Abstract: Stochastic extensions to Petri nets are capable of representing the kind of of complex behavior exhibited by distributed computer architectures. However, traditional methods of system evaluation with respect to various measures of performance, dependability, and performability quickly become intractable for large systems. This problem is addressed in the context of stochastic activity networks (SANs) by developing base model construction methods that account for symmetries in SAN structure. The authors find that such a technique can yield dramatic reductions in state-space size while preserving stochastic properties required for practical means of solution.

Keywords: networks. stochastic activity network; performance; reduction (by) symmetry.
