Formally Modeling and Analyzing Data-centric Workflow using WFCP-net and ASK-CTL

Despite the abundance of workflow analysis techniques from control-flow perspective, there is hardly any method for workflow verification from data processing perspective. In this paper, we restrict the WFCP-net, a Colored Petri Net with WF-net structure, to formally describe the key business entities in a data-centric workflow model. Then, we use ASK-CTL logic to describe the workflow requirements on business data processing perspective. The model checking method is adopted into our verification approach, which can explore some of the business contraventions of data perspectives in the workflow models. The effectiveness of our works has been validated with the CPN Tools.
