A new approach to the analysis of Petri nets: parallel processes and predictability of scenarios

We suggest a new approach to the analysis of Petri nets. It consists of extracting pairs of independent (parallel) transitions, constructing the set of auxiliary objects of those pairs, and treating it on the basis of natural and obvious rules. This allows one to extract all possible scenarios in the behavior of Petri nets and to evaluate their probability-like characteristics in the case of several scenarios.
