Abstract: This paper presents PROTOB, an object oriented language and methodology based on PROT nets, and the CASE (computer-aided software engineering) environment that supports it. PROT nets integrate extended dataflows and Petri nets into an object oriented formalism. The CASE environment consists of several tools supporting specification, modelling and prototyping activities using the PROTOB language. As its major application area it addresses distributed systems, such as communication protocols and manufacturing control systems. A model of a flexible manufacturing system and its production control software are analysed as a case study.
Keywords: PROTOB; object oriented methodology; discrete event dynamic system; PROT net; computer-aided software engineering; communication protocol; flexible manufacturing system (control).
