Supporting the evolution of process model at run-time stage and propagating the changes of process model to the active process instances are fundamental requirements for any flexible process-aware information systems(PAIS).Instance migration is regarded as the mainstream technique that deals with the dynamic evolution of process-aware information systems.By using this technique,active process instances are migrated to the modified process model,so that they can benefit from the optimization process.The chal...
