The errors of data inconsistency occur in a concurrent system when some concurrent operations are conducted improperly. The model-checking technique is widely used to detect them based on the state transition graph. However, the state space explosion problem is the biggest obstacle for this technique, since the state transition graph is based on the interleaving semantics that can result in a rapid...
Soundness is an important property of WF-net (workflow net). It guarantees the correct execution of workflow systems without deadlocks or livelocks. The traditional method of verifying soundness is based on reachability graph. However, it suffers from the state space explosion problem. The unfolding technique of Petri nets can effectively alleviate this problem. Our previous work proposed the concept...
