On the relationships among four timed process algebras. (English) Zbl 1066.68534

Summary: We contrast (the core of) four well-known process algebras specifically enriched for the specification and verification of timed systems. The aim of this comparison is twofold. On one hand it permits to gain confidence on how time and time passing are modelled in the four different timed process algebras. On the other hand, it establishes conditions under which mappings from a calculus to another can be provided which preserve (strong bisimulation-based) behavioural equivalence.
