Proxy Possible Flow Semantics for Enterprise Formulae and Artefact Possible Lives Models

An operational semantics is defined for enterprise formulae (EF) -a language for specifying enterprise models- and artefact possible lives models (APLM) -a language for specifying product (life cycle) models-. The semantics is explained by means of the MiViPoRo framework. The conceptual background for the paper is drawn from early definitions of syntax and semantics, and from work on the operational semantics of programming languages. The operational semantics of EF and APLM involves the possible flows of proxies in a network of cells.
