Abstract

The problem of computer linkage of different mathematical models into a whole system in order to investigate their joint behavior with more common criteria and constraints seems to receive more and more consideration. 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 report an approach is described which permits the investigation of a set of linked subsystems without explicitly building any integrated model.

This report represents a description of a particular approach which might be referred to as "distributed modeling." It deals with conceptual systems in general, which might be used to model concrete systems at any level. The use of the method is illustrated by the practical application of the development of a system of regional models. 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.
