Topic status: We're looking for students to study this topic.

Process model repair refers to the following problem: Given an event log of a process-aware information system that does not fit to a process model, automatically transform the model such that the event log fits the transformed model better than it fits the original model. Thus, process model repair allows keeping models of process-aware information systems in sync with observed process instances by suggesting mechanisms for reflecting traces encountered in event logs in executions captured in corresponding models.

The study of the problem of process model repair is an integral part of our broader research program on design of automated methods for management of process knowledge within organisations.

Current research interests in process model repair include:

  • impact-driven process model repair
  • techniques for process model repair
  • quality metrics of process model repair
  • empirical studies on process model repair.
