Abstract: Based on ontology theory, this paper addresses a novel workflow model that can accommodate the change of personnel and operation. To achieve the object of adapting to change more powerfully, the model adopts the method of extending the definition of conceptions and relationships inside the submodel as well as betweenthe submodels. To address the result of reducing the negative impact on the model relationships and structure, the model makes the organization, the roles and the personnel separately at different levels in the organization model. And the authority assignation model adopts the authority assignation based on task. Consequently, it also addresses the result that the change of task will not affect the organization model and will avoid the change of the complicated relationships. Especially, it makes the conception represented by ontology. Therefore, this paper produces the conclusion that the model has covered the defect of unshared feature in traditional models, at the same time, it is more secure and flexible.
