| Краткое описание: | Today, cyber-physical systems (CPS) are increasingly used in everyday life. However, they are subject to a wide range of cyberattacks. A comprehensive review of countermeasures is important because countermeasures may not be limited to an attack. Unmanned aerial vehicles (UAVs) are one of the types of cyber-physical systems. In this paper, cyber-physical systems are the object of study, and unmanned aerial vehicles are the subject of study. The purpose of the work is to develop a methodology (algorithm of actions) to improve the fault tolerance of CPS in emergency situations. To develop the methodology, an analysis of the CPS architecture was carried out, existing methods for assessing the risks of CPS were evaluated, an algorithm for calculating the risk of risks affecting CPS was compiled, and it was also tested on real CPS. As a result of the study, shortcomings in similar risk assessment methods were identified and eliminated in the developed algorithm. The technique allows to calculate the hazard coefficient of system failure, the probability of a negative event for the system. The novelty of the work lies in the correlation of the types of external destructive influences on the CPS, its cyber-physical parameters, structural and functional characteristics, and the identification of the consequences for the CPS. |
