Information systems function under the influence of external and internal destabilizing factors. Under negative influence, system modules may fail. However, the systems must function offline for a specified time. Such a condition of functioning can be fulfilled by ensuring the property of functional stability. The property of functional stability was introduced due to the observation of the behavior of biological systems, organisms with the inherent property to fulfill given goals with physical damage due to biological redundancy: sets of sense organs, physiological analyzers, nerve fibers, the configuration of the brain as a control and information processing system, as well as symmetry body The main feature of functionally stable systems is their ability to degrade at the structural level until the system completely fails, that is, to exclude defective elements from the structure, to rebuild the structure, to adjust the system parameters. adapt to new operating conditions. The main means of ensuring functional stability is the introduction of redundancy (structural, software, time, etc.) during their design. The paper analyzes the existing scientifically based approaches to increasing the efficiency of complex technical systems, which include an intelligent automated control system. A technique for determining the features and indicators of the functional stability of the special purpose network structure, which provides communication between the UAV group and the operator, is proposed. Quantitative methods for assessing functional stability based on the above indicators are proposed. On the basis of these assessments, recommendations can be made on the construction of the structure or reasonable requirements for the structure of the wireless sensor network that will be designed and operated can be formulated. the main feature of functionally stable systems. It has been established that this is their ability to degrade at the structural level until the complete failure of the system, that is, to exclude defective elements from the structure, rebuild the structure, and adjust the system parameters to adapt to new operating conditions. It has been proven that the main means of ensuring functional stability is the introduction of excesses into their construction: structural, program, time, etc.
