Simulation has become an indispensable support in the design process. This is particularly evident in the design of complex, multi-domain and multi-physics systems, where, though, the setting up of the system model and the size of the problem are unresolved challenges. In previous works we proposed a method to describe the different levels of detail of the models of components, given a design objective. This method is based on stochastic analysis and wavelet analysis, and the results are lumped in indices that allow for the classification of available models of each component to be used for level selection in system models composed of component models. In this paper we extend the set of design objectives proposing new indices. A case study is proposed to demonstrate the concept.
