The article deals with the issues of integrated assessment of complex technical systems stability functioning in techno sphere and info sphere. It is shown that the concept of cyber stability, including its components such as cyber reliability, noise immunity and cyber survivability are insufficiently investigated and defined. The formal definition is given and the scale with various gradation of cyber survivability is entered. On the example of robotic systems in form of drones two variants of mathematical models of cyber survivability estimation are considered. The first variant is related to the description of drones functioning in the conditions of computer attacks without impact protection systems. The second variant reflects the functioning of drones under the conditions of impacts in the presence of adaptive combined cybernetic protection system. In both variants, two strategies are considered - with minimal and maximum intensity of effects on the drone. It is concluded that proposed in the paper approach enables to evaluate the integrated stability of complex technical systems in the techno sphere and info sphere at the same time.

Technical Systems

When designing complex organizational and technical systems, one of the main quality criteria is to meet the requirements for indicators characterizing the operational and technical level of the system. The task of substantiating these requirements has not been systematically approached. Requirements, most often, are presented empirically or using the apparatus of expert analysis. This is due to problems in the field of formalization of processes occurring in complex technical systems, difficulties arising in the construction of mathematical models and the development of criteria that allow optimizing information, technical, software, linguistic and other structures of ACS. The problem of substantiating the requirements should be solved using a systematic approach, and the whole set of properties, integral and partial indicators of the system should be taken into account. The study focuses on the approach to solving the problem of substantiating the requirements for reliability indicators of technical means of an organizational and technical system using the apparatus of continuous Markov processes. Time between failures and recovery time were used as reliability indicators. As a result, we found an analytical solution to the problem of substantiating the requirements for the reliability indicators of technical means and the characteristics of their performance, as well as the number of computer network workstations, necessary to meet the integral requirements for the ACS.

Structure Of Knowledge

The article analyzes a number of methods of knowledge formation using various graph models, including oriented, undirected graphs with the same type of edges and graphs with multiple and different types of edges. This article shows the possibilities of using graphs to represent a three-level structure of knowledge in the field of complex technical systems modeling. In such a model, at the first level, data is formed in the form of unrelated graph vertices, at the second level – information presented by a related undirected graph, and at the third level – knowledge in the form of a set of graph paths. The proposed interpretation of the structure of knowledge allows to create new opportunities for analytical study of knowledge and information, their properties and relationships.

Diagnostic Software

Authors explore issue of applicability of the methodology of building diagnostic software using network formal models in the functional testing of electronic equipment as part of complex technical systems. Using methods of system analysis allows to perform a decomposition of interdependent subsystems and to reveal basic acts of interaction between the control‑verification equipment and the object of diagnosis. Mathematical apparatus of Petri nets should be employed for the formalized description of such acts and determined the cause‑and‑effect relations in the diagnosed complex system`s processes. Network models properties studying (such as safety and accomplishment of the final positions) allows us to move to the test object`s algorithm`s developing. The article presents an approach of a formalized description for basic acts of interaction between the diagnosis system and the object.
