Abstract
Workflow management systems have been applied in enterprises for many years in collaborative environment to assist individuals or organizations to carry out tasks automatically and effectively. As market requirements are developing rapidly, the enterprises now find the traditional workflow management system under such rapid circumstances difficult to copy with changes in the market both promptly and flexibly. The inflexibility of traditional workflow model has cumbered the development of enterprises. Introducing SOA technology to current workflow management systems, we propose a service oriented workflow model to solve the problem mentioned above.Based on this framework, this paper also discusses how decentralized process enactment, and dynamic process adaptation can be achieved. It can improve flexibility, scalability, and interoperability and the proposed workflow management system can cooperate with other systems and enterprise applications more effectively.
