Hierarchy of models in mathematical biology and numerically-analytical methods of its investigation (review)

The problem of intermodel relations in mathematical biology is considered. Certain mechanisms of prime models generation from complicated ones are briefly reviewed (the asymptotic decomposition, self-organization, reduction principle and others). The construction of complicated model from prescribed prime models and development of hierarchy of models are also considered. The notions of minimal, maximal and primary model are treated. The key role of analytical methods of investigation is emphasized.
