Abstract

Many works on analyzing the behavior of complex systems are based on building large-scale integrated models and sequentials using decomposition and aggregation procedures. In this paper an approach is described which permits to investigate a set of linked subsystems without explicitly building any integrated model.

This approach based on the 'smooth' version of the Sequential Unconstrained Minimization Techniques (SUMT) can be considered from a mathematical point of view as a realization of the 'general decomposition scheme' (Orchard-Hays 1968).

Section 1 describes the statement of the problem; Section 2 gives a general description of the idea of the SUMT; Section 3 contains the conditions of applicability of the approach; and in Section 4 we give a short description of the practical realization and computer testing of this method for a case of linking two submodels of a health care system.
