Confidence Component Model for Separating Function and Capability

To provide credible services and facilitate the development of applications for the distributed real-time embedded system (DRES), a credible service component model, QUOCCM, is proposed. By QUOCCM, a DRES application is separated into two parts: function realization and performance guarantee. The latter is encapsulated into some components to provide common services for the former. Specially, QUOCCM can provide an adaptive service support about application performance running in the dynamic environment. Finally, a flight control system in DRES has been used to confirm the feasibility and flexibility of the model.
