基于混合型事件日志的模型合规性检验方法

Conformance Checking Method Based on Hybird Event Logs Model

信息系统记录的事件日志多为包含点事件和区间事件的混合型事件日志,针对现有合规性检验方法不能直接应用于此类事件日志的问题,提出一种对混合型事件日志及对应模型进行合规性检验的方法,从拟合度、精确度、和简洁度三个方面来衡量混合型事件日志及其对应的过程模型的契合程度,用户可对三个指标设置权重,求出一个综合的合规性指标。论文设计并实现一个原型工具,通过案例分析说明了算法的有效性。

Considering that the event logs recorded by information systems are mostly hybrid event logs containing point events and interval events,and existing conformance checking algorithms for process mining all aim at analyzing logs contain point events,a conformance checking method for point and interval event logs and corresponding process models is proposed,which uses three indicators to measure the conformance of the hybrid event log and its corresponding process model,namely,fitness,precision and simplicity.Users can set weights on the three indicators to obtain a comprehensive conformance index.A prototype tool is de⁃signed and implemented,and the effectiveness of the algorithm is illustrated through case analysis.
