Design And Implement Farm Produce Traceability Model Based On Electronic Transaction

Along with the continuous farm produce quality and food safety incidents from 1970s, the quality and food safety is becoming more and more widely attention. Traceability system of farm produce can effectively reveal and transfer information. So, traceability system is gradually applied in farm produce quality control systems. The implementation of traceability system of farm produce is necessary to improve life quality and ensure food safety, the importance of researching and applying traceability system of farm produce is growing more important. Especially in the age of rapid development of electronic commerce, electronic transaction prevail by the time passed, how to solve information asymmetry effectively, and to ensure safety of farm produce in electronic transaction, is one of the problems to be solved in carrying out electronic commerce of farm produce.So far, many countries carry on the exploration, and acquire preferably effect, and the successful experience given to us has very necessary and important to study, promote and apply farm produce traceability system. First, this thesis collect and arrange the experiences of farm produce traceability system in foreign developed countries, and then analyze the enlightenment given to us on farm produce traceability system construction at home.Secondly, from the farm produce characteristic itself, analyze the information asymmetry problem on agricultural market, which is the important factor lead to farm produce quality and food safety, and give out relevant solutions. Then game theory was used to analyze the factors to influence firm's determination on establishing traceability system from point of economics system analysis, also simply stated the economic entities, which was related to the implementation of farm produce traceability system, and the cooperative relationship between them.Take thesis's background as starting point, based on the present situation on the current applied aspect, that is respectively independent and unable to interoperate, design the sharing model of farm produce traceability system based on electronic transaction, which fully integrate the existing traceability data and system, and also can avoid wasting resources on human, material resources and others wasted caused by duplicate construction in some degree.Finally, according to basic procedure of software development, fully integrate various modern software design techniques, and many key technologies, such as the individual identification technology of farm produce, data organization technology, data access technology, data exchange and transmission technology, at last realize the convenient and accurate traceability about the agricultural products deal with in the economic transaction platform.Based on electronic transaction, this thesis design the sharing model of farm produce traceability system and the method on individual identification of farm produce,propose the definition format of traceability data by means of XML Schema and method on traceability data access based on bill of Lots.Some key technologies mentioned in this thesis, especially individual identification and data organization, not very mature yet. However, that is a very good reference for further research on the application about farm produce traceability system. In addition, the implementation of farm produce traceability system based on electronic transaction, has promoting effect for the development of farm produce electronic commerce.
