The combination of formal and informal elements allows for selective verification, an important requirement for practical use of formal refinement.

The case study is conducted in a top-down fashion, and we demonstrate that verification can be naturally conducted at the same time as, and combined with, the design of the system.

,Äquivalenzkalkül und orientierte Graphen,ituation a natural framework for implementation correctness requires a more general notion of refinement than that of [HHS87], a notion which involves the introduction of separate refinement relations for .’s various abstract components. An outline is given of a formal framework for proving implementation correctness that involves these notions.

Traditionally we have been most active in the world’s shipping industries where we have provided an independent “third party” service based on our own rules and standards for 230 years. During this century, however, this “third party” role has been increasingly extended in

This enrichment gives the calculus status as a general computational model. Its main character is what may be called the . paradigm, since it most directly represents the action and reaction among indep
