The article is devoted to the task of condition analysis of control systems for distributed infrastructures based on technical diagnostics and reliability theory procedures and methods. The urgency of the problems to be solved is substantiated, a brief review of scientific publications in this field is carried out, and directions that require further research are analyzed. The concept of "distributed infrastructure", integrating the automation, control, communication and data transmission subsystems within the technological systems is introduced. The model of distributed infrastructure control system is designed, the main processes of its functioning are described. The analysis of elements models of control systems for distributed infrastructure at the component level and interconnection protocols is executed. The diagnostic object is selected, its properties and characteristics are analyzed. A generalized and detailed diagnostic models of the control systems elements are proposed, their mathematical description using the methods of graph theory is performed. An approach to the development of algorithms for estimating the condition of control systems elements is shown, an example is given, and the results of their practical implementation are shown. The method for calculating and analyzing operational and technical parameters of control systems elements based on methods of reliability theory is proposed. The influence of indicators of diagnosis and checking different stages on the operational and technical parameters of the control systems elements is estimated, an example of the use of the proposed method with using the software modeling tool is given. Conclusions on the results of this paper are made, recommendations on their practical application are offered.
