Integrated Estimation of a Cyber-Physical System’s Sustainability

Currently, in conditions of Industry 4.0, the use of cyber-physical systems in various fields is becoming widespread. This article is devoted to the problem of estimating CPS sustainability in the context of modern challenges faced by decision makers and IT developers in order to ensure effective proactive business process management using this innovative technology. The purpose of the research is to propose and substantiate a methodology for estimating CPS sustainability to ensure the reliability and strength of its elements, their interrelationships and interaction, as well as the effective functioning and development of this system in conditions of high dynamism and uncertainty of the external environment. In this study, we used methods of integral evaluation, synthesis, expert assessments, dynamic analysis, and systematic approach, and coined the term ‘CPS sustainability’. Our study showed that negative risks, external and internal threats may have a significant adverse impact on CPS sustainability. The reliability of this system should be evaluated on the basis of integrated indicators. The key indicators, reflecting the reliability of maintaining the properties of the CPS in a normal state of its function and further development, were identified. We propose a methodology for estimating CPS sustainability. In general, the presented results form the basis for improving CPS management to increase the effectiveness and efficiency of its functioning and development.

DIFFERENTIAL-GAME MODEL OF INFORMATION PROTECTION FOR COMPUTER SYSTEMS OF TRANSPORT INFRASTRUCTURE

The article considers the reliability and protection of information of computer systems of transport infrastructure and describes the synthesis and analysis of differential game models and methods of modeling cyberattack processes on the server of computer information and diagnostic systems of the railway power supply distance. A unified differential-game model of the cyberattack process on the multi-task server of the information-diagnostic computer system of the lower level of the railway has been developed, which allows to obtain optimal strategies for information protection in cyberattacks. The results of modeling the cyberattack process are presented, to assess the integrated indicators of server security, using the optimal strategies for each of the functions. The appearance of the unified model of the computer information system is shown, and the graphs of the transient processes of the probability of the server being in a protected state and the probability of server failure for any of the functionalities are given.

Modernization Processes Development in the Implementation of Intellectual Capital in a Crisis

A model of industrial enterprise's market orientation on the basis of marketing strategy choice

Subject. The article investigates the process of market orientation of enterprise functioning based on a marketing strategy. Objectives. We focus on building a model of market orientation of enterprise functioning, enabling to choose a development strategy and increase production efficiency. Methods. The study rests on developments, concepts and hypotheses that are justified and reflected in the works on the problems of economic theory, economic growth, and development. Results. We present a model of market orientation of enterprise functioning, which is based on a marketing strategy. Conclusions. The proposed mechanism for assessing a market orientation model at the enterprise enables to create a universal criterion that takes into account both financial and non-financial indicators of evaluating a marketing strategy, namely, an integrated indicator of customer value satisfaction. A special feature of the model is the ability to compare integrated indicators of customer value satisfaction for each developed marketing strategy at the enterprise. As a result of such a comparison, it is possible to choose the most effective strategy for the analyzed enterprise.

ESTIMATION OF FINANCIAL RELIABILITY OF THE INSURANCE COMPANY

The article considers the assessment of the financial reliability of the insurance organization. It is shown that the financial reliability of the insurance organization is a comprehensive indicator and depends on a number of factors. The classification of financial reliability factors on the basis of the possibility of management and depending on direct and indirect influence is considered. Approaches to assessing the financial reliability of an insurance organization, which use both single indicators and scorecards, are considered, their advantages and disadvantages are determined. It is shown that the advantage of using integrated indicators is the ease of use and the ability to take into account various factors. To assess the financial reliability of the insurance organization, the use of the Harrington model is recommended and a list of model factors is defined.
