I have just started looking at Petri Nets for possible realtime software system performance modeling. A cursory review of what has happened in this area of research, I have found the ordinary Petri Nets and its time extension could be quite useful to my work. Since I am very new to this part of world, I wonder if anybody in this group knows the current state of Petri Net application to industry. I have seen and heard some commercially available tools like ADAS, a UNIX tool called "petri" written by Ira Forman in MCC, and a colored Petri Net analysis tool from Meta Software. The implementation of these products vary quite much. I wonder, for industrial realtime software application, at what level I would need for such tool? The mentioned commercial products are quite expensive to my project. I wonder if there is a public domain package available? My software system will extensively use shared-resources and priority of different execution tasks. The shared-resources have many good models built in the past, but I haven't seen many priority system models. Any help will be greatly appreciated. Frank Wang @ John Fluke Mfg.
