基于区域事件日志的过程挖掘方法研究

Research on Process Mining Based on Region Event Log

过程挖掘是从事件日志中运用挖掘方法得到过程模型。已有的挖掘方法在处理大量事件日志上还存在一定的局限性,提出一种基于区域日志过程挖掘方法,首先根据事件日志间任务的可达性分为不同区域,在此基础上将不同区域日志转化为间接继承矩阵再对应Petri网,建立区域过程模型;然后,将各个区域进行融合,得到完整的过程模型。最后,通过分析建模实例验证算法的可行性。

The mine model of process is gained by mining method from event log. With the limiting from exsiting mining method,it is difficult to dealing with a large number of event logs. In this paper,a mining algorithm based on regin log is proposed. Firstly,according to the accessibility of task between different event logs,the different regio logs are transformed into indirect inheritant martrix. The complete model can be got by mixing them together. Finally,the effectiveness of our model is verified through analysis.
