چکیده

The interactive theorem prover PVS is used to formalize the user needs of the Light Control system. First the system is modeled at a high level of abstraction, in terms of properties the user can observe. After resolving ambiguities and con icts, a re nement is de ned, using dimmable light actuators. Correctness of the re nement has been proved in PVS, under the assumption that there are no internal delays. Next these internal delays are taken into account, leading to a new notion of delay-re nement which allows abstraction from delays such that systems with delays can be seen as an approximation of an undelayed speci cation.
