Controlling Time-Awareness in Modularized Processes

The proper handling of temporal process constraints is crucial in many application domains. However, a sophisticated support of time-aware processes is still missing in contemporary information systems.As a particular challenge, temporal constraints must be also handled for modularized processes (i.e., processes comprising subprocesses), enabling the reuse of process knowledge as well as the modular design of complex processes.This paper focuses on the representation and support of time-aware modularized processes.In particular, we present a sound and complete method to derive the duration restrictions of a time-aware sub-process in such a way that its temporal properties are completely specified.We then show how this characterization of a process can be utilized when re-using it as a subprocess within a modularized process.
