Implementation of Policy Based Management in Workflow Management System

摘要

The foundation of a traditional workflow management system is process-based management. We have proposed to integrate policy-based management in workflow management systems to improve the flexibility and the dynamic behavior. In this paper, how to implement policy-based management in a workflow system is discussed. To construct policy model, a meta modeling method with four layer structure is introduced. The main tasks in each layer of the meta modeling architecture are described. To define where and when to apply policies in a workflow, a Control Point model is introduced. A workflow process meta model supporting policy-based management is presented. The architecture of a simple prototype system to support policy based management is also presented. The new approach has better flexibility in design time and higher adaptability at run-time.
