Dynamic modeling method of flexible workflow based on expanded ECA rule and its application

Traditional workflow system is not able to meet the need of dynamicity and adaptability. This paper proposes a dynamic modeling mechanism of flexible workflow based on expanded Event-Condition-Action (EAC) rule. The mechanism can be used to dynamically construct workflow model including cycle logic and build up one adapted to the requirement for E-government system flow. Finally, we give a practical example about Hebei science & technology awards evaluation system to demonstrate the validity of this method.
