The structural and functional diagrams of the thermoanemometric type sensor for measuring the mono- and biphasic (liquid + gas) medium by the pulsating nature of the flow are presented. The temperature distribution in the sensor environment is considered and the sensing elements are not in contact with the inner surface of the sensor body.
A comparative analysis of existing approaches to Cyber-Physical Systems simulation has been conducted. The intrinsic peculiarities of Cyber-Physical Systems have been reasoned and generalized. Thelimitations of available simulation tools have been pointed out. The approach to Cyber-Physical Systems design solutions checking on the basis of timed automata, UPPAAL integrated tool environment and Temporal Logic of Actions usage has been proposed.
The article presents the approach to the formation of effective management teams, taking into account the complex review of tasks that appear in front of the organization. The development of the modern economy marked the structural changes in which knowledge became the main driving force, and therefore the requirements for organizing managerial labour increased significantly. The path of scientific search for methods of building rational organizational structures lies in the plan of studying the human factor in the field of managerial decision making.
The article presents a simulation model and described appropriate software, to simulate the environment in an emergency situation (accidents on chemically hazardous objects) or free observation (no pre-defined procedures). Collection and processing of information made using a wireless sensor network.
This article describes the features of classification methods and technologies, analytics Big data. Described group of methods and technologies, analytics Big data that are graded according to the functional relationships and formal model of information technology. The problem of the definition of ontology concepts analytics Big data.
The system aspects of optimality problem within the framework of the structure of decision-making process, connecting it with DM models and tasks, theoretical and practical aspects of optimal solution peculiarity were analyzed. The analysis entropic specification and their impact on the optimal level of practical decisions was made. The DM methods specifications in context of optimal decisions-making were compared, the consumption of partitioning and threshold method, as one of the most flexible for decision-making in different conditions were justified.
Some particular aspects of modeling method in scientific research have been outlined in the article. Philosophic maxims on which the model concept is based were suggested. The generalized model definition, its characteristics and typology were represented in the article
In this article optimal reduction models are presented. Peculiarities of their use in the process of decomposition tasks and complex system modelling are described.The influence of tht problem model on the designing result is analysed.
This article is devoted to development of model, based on Petri nets, which corresponds planning stage of RTS automatic design. The model was developed according to the algorithm of the planning stage, which is the basic one in five-level representation of the robotization project estimation process, and enables to explore the dynamics of the process and the reliability of the corresponding component of the RTS design system, also providing the possibility of additional RTS correction in a broader functional and constructive spectrum.
A conception of multilevel complex security system (CSS) of cyber-physical systems (CPS) was developed; dimensional model of information-technology state (ITS) was proposed; informational model of CSS cyber-physical system “iPhone – Wi-Fi, Bluetooth – sensors” was created; software of symmetric block data encryption of “Kalyna” algorithm was realized.
