Model Model Domain
A Modal Model is a finite set of Actors (other models), all having
the same set of inputs and outputs, associated each with states in a
finite state machine. For any given state, the associated Actor is
known as a Refinement of this state. During each firing of this Modal
Model the refinements associated with the current state in the state
machine fires. Subsequently, the evaluation of guards in the state
machine determines which state, if any, to transition to, thereby
determining the next refinement to fire.
