Abstract:
The business process must reflect changes in the environment, therefore, the adaptation of the process model or the particular process instance is essential. The state compliance criterion has been introduced to check that dynamic process change is correct and does not lead to soundness problems or run-time errors. In some cases, however, the process instance must immediately be migrated to the changed model or updated itself. Hence, the strategy of coping with the non-compliant process instance must be chosen. This paper presents the process re-execution approach which effectively implements the state compliance test. The reexecution algorithm makes it possible to defer the suitable activities and use them later, thus offering a flexible solution for treating the non-compliant process instances. Moreover, a custom strategy of treating can be used based on the full context of the activity that caused the inconsistency. In many cases, the process re-execution approach enables to treat the non-compliant process instance automatically and thus the total number of instances that are successfully migrated is increased.
