Functional specification of time sensitive communicating systems,n of the specification method to timed communicating functions is demonstrated. The relationship between nondeterminism and timed systems is investigated. Forms of reasoning are considered. The alternating bit protocol is used as a running example.

Abadi & Lamport and stark: Towards a proof theory for stuttering, dense domains and refinement mappe problems are solved satisfactorily in the work of Abadi & Lamport [AL88]. Syntactically, however, their solutions have no obvious prooftheoretic counterpart. By formulating Abadi & Lamport‘s concepts within Stark‘s formalism for dense Linear Time Temporal Logic [Sta88] a step in this direction is made.

Various simulations and refinements,r the formal development of communicating processes by integrating the event-based approach (such as CSP [3] and CCS [7]) with the state-based technique (such as Z [10] and VDM [4]). The methodology is illustrated by investigating various kinds of process refinement and their corresponding simulation rules.

On decomposing and refining specifications of distributed systems,rification conditions, using a notation with guarded assignment statements. We examine conditions under which the techniques are complete. One results is a variant of a completeness theorem due to Abadi and Lamport [AL88]. Simple examples are included to illustrate the techniques.
