In this paper, a dynamically customizable framework for supporting the autonomy of components is introduced. To implement autonomous components, the framework adopts an approach to repacking existing components. By combining Agent technology into components, the framework can customize behavior rules and plans for components to enable components to adjust their behaviors according to the states of the environment. By integrating a rule-engine that can interpret and execute declarative rules, the framework supports the autonomous behaviors of components without recoding and re-deploying of components.
