Modeling Method of Traceability System based on Information Flow in Meat Food Supply Chain

摘要

Over the last decades, the food safety issues become more and more important, such as BSE crisis, genetically modified organism (GMO) illegal spreading and melamine-contamination event. The food industry established a traceability system to reduce the impact of food safety issues, and the system became an effective method of guaranteeing the food safety. The purpose of this paper is not only does the traceability system traces the process information but also reduce the batches of recall. We study the traceable information flow and risk transmission throughout food supply which contains raw material, process and distribution. A mathematic model based on dynamic programming was proposed to solve the risk transmission problem in a China dumpling factory, and Radio Frequency Identification (RFID) is used to identify and transfer traceable information in this study. The results show that factory can plan the produces schedule effectively according the mathematic model to decrease redundancy of information, and the information flow model is the fundament of traceability system. Applying of RFID system can enhance the ability about information gathering and transmitting.
