Automatic Concurrent Program Generation from Petri Nets

Automatic generation of code from Petri-Nets is an important topic. This paper presents a new approach to automatically translate Petri nets into concurrent program. In the proposed approach, place in Petri net is viewed as variable and transition as operating statement which change place marking according to enable and firing semantics. In order to conveniently translate Petri net to CC++ program code, sequence block and independent transition is defined and a graph called virtual Petri net is constructed. The translation rules of sequence structure, concurrent structure, select structure and loop structure of Petri nets are developed. According to these presented translation rules, an algorithm of concurrent program code generated automatically for Petri net was proposed. Finally, through case study, the effectiveness of the developed approach is illustrated.
