Description: There is a row of approaches in relation to the estimation of efficiency of functioning of structure of control the system. The main task of control the system is providing of achievement of purpose of activity of organization by the estimation of indexes of efficiency, exposures of inconsistency in criteria and forming of managing influences. Control the system must be up-diffused hierarchically and functionally, and its structure to answer functions and management tasks. For the estimation of indexes of efficiency of structure of control the system a simulation model is built, the proper software is developed, research and analysis of results is conducted.
Keywords: efficiency, simulation model, design, organizational model, functionality
