In this paper, we deal with event-oriented models of concurrent processes which are generalizations of the well-studied model of prime event structures. In particular, we translate flow event structures into structures for resolvable conflict (the most expressive event-oriented model) and back, define two structurally different methods of generating transition systems...

Stochastic Petri nets (SPNs) is a well-known model for quantitative analysis. We consider the class called DTWSPNs that is a modification of discrete time SPNs (DTSPNs) by transition labeling and weights. Transitions of DTWSPNs are labeled by actions that represent elementary activities and can be visible or invisible for an...
