Introducing a priority operator to CCS

Juanito Camilleri

January 1989, 19 pages

DOI: 10.48456/tr-157


In this paper we augment the syntax of CCS by introducing a priority operator. We present a syntax directed operational semantics of the language as a labelled transition system. A new equivalence relation which is based on Milner’s strong observational equivalence [11] is defined and proved to be a congruence. We also give some examples which illustrate the use of the operator and emphasise the novelty of the approach used to introduce the notion prior to process algebras.
