We are interested in verifying dynamic properties of finite state reactive systems under fairness assumptions by model checking. The systems we want to verify are specified through a top-down refinement process.In order to deal with the state explosion problem, we have proposed in previous works to partition the reachability graph and to perform the(More)
We use the formal method B for specifying interfaces of software components. Each component interface is equipped with a suitable data model defining all types occurring in the signature of interface operations. Moreover, pre-and postconditions have to be given for all interface operations. The interoperability between two components is proved by using a(More)
One of the principal goal of Component-Based Software Engineering (CBSE) is to allow the reuse of components in diverse situations without affecting their codes. To reach this goal, it is necessary to propose approaches to adapt a component with its environment when behavioural mismatches occur during their interactions. In this paper, we present a formal(More)
Component interoperability is one of the essential issues in the component based development, since it allows the composition of reusable heterogenous components developed by different people. In this paper, we propose an approach to formally verify component interoperability at signature, semantics, and protocol levels. It is based on the use of the B(More)
