Abstract
The paper deals with the verification of reconfigurable real-time systems to be validated by using the Object Constraint Language (abbrev, OCL). A reconfiguration scenario is assumed to be any adaptation of the execution to the system environment according to user requirements. Nevertheless, since several behaviors can be redundant from an execution to another, the use of OCL is insufficient to specify the constraints to be satisfied by this kind of systems. We propose an extension of OCL, named Reconfigurable OCL, in order to optimize the specification and validation of constraints related to different execution scenarios of a flexible system. A metamodel of the new ROCL is proposed with formal syntax and semantics. This solution gains in term of the validation time and the quick expression of constraints. The paper's contribution is applied to a case study that we propose to show the originality of this new language.
