Workflow technology is a key technology to improve business process efficiency and productivity. It can monitor, control and coordinate the business processes and programs and can track the flow of work and information as well as the utility and inputs of resource in advance. Through workflow systems have a significant impact on organizations in the past decade, how to rapidly and cost-effectively satisfy the various dynamic demands of the market adapt to an unpredictable business environment and increasing rates of new production methods are the major challenges for enterprises. A service-based dynamically reconﬁgurable system framework was proposed in the paper. In the framework, a service center represents an intelligent service broker that offers a self-managed and integrated service to respond to the requests from the workflow adaptively. A workﬂow engine in this framework coordinates these service agents to implement particular business functions. The structure of the service agent, including its plan model, the relevant reconﬁguration method and a service optimization mechanism, were discussed in the paper. A case study and an implementation were also presented.
