Construction of Workflow Management System Modeled by Roles

The method of modeling workflow driven by roles is put forward in the paper. The workflow model is formalized defined as 4-tuple <R, T, f, D>. The key technology of workflow system construction based the present method such as: data object, authority, modeling environment and method of schedule are explicit illustrated. The function architecture of workflow system constructed by the given modeling method and the deployment architecture based on J2EE are also given in the last section of this paper.
