Research Of LCA System For Product's Environmental Impact Based On ERP Mechanism

With the development of industry and population's proliferation, in the face of the pressure of serious global ecological environment day by day, the environmental management demands of enterprises are more and more urgent. As the appraisal tool of environmental impact of whole product's life cycle– Life Cycle Assessment (LCA) is paid attention to day by day.But present LCA still has much limitation. Among them one of the most important points is the quality of the inventory data. The inventory data of most LCA researches at present are all got according to the ways, such as typical craft, average level or estimating, etc. The collection of these data are finished by hand, and cause the inaccurate of these data and a large amount of repeated input of manpower and material resources. In addition, at the LCA stage of impact assessment economic factors of enterprises should be considered.The system of ERP (Enterprise Resource Planning) is an integrated system that collects, analyses and controls all correlative data about enterprise's activities. So LCA can be implemented based on the mechanism of ERP system. However, existing ERP system can not apply to LCA directly. A lot of data of inventory analysis are unable to get or incomplete in existing ERP system, so these data must be revised or combined.The research works of this paper include the following several respects mainly:1) This paper, on the foundation of systematic analysis, puts forward product's LCA model based on the mechanism of ERP system, and carries on research to its systematic structure and data model.2) To common LCA environmental impact assessment, the economic factors are not considered. As to this, this paper puts forward the method frame of environmental efficiency assessment, and adopts a multi-criterion fuzzy assessment model to analyze.3) Because LCA faces the whole life cycle of product, the environmental data of raw materials and substances of the stage of before production are very important too. So the game relation between purchasers and suppliers come into being. To this kind of relation, this paper sets up game model of both sides, and makes some analysis.
