The main disadvantages of the existing methods of managing the current state of technical systems are revealed. A non-standard approach is proposed for managing the functionality of the system in emergency situations.
The character of the dynamics of the recovery processes of the technical system is determined as its state approaches the emergency one on the basis of the recommendations of the theory of self-organized criticality (SOC).
The physical criteria for assessing the current state of the technical system are revealed. The rationale for using the physical indicator of the functional destabilization of the system is given. The signs of the pre-emergency state of the technical system are considered.
A grapho-analytical model for the development of an emergency situation has been developed. The fact of the inevitable increase in the entropy of the system upon its transition to an emergency state is established. Structuring of the system development process in an emergency situation is carried out in three stages.
The methodology for estimating the pre-emergency state of complex open systems is presented. The advantages of the proposed approach to managing the state of technical systems in comparison with traditional ones are established.
