Abstract
The refinement calculus of Back, Gardiner and Morgan can be extended to fair nondeterministic programs. The rules of refinement are based on conditions over actions composing programs under refinement. The document explores several transformations of programs from transformations of actions. Applications to the refinement in UNITY-like frameworks show that the refinement preserves invariance properties and eventuality properties under the justice (resp. fairness) assumption. Moreover, the granularity of programs may be modified according to these rules of refinement.
