ABSTRACT
The aim of the present work is to develop the methodology of the analysis of multiple-factor influence on the system in the presence of the correlation between the factors. As an example the analysis of the influence of a complex of interrelated risk factors on the health of population (preschool age children) is held. Multiple-factor analysis is based on the successive consideration of one-, two- and multiple-factor influences. In the presence of more than two factors to find a complex of factors having the most influential effect on the system, it is suggested to use the idea of hierarchical classification within the framework of which there has been developed and tested an original algorithm. There have been suggested certain methods of the search for factors that allow to diminish the negative influence on the health of population caused by the pollution of the environment.

KEY WORDS: multiple-factor response, correlated factors, the finding of the main factors, the hierarchical classification, the health of population, the compensation of the negative influence of the risk factors.
