The Design And Implementation Of Traceability Data Collection System For Poultry Industry

Traceability throughout the food supply chain from the farm to fork is becoming a dominant issue in the discussion of food safety and food quality guarantee. Compliance with European Union (EU) and International Organization for Standardization (ISO) regulation, permanent controlling and monitoring the product quality of the poultry supply chain are main driven forces for this system.In this thesis, poultry supply chain is modeled using Integrated Enterprise Modeling methodology developed by Fraunhofer institution. In addition, the process models within each partner of the supply chain covers the processes from fertilizer production over crop farming to broiler processing and even logistics are presented. Based on the process models of each partner and the traceability information model proposed, the critical traceability data need to be collected are identified.Unique and secure identification is prerequisite for effective traceability data collection. After introduce Global Standards 1 (GS1) identification system, the identification schema within each partner of the supply chain based on Radio Frequency Identification (RFID) tag and barcode are discussed. To guarantee highest quality of chicken meat, individual level of traceability is employed for broiler, each chicken would have a RFID tag with a unique identification number.After defined the critical traceability information and the identification schema, the thesis analyzed software requirements and bundled most important and fundamental requirements of each sub-system into the requirements of the first version, which is discussed in design and implementation chapters.Then, general design of the system is provided. The software architecture, internal infrastructure and database design are presented. Since some function requirements in different sub-system are similar, the structure of needed data is the same. For this kind of functions, reusable modules are designed. After that, detail design of the modules and testing is provided. At last, the conclusion is drawn and the possible directions of future work are discussed.
