摘　　要：疫情防控期间,为了充分发挥发热门诊的作用,提出了基于Petri网的发热门诊流程模型优化分析。首先,根据发热门诊的实际情况,通过库所与变迁之间的交互关系,用绘图软件Microsoft Visio构建了发热门诊流程的Petri网模型;然后,对构建的初始模型进行分析,发现模型中存在交叉感染、资源浪费的问题。论文通过改变Petri网之间的行为轮廓,对模型做出适当调整,进行优化。最后,对优化后的模型通过PIPE软件进行仿真模拟,验证其有效性。The optimization analysis of fever clinics process model based on petri network is presented to give full play to the role of fever clinics during the period of epidemic prevention and control.Firstly,according to the actual situation of fe-ver clinics,the petri network model of fever clinics process is built by using Microsoft Visio software through the interaction between places and transitions.Then,the problem of cross-infection and waste of resources is discovered by analyzing the initial model.The model is optimized by changing the behavior profile between petri nets.Finally,the optimized model is simulated by PIPE software to verify its validity.
