Abstract: This paper is devoted to probability-statistical analysis of Jackson opened and closed networks. A prob- lem of an estimation of product limit distributions parameters using load coefficients of network nodes is solved. Cooperative effects in aggregated opened and closed networks are investigated and optimization procedures of their limit deterministic characteristics are constructed. Formulas of a calculation of limit distributions in superpositions of networks (nodes are replaced by opened networks) are obtained.
