    The Algebra of Communicating Shared Resources, ACSR, is a timed process algebra that is based on the premise that the timed behavior of a real-time system is affected not only by the time its components take to execute and synchronize, but also by delays introduced due to the scheduling of actions that compete for shared resources.

    The ACSR computation model is based on the view that the components of a real-time system execute synchronously time and resource consuming actions and communicate through instantaneous events asynchronously, except when two components synchronize through matching events. To be able to specify real-time systems accurately, ACSR supports static priorities that can be used to arbitrate between actions competing for shared resources and between events that are ready for synchronization. ACSR also offers different notions of equivalence that can be used to verify that two specifications behave the same
