摘要
提出了一种基于射频识别(RFID)的Petri网在水产品全程质量追踪和溯源系统应用的方法,以构建高效的基于物联网技术的水产品溯源与安全预警平台。根据实际水产品业务流和信息流,利用Petri网进行建模,然后在CPN Tools环境进行仿真。仿真结果表明:该建模方法简单、可行,能够验证工作流模型的有效性,而且便于计算机形式化表达和优化分析,有利于工作流管理系统的实现和性能提高,一定程度上提高了供应链的效率,从而降低了流通的成本和质量风险。
An application method of Petri net in aquatic products quality traceability system, based on radio frequency identification（RFID） is proposed, aiming at high transport costs and quality risk, etc, to construct high efficient seafood traceability and safety warning platform based on hernet of things（IoT） technology. According to actual business flow and information flow of aquatic products, modeling is carried out based on Petri nets, and simulated by CPN Tools. Simulation result shows that the new modeling method is more simple and feasible, and can validate the effectiveness of a workflow model. With this new method, a workflow model is easily formalized and optimized in computers, and it is conductive to realize workflow management system and improve performance, efficiency of supply chain is improved, then cost of transportations and quality risk are reduced.
