Analysis of Workflow Drived by Role and Application of UML-uc Modeling Technology
角色驱动下的工作流分析及UMLuc建模技术的应用*

Based on the research of workflow,directed graph and UML-uc,a directed graph-based workflow modeling(me-)(thod),driven by role whose mechanism is investigated in the workflow,is put forward.The essential idea is that delaminating and refining the workflow modeling to the atomic activities conformed to the role,the UML-Use case model of the system which depicts the refining course and some UML-Use case models of roles including static,competitive,priority-ranked and commitment models are provided.The paper also explores the complicated dynamic relation within the model in virtue of role participative mechanism and dynamic characteristic of Use-case models.Furthermore,according to the result,the paper attempt to develop the latter part of the model that is more complicated than the former to a more efficient way.
