This paper presents a class of Stochastic Petri Nets with concurrent transition firings. It is assumed that transitions occur in steps and for every step each enabled transition decides probabilistically whether it wants to participate in the step or not. Among the transitions which want to participate in a step,...

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...

In the last decades, a number of stochastic enrichments of process algebras was constructed to specify stochastic processes within the well-developed framework of algebraic calculi. In [26], a continuous time stochastic extension of finite Petri box calculus (PBC) was proposed and called sPBC. The algebra sPBC has...
