A good model-reduction method gives us: 1. bound(r) – To help us choose a suitable approximation order r; and 2. a reduced-order model (f r,g r) alt. (A r,B r,C r,D r). Such methods exist for some classes of models (typically linear). Many heuristics fail to provide bound(r).

Overview. Many modern mathematical models of real-life processes pose challenges when used in numerical simulations, due to complexity and large size (dimension). Model order reduction aims to lower the computational complexity of such problems, for example, in simulations of large-scale dynamical systems and control a reduction of the model's associated state space.
