【摘要】：射频识别技术(Radio frequency identification,RFID)在制造过程跟踪中得到了广泛应用。目前RFID的应用研究仅适用于具体的场景,缺乏通用性的建模和形式化的描述方法。针对上述问题,提出一种基于RFID的过程跟踪形式化图式推演建模方法。通过对广义单工序活动进行多粒度分解,形成单工序作动时序单元模型;在此基础上,定义四种通用的RFID探测模式并建立图式状态block模型,构建图式描述的单工序RFID过程跟踪监控时序流;借助Gantt图分析广义单工序作动时序单元的"串联-并联-条件"连接,建立多工序RFID过程跟踪模型,为生产、物流、库存等的全过程跟踪提供依据。以机加工车间高价值刀具流转过程、Job-shop零件加工过程以及零件外协加工过程的跟踪三个应用场景为例,验证了该模型方法的可行性和通用性。
[Abstract]:Radio frequency Identification (RFID) is widely used in manufacturing process tracking. At present, the application research of RFID is only suitable for specific scenarios, lacking of general-purpose modeling and formal description methods. To solve the above problems, a formal schema modeling method for process tracking based on RFID is proposed. Based on the multi-granularity decomposition of generalized single-process activities, a single process actuation sequential unit model is formed, and four general RFID detection modes are defined and schematic state block models are established. This paper constructs a single process RFID process tracking and monitoring sequential flow described by schemata, analyzes the "series-parallel-condition" connection of generalized single-process actuating sequential unit by Gantt diagram, and establishes a multi-process RFID process tracking model for production and logistics. The whole process of inventory tracking to provide the basis. Taking the three application scenarios of Job-shop machining process and part coprocessing process tracking as examples, the feasibility and generality of the model method are verified.
