In this paper we examine an important property of correct system design that is called non-Zenoness or time progress. We present a method that allows to check non-Zenoness on a restricted subclass of real-time processes. The processes that we examine are constructed by nondeterministic sum and parallel composition with synchronization. The method is based on the construction of a finite representation of the potentially infinite state space of a process, that preserves time progress.
