We study property preserving transformations for reactive systems. A key idea is the use of ϱ-simulations which are simulations parametrized by a relation ϱ, relating the domains of two systems. We particularly address the problem of property preserving abstractions of composed programs. For a very general notion of parallel composition, we give the conditions under which simulation is a precongruence for parallel composition and we study which kind of global properties are preserved by these abstractions.
