Abstract: Workflow mining is a key technology in workflow re-design and analysis field. It is generated to improve the objectivity of workflow modeling by extracting the actual business related process from records of the running informalion systems in enterprises. However,most of Workflow Mining methods are based on records of information systems running in companies. On the other hand, they have bad performance in mining complex tasks and flexible workflow. To solve those problems, we proposed a Dynamic Workflow Mining model. In this model, there is no record from the beginning,workflow nets and records were dynamically generated. The given example was used to demonstrate improvements on model accuracy and description ability of the proposed algorithms.

Key words: Dynamic workflow, Workflow mining, Workflow net
