Application Of Gray Relation Analysis To The Selection Of Cleaner Production Plans

The cleaner production is not only an environmental strategy, but also a systematic engineering. As for production process, the enterprise implements the cleaner production technology plan to reduce the consumption of energy and the raw material, enhances the efficiency of resources exploitation and reduces the discharge of pollutant, in other words the enterprise finally achieves the economic efficiency, the environment efficiency and the social efficiency unification through the implementation cleaner production technology plan. In order to achieve the the goal of cleaner production, there exists several proposals, but it's of significance how to select a proposal which is practical and brings in remarkable economic efficiency and environment efficiency under the limited condition of financial, physical and human resources. Because every aspect of a business is involved in cleaner production technique and a great many of factors should be concerned, when it comes to appraisal, the appraisal method adopted should can handle multi-layer and multi-attribution and ensure the objectivity and science nature to reduce or avoid the influence of subjective preference on results. The entire appraisal result should be able to manifest the technology progress and the unification of economic efficiency and environment benefit of the selected plan. The appraisal of the cleaner production plan is critical to the verification of cleaner production. Although at present there are many companies starting the experiment of cleaner production, there is hardly related theoretical research on cleaner production proposal, which cannot live up to the actual practice. Concerning concrete cleaner production practice and applying a gray relation analysis method, the paper works on theories of the appraisal of cleaner production plan to provide the method for the further decision-making.
