Abstract
Mean Value Calculus (MVC)[1] is a real-time logic which can be used to specify and verify real-time systems[2]. As a conservative extension of Duration Calculus (DC)[3], MVC increases the expressive power but keeps the properties of DC. In this paper we present decidability results of MVC. An interesting result is that propositional MVC with chop star operator is still decidable, which develops the results of [4] and [5].
