Making YAWL and smartPM interoperate : managing highly dynamic processes by exploiting automatic adaptation Features

In the last years, the trade-o between exibility and sup-port has become a leading issue in workow technology. In this paperwe show how an imperative modeling approach used to dene stableand well-understood processes can be complemented by a modeling ap-proach that enables automatic process adaptation and exploits planningtechniques to deal with environmental changes and exceptions that mayoccur during process execution. To this end, we designed and imple-mented a Custom Service that allows the Yawl execution environmentto delegate the execution of subprocesses and activities to the SmartPMexecution environment, which is able to automatically adapt a processto deal with emerging changes and exceptions. We demonstrate the fea-sibility and validity of the approach by showing the design and executionof an emergency management process dened for train derailments.
