Service Component Architecture (SCA) is a set of specifications which describe a model for building applications and systems using a Service-Oriented Architecture (SOA). However, SCA in its current form does not represent any formal definition. In addition, there is a growing interest for verification techniques which help to prevent SCA composition specification failure. In this context, we intend to propose an Event-B based approach so as to configure the SCA composition dynamically. We focus, particularly, on the correctional dynamic such as substituting faulty services and components. The consistency and the validity of the obtained model have been proved by the Event-B dedicated tools
