提出将全自动免疫分析检测设备看作一种可重入的双臂自动组合设备。采用时间着色的Petri网(TCPN)对该类检测设备的检测过程进行建模,并利用CPN tools评价模型性能及仿真实验。为优化检测过程,设计了DPC动态投料策略和LSPON、FIFO调度策略,并综合两类策略提出复合控制策略对TCPN模型进行调度求解。针对不同规模的批量检测项目实例在CPN tools平台上结合提出的不同策略进行调度。仿真结果验证了TCPN模型与所提出策略相结合调度方法的合理性。
It is proposed that the automatic immunoassay testing equipment be regarded as a kind of reusable dual arm automatic combination equipment. The time-stained Petri net (TCPN) was used to model the testing process of this kind of testing equipment. The performance of CPN tools and the simulation experiment were evaluated. In order to optimize the testing process, DPC dynamic feeding strategies and LSPON and FIFO scheduling strategies are designed. Combined with two kinds of strategies, a composite control strategy is proposed to solve the TCPN model. According to the different size of the batch inspection project examples in the CPN tools platform combined with the proposed different strategies for scheduling. Simulation results verify the rationality of the TCPN model combined with the proposed strategy scheduling method.
