The authors investigate the use of stochastic activity networks (SANs) and reduced base model construction techniques in evaluating picture archiving and communication systems (PACSs). Construction and solution of the models is done using UltraSAN, a graphically oriented software tool for model specification, analysis, and simulation. The method is illustrated via the evaluation of a realistically sized PACS for a typical US hospital of 300-400 beds, and the derivation of system response times and component utilizations. The approach is modular, in the sense that SAN models of individual PACS components can be reused when investigating alternative system configurations.
