Abstract. Alternating transition systems are a general model for composite systems
which allow the study of collaborative as well as adversarial relationships between
individual system components. Unlike in labeled transition systems, where each tran­
sition corresponds to a possible step of the system (which may involve some or all
components), in alternating transition systems, each transition corresponds to a possible
move in a game between the components. In this paper, we study refinement relations
between alternating transition systems, such as ``Does the implementation refine the set
A of specification components without constraining the components not in A?'' In par­
ticular, we generalize the definitions of the simulation and trace containment preorders
