A Simulation Methodology for Evaluating the Reliability, Availability and Performance of the Next European Torus

The operating targets of the Next European Torus (NET) vary over the planned physics and technology phases of operation, which will be cyclic and dynamic. Using the Dynamic Systems Simulation Language a model is described which mimics the cyclic behaviour of the NET over the technology phase together with its dynamic behaviour. The simulation model represents a methodology that can be used to evaluate the reliability, availability and performance of the NET. A number of case studies are presented to demonstrate the underlying philosophy of the approach.
