Enhance process flexibility by case-based reasoning and process mining

Current process models are hard to describe uncertain factors in applications before run-time, which results in inflexibility of Process-Aware Information Systems. For this problem, a method to achieve process flexibility by underspecification based on so-called flexible block was proposed. The flexible block is running in ad hoc manner firstly, then it's inside process structure is gotten through process mining after the running history data accumulated to a degree. And then, the application scenarios were matched, and the process model of flexible block was educed through interactive case-based reasoning. Practices indicate the approach proposed by this paper can reuse the modeling knowledge very well. Modeling efficiency of flexible block is improved along with the increase of its executing times. The business process models contained flexible blocks are with high flexibility.
