Abstract
We define a stochastic Petri net (SPN) semantics for stochastic process algebras (SPAs), a recently introduced formalism that offers a novel approach for performance modeling. The proposed semantics is evaluated in terms of three criteria: concurrency and retrievability, as defined by Olderog (1987, 1991) for untimed net semantics, and Markov equivalence for the stochastic aspects.
