Abstract: This paper presents a set of desirable properties for process models in short form. It then presents a theory of threads of control in compact form and relates this theory to place invariants. (We have discovered a few typos in the full paper.). It shows that the main property, simple control, is closely related to the boundedness and liveness of a strongly connected free-choice Petri net.
Keywords: free-choice petri nets control properties workflow behavior.
