The complex "input-output" system with a given structure is considered in the paper. For each element of the system the class of submodels is given. For each class the local criterion and for the whole system the global criterion are determined. The problem consits in finding such submodels from the given classes which minimize the global criterion, i.e. to find such submodels to obtain the globally optima} model for the whole system after composing the submodels according to the given structure. The generał problem of the global optimal model is formulated and fome special problems for the special cases concerning the form of the structure are considered. The second part of the paper is concerned with the global identification problem for the complex system. The generał approach to the solution for cascade structure using dynamical programming method is given and the algorithms of global identification for static and dynamical models and the cascade structure are presented.
