During the design of automated control systems, the minimum possible level of risks of uncontrolled interference in the operation of these systems is required, as well as minimizing the negative consequences of such intervention in the process of its operation. In connection with this, on the basis of the system theory of confl ict management and the matrix approach to describing the structure of complex organizational systems, the task of diagnosing the operability of executive devices to control the identifi cation of internal confl icts between them is solved. In this paper, an algorithm is proposed that makes it possible to identify confl icts in the functioning of systems of this class both at the stage of their development and during operation. In addition, the paper proposes a complex of dynamic models for the processes of making diagnostic decisions about the operability of the components of executive devices of an automated control system described by the Petri-Markov network, which allows us to propose a method for making diagnostic decisions, to determine the diagnostic functionality, to determine the performance level of actuators and to obtain a diagnostic Conclusion, as well as assess the risks of working capacity of executive roystv, taking into account risk factors, health of components and actuators of the list of faults associated automated control system. Software or hardware implementation of this algorithm allows creating a universal means of diagnosing and controlling the integrity of an automated control system.
Keywords: automated control system; executive device; diagnostics; confl ict; control process; resource.
