Traditional performance analysis has always suffered from the state-space explosion problem. Recent research has indicated that state-spaces can be approximated by continuous variables allowing the exploration of the performance properties of huge systems of industrial scale. I work on developing mathematical models based on ordinary and stochastic differential equations and showing formally how these relate to the original discrete state model.
