Abstract

It is necessary to estimate system performance to ensure cost-effective system design. In addition, discrepancies between estimated performance and system performance must be established as a guidelines for the use of the simulator in advanced. We have developed and evaluated a PACS system simulator, `UNSUI/P'. UNSUI/P is based on discrete event simulator, `UNSUI', developed by Toshiba Research and Development Center. UNSUI/P was evaluated by simulating a number of PACS and comparing the results against actual system performance. Evaluations for a single component and for the entire system were carried out. Discrepancies between simulation results and actual system performance ranged from 30% to 50% for the response time in the first evaluation. In the second evaluation, simulation of the delay time for image transfer from a modality to a viewing workstation was performed and discrepancies in the delay time appear to be about 15% to 40%.
