VV&A and confidence assessment of a complex giant system simulation model

It is difficult or even impossible for a pure mathematical model to represent a complex giant system because of the complexity, activity, uncertainty in such a system. The meta-synthesis methodology and the generalized modelling method are used to model a complex giant system. This paper has an in-depth study on the confidence assessment of a complex giant system simulation model that is built based on the meta-synthesis methodology and the generalized modelling method. A new definition of VV&A for complex system is given, on which is based a -step reference model and proposed for VV&A purpose. Furthermore, the principle andmethod of intelligent boundary interval intermediate assessment is proposed for the harmonization of modelling and model-validation.
