灰色关联度分析法用于清洁生产的方案研制

Research on grey correlation analysis for cleaner production

针对中国清洁生产审核方案研选存在的不足,运用灰色关联度分析法,构建清洁生产指标体系,并将经济指标、环境指标及技术指标量化细化,再与评价标准对比进行分析评判,最后选出与评价标准关联度最大的方案作为最优方案。通过重庆某水泥厂案例研习,证明灰色关联度分析法用于清洁生产方案研选可有效避免人为主观偏好影响,使研选出的清洁生产方案更科学、公正,各项指标更好。

The current methods used to select the schemes for Cleaner Production in China have some disadvantages. This paper presents the Grey Correlation Analysis and constructs a new index system for Cleaner Production schemes. The environmental index, the economic index, etc. , and technical index, are quantifyed and minimized. Each scheme is compared with the evaluation standard. The optimal scheme which has the largest correlation with the evaluation standard. The result shows that the Grey Correlation Analysis can effectively avoid the subjective bias on the scheme selection for Cleaner Production. Schemes for Cleaner Production selected by the Grey Correlation Analysis have better performance than those selected by the traditional method in terms of economic, environmental and technical indexes.
