Uncertain Marking for Dealing with Partial Parallelization in Business Processes

In this paper, an approach based on WorkFlow nets and possibilistic Petri nets is proposed for dealing with flow deviations in business processes. Routing patterns existing in business processes are modeled by WorkFlow nets. Possibilistic Petri nets with uncertainty in the marking and the transition firing are considered to express in a more realistic way the ordering of human activities during real time execution of the process model. Combining both formalisms, a kind of possibilistic WorkFlow net is obtained. An example of flow deviations due to human behavior at a process monitoring level is presented
