Parallel software engineering with PARSE
Ian Gorton, Innes Jelly, Jeff Gray · 2002
The aims of the PARSE methodology are described, and the process graph design notation is summarised. Process graphs are a new graphical notation for describing systems comprising a collection of parallel processes in a language- and architecture-independent fashion. Further, process graph designs can be mechanically transformed into Petri nets to give a more detailed, executable design specification. Some simple process graphs and their corresponding Petri nets are described in order to demonstrate this transformation process. A more extensive example then illustrates the initial stages of the design process in practice.>
