The Design And Research Of LCA Database Management System And Case Study

Life Cycle Assessment (LCA) is an environment management tool and thought brought forward by the series of ISO 14000 Standards for environment management, which has griven significance to raise the level of environmental management and realize the sustainable development in the end. In order to make LCA system more fittable to the Chinese environmental character,the article has researched the software system of LCA that is applicable to the situation of China. At the same ,the software system of LCA adopts the environment norm of China.First,on the foundation resuming backgrounds,present situation and developing tendency of the issues' research,the paper analyzes the technological framework of LCA,and with software engineering and Object-Oriented (OO) thoughts and methods as direction,designs the structure of the system LCA.Second,the article has researched the data-prepare and the assessment measure that are included in the data management system of LCA,and prescribed the data-link mode.At the same time,on the basis of the foundation data abstracted from China contamination emissions and policy layout during 1995~2005 year,the article has empoldered a suit of LCIA method which is applicable to the situation of China.This method is adopted by the system as the main method..Third,the data management system of LCA is a kind of windows application sofeware developed by Visual Basic 6.0 language connecting the powerful database tool (mySQL) .The program design carried out by the open Database Connectivity (ODBC) and Structured Query Language (SQL) to directly access and provide basic database operation. The system is characteristic of wide selection of data sources, rational design of data structure, automatic querying for information from diferent aspects and high visual level and beter expending. It also has the same style as windows browser.And it's easy for users. As a part of LCA database, this programme will be benefit to the development of software in LCA.Lastly,the use of the developed system is illustrated with the internal fuel vehicle carring trade.the syetem is used to compare several kinds of impact types.In order to provide the project decision-maker with the assessment gist in the environment, direction.
