Research on grey correlation analysis for cleaner production

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.
