企业的整个生命周期进行调查分析,结合国家清洁生产评价指标体系编制通则、其它行业清洁生产评价指标体系及专家经验,运用层次分析法建立铝酸钙企业清洁生产评价指标体系,确定一级、二级各项评价指标的权重;根据国内外铝酸钙企业先进的清洁生产模式及专家的建议确定各评价指标的等级基准值;运用模糊数学综合评价法确定综合评价的方法。同时对国内一家较先进的铝酸钙企业进行实证分析,取得了一致的结果,因此该评价指标体系能全面、科学、合理地反应铝酸钙企业的清洁生产水平。

Calcium aluminate is mainly used to produce aluminum salt products. It is particularly prominent role is to determine the performance of water treatment agent poly aluminum chloride pros and cons.In order to control the production of calcium aluminate better,to facilitate the implementation of cleaner production and strengthen environmental management,construction of cleaner production evaluation index system is the most important. By the calcium aluminate enterprises throughout the life cycle of investigating and analyzing,combined with the general rules of the national cleaner production evaluation index system,other industries of cleaner production evaluation index system and expert experience,the evaluation index system of cleaner production of calcium aluminate enterprises was established by using analytic hierarchy process. The weights of the first and second evaluation indexes were determined. According to the domestic and foreign enterprises advanced calcium aluminate clean production model and the recommendations of experts,to determine the level of the evaluation index of the benchmark value. The method of comprehensive evaluation was adopted by using fuzzy mathematics comprehensive assessment method. Meanwhile,an advanced calcium aluminate enterprise participated to carry on the empirical analysis,while achieving consistent results. Therefore,the evaluation index system can be comprehensive,scientific and reasonable response to the level of cleaner production of calcium aluminate enterprises.
