摘要 基于流程挖掘中的α算法和流程挖掘平台ProM(process miner),将医疗急诊流程的事件日志转化为Petri网模型,并将其与医疗急诊日志及实际流程对比分析。由于α算法的局限性,对于一些复杂结构,可能会导致错误的挖掘流程。基于逻辑Petri网,给出了一种挖掘模型的改进方法,利用逻辑变迁来避免选择结构,并进行医疗急诊流程的二次建模,进而保证构建的流程模型与实际流程保持一致。 Medical emergency event logs are modeled based on Petri nets and(algorithm in process mining and a ProM(process miner)platform.The Petri net models and the actual processes of medical emergency are compared and analyzed.Due to the limitations of(algorithm,it would lead wrong mining process when there are some complex structures.A logic Petri net-based approach is proposed.Logic Petri nets are used to avoid selection structures,and the medical emergency process is modeled again based on logic Petri nets.The new model can ensure the consistency of actual processes and the Petri net models.
