A Temporal Concurrent Constraint Programming Calculus

Abstract The tcc model is a formalism for reactive concurrent constraint programming. In this paper we propose a model of temporal concurrent constraint programming which adds to tcc the capability of modeling asynchronous and non-deterministic timed behavior. We call this tcc extension the ntcc calculus. The expressiveness of ntcc is illustrated by modeling cells, asynchronous bounded broadcasting and timed systems such as RCX controllers. We present a denotational semantics for the strongest-postcondition of ntcc processes and, based on this semantics, we develop a proof system for linear temporal properties of these processes.
