A Tandem model approach. (a) In general, a model represents a subset of the network (Model A) within an entire network (Model U) (Left). In this case, what is happening in practice is to implicitly consider Model A is interfacing Model which is a black box of the rest of the network. With proper parameter tuning and value range restrictions, the model can provide reasonably accurate prediction of behaviors of the subset of the network. (b) Three models represent overlapping part of the network, and validated for their accuracy. This implies that these models are tuned for their counter-part black box. Within predefined range of values, a tandem application of three models is expected to deliver qualitatively useful predictions on behaviors of the network.
