猪肉生产加工信息追溯系统的分析和设计

针对中国畜牧业产品质量安全的需求，研究猪肉生产加工信息可追溯系统的体系结构。以国际通用物流信息标识和条码表示系统作为基础，对猪肉生产加工信息的可追溯性进行了需求分析和体系结构分析。建立了符合中国国情的猪肉生产全程追溯体系，分析了猪肉生产供应链中物流单元的个体标识和追溯信息组成，设计了物流单元在供应链各个环节上的标识载体样式；提出并分析了适用于该体系的软硬件系统结构以及生产质量控制预警机制，涵盖猪肉生产供应链的全过程；并给出了一个追溯应用范例。该体系能够将猪肉生产的信息流和实物流系统地联系起来，供应链各成员及消费者能够获取完整的猪肉生产加工信息。该体系是确保畜牧业安全生产和质量控制的有效手段。

Analysis and design of information traceability system for pork production supply chain

Aiming at the existing requirements of animal husbandry production quality safe in China, architecture of pork production information traceability system was studied in this paper. Based on European Article Numbering (EAN) and international logistics information label, requirements analysis and architecture analysis of pork production information traceability were presented. A whole process traceability system that could be applied in pork production with Chinese situation was created. The contents of traceability information and individual marking were analyzed. On this basis, the style and model of logistics unit mark and label that used in pork production supply chain were designed. The structure of hardware and software were presented. With the structure, a pre-warning system was developed, which could be applicable to the pork production traceability system. The instance analysis shows that the proposed traceability system could effectively identify the security problem in pork production, and issue the recall information. Based on the integrated and robust traceability data, the logistics information and production streams were systematically contracted. Every supply chain member and consumer could acquire the complete pork production information in this system. The system for pork production supply chain performed well and effectively.
