- Abstract
We present a functional central limit theorem which quantifies, as a stochastic process, the difference between a PEPA model's underlying CTMC and its fluid approximation. We generalise existing theory to handle the case of non-smooth rate functions, which is an issue particular to modelling problems in computer science. We verify the weak convergence empirically and suggest future avenues for deducing more analytic approximations from it.
