We propose a formal and mechanized framework which consists in verifying proof rules of the B method, which cannot be automatically proved by the elementary prover of Atelier B and using an external automated theorem prover called Zenon. This framework contains in particular a set of tools, named BCARe and developed by Siemens IC-MOL, which relies on a deep(More)
We propose a method that allows us to develop tableaux modulo theories using the principles of superdeduction, among which the theory is used to enrich the deduction system with new deduction rules. This method is presented in the framework of the Zenon automated theorem prover, and is applied to the set theory of the B method. This allows us to provide(More)
Telecommunication operators provide services and enable customers to compose their own packages of services. While designing a service-oriented system, deciding whether a service interaction is desired or harmful is a subjective choice which depends on the requirements expressed by the user with respect to the service integration. In this paper, we define(More)
Telecommunication systems involve many optional features which cannot be combined according to an obvious definition because they can interact together in an unpredictable way. In order to find the best way to combine features, a major difficulty is to foresee or to discover when a feature can disrupt an another one. Once such an interaction has been(More)
