Abstract: Lazar and Robertazzi (cf Petri Net Newsletter 28, p. 35) described a class of stochastic Petri networks with product form solution for the equilibrium state probabilities. This work extends this class to the case where service times consist of a series of distinct exponential stages.
Keywords: service stage; net protocol; product form solution; equilibrium state probability; distinct exponential stage.
