Sažetak

General chemical engineering modelling principles are valuable tools to represent both stationary and dynamic characteristics of complex cell processes. Elaboration of reduced (lumped) dynamic models uses all types of information ‘translated’ from the ‘language’ of molecular biology to that of mechanistical chemistry, by preserving cell structural hierarchy and component functions. A combination of non-/conventional estimation methods reported significant model quality improvements by accounting for qualitative/ quantitative data and global properties of the living system. Derivation of a satisfactory
model is closely related to the ability of selecting the suitable lumping rules, key-parameters, and influential terms that better realize a trade-off between model simplicity and its predictive quality. Several examples, on the modular modelling of protein synthesis
regulation, genetic regulatory networks, and on the successive drug-ligand release in human plasma from a complex multivalent support, illustrate the advantages but also the over-simplifications introduced by various lumping rules.
