Abstract process definitions in CSP- A case study
This paper presents a CSP specification of a case study for an environment control system for a building. The modification of CSP process definitions to incorporate reuse via inheritance is the main issue presented in this work. Incremental and behaviour modification are two techniques that are presented in order to model object-orientated inheritance. In its current form CSP does not provide many facilities for reusing existing components of a specification. This paper presents an addition to the language of CSP by parameterising initial actions and subsequent behaviour in the signature of a process which then permits behaviour to be modified in situ as well as by the extension of action choice.
