[ From the performance mailing list. --DL ] I appreciate it if you could broadcast about this tech. report to all the members of this group. Petri nets and Various extended net types: A comparative study Gurdeep S. Hura and Farhad S. Etessami Absract Petri nets and related graph models have been recognized as a useful and effective modeling tool for the representation,analysis and design of concurrent and asynchronous systems.Due to inherent properties of Petri nets to model flow of information(data and control),they have been extensively modified to meet the requirements of different applications.Extensions of Petri nets have in most cases resulted into increasing the modeling power to that of Turing machine, and thus decreasing the decision power. In this technical report an endeavour is made to discuss various extensions of Petri nets,make an analytical comparison between them,and show a hierarchy of their modeling capabilities. Further,an attempt will be made to come up with some suggestions as to the general area where future research should be directed.
