Abstract:

It is shown that the behavior of generalized free-choice Petri nets with exponentially distributed firing times can be represented by probabilistic state graphs. For bounded Petri nets the corresponding state graphs are finite, stationary descriptions can thus be obtained by standard techniques used for analysis of continuous-time finite-state Markov chains. An immediate application of such a model is performance analysis of concurrent systems, and in particular queueing systems with exponentially distributed interarrival and service times. Places of Petri nets correspond to systems queues, transitions to servers, and bulk arrivals or services are conveniently modelled by generalized (multiple) arcs. Simple models of interactive computer systems are used as an illustration of performance evaluation.
