Description	Proceedings 22nd International Symposium on Mathematical Foundations of Computer Science (MFCS'97 . Action refinement in process algebras has been widely studied in the last few years as a means to support top-down design of systems. A specific notion of refinement arises when a dependency relation on the actions (in the Mazurkiewicz sense) is used to control the inheritance of orderings from the abstract level. In this paper we present a rather simple operational semantics for dependency-based action refinement. We show the consistency of the operational with a (previously published) denotational semantics. We moreover show that bisimulation is a congruence for dependency-based refinement. Finally, we give an illustrative example. 1 Introduction Action refinement in process algebras [1, 2, 18, 11, 8, 9] has been proposed to support hierarchical design of reactive systems. Starting with an abstract specification, step-by-step more concrete specifications are constructed by refining actions into concrete processes. Thus the complexity of the design process is reduced and furthermo...
