利用AHP-BP法建立水泥企业循环经济评价指标体系的研究

THE ESTABLISHMENT OF CEMENT ENTERPRISE CIRCULAR ECONOMY EVALUATION INDEX SYSTEM BY UTILIZING AHP-BP METHOD

作为典型的"两高一资"行业,水泥行业的资源环境约束日益凸显,可持续发展面临严峻挑战。循环经济作为一种建立在资源节约和循环利用基础上的全新经济发展模式,其生产的基本特征是低消耗、低排放、高效率,业已成为水泥工业实现资源能源节约、污染源头削减、废物综合利用、降低环境负荷,实现可持续发展的必由之路。从资源产出、能源消耗、资源综合利用、污染排放及产品质量五个方面选择了18个指标,利用AHP-BP(层次分析法-反向传播神经网络)组合模型,建立了水泥企业循环经济评价指标体系,用于全面评价水泥企业循环经济发展水平。最后引入制约因子概念,并结合该模型进行实例研究,探讨研究对象下一步开展循环经济的工作方向。

Due to the 'two high one capital'feature,resources and environment constraints become more emerging in the cement industry,which leads to severe challenge in the sustainable development. As a new kind of economic development model,circular economy aims to realize a low consumption,low discharge and high efficiency,has become an effective way to achieve sustainable development in the cement industry,such as the resource conservation and reducing pollution sources and environment load. The study selected 18 indicators to evaluate the development level of circular economy for cement enterprises comprehensively,which can be classified into five kinds such as resource output index,energy consumption index,resources utilization index,pollution emission index and product quality index. By means of AHP-BP model( analytic hierarchy processback propagation) an evaluation index system was set up. Finally,the evaluation index system was used to evaluate the level of circular economy development in a typical cement enterprise,and the result of assessment agreed with the actual conditions. In the process of evaluation,the concept of restriction factor was introduced creatively,which can show the direction clearly of circular economy work for the cement enterprise in future.
