On the basis of the analysis of functional potentialities of modern information systems the applicability of multidimensional combined information structures is substantiated for the formation of the information support of technological pre-production automation systems of engineering production. There is developed a simulator of data for the formalized solution of the problem of elementary technological route formation for surface processing in case of quality complex indices application defined by product operation properties.

Concept Of Information

This paper studies information structures in a fuzzy β-covering information system. We introduce the concepts of a fuzzy β-covering information system and homomorphism between them, and investigate related properties. The concept of information structure of a fuzzy β-covering information system is given. We discuss the relationships between information structures from the view of dependence and separation. Then granularity measures for a fuzzy β-covering information system are studied. Finally, we discuss invariance of fuzzy β-covering information systems under homomorphism and illustrate its application on data compression.

Blackwell's Theorem

In a decision problem with uncertainty a decision maker receives partial information about the actual state via an information structure. After receiving a signal, he is allowed to withdraw and gets zero profit. We say that one structure is better than another when a withdrawal option exists if it may never happen that one structure guarantees a positive profit while the other structure guarantees only zero profit. This order between information structures is characterized in terms that are different from those used by Blackwell's comparison of experiments. We also treat the case of a malevolent nature that chooses a state in an adverse manner. It turns out that Blackwell's classical characterization also holds in this case.

The purpose – The purpose of the article was an attempt to assess the significance of two spheres connected with the functioning of DMOs, i.e. internet marketing and the development of modern technologies and information systems. Design – The study covers theoretical issues connected with the essence of destination management organizations as the basic organizational structures in the tourism sector, and with the significance of the Internet and modern information technologies in the activities of these organizations. The second part of the study covers the empirical issues of the problem analyzed. Approach and methodology – Apart from theoretical deliberations, it provides the review of previous research. Moreover, the results of the author’s research were used with the aid of the diagnostic survey technique. The results from 53 DMOs that represent 19 European states were obtained. Findings – The quantity of expenditures on information technologies was defined in the structure of the total expenditures on the part of DMOs. The average value for all the organizations under analysis was 10.9%. Owing to the application of the point grading method (Likert scale), it was demonstrated that internet marketing and the development of modern technologies and information systems are becoming increasingly more important areas of the activities. Originality of the research – The originality is evident in the insights it provides about use of modern information technologies and the Internet in the activities of DMO. The empirical deliberations presented in this article should become an important point of reference for many DMOs and should emphasize the growing significance of information technologies.

Subject. The article addresses a simulation in the structured query language (SQL) for the Bloomberg information base, the scientifically grounded tools for measuring emotions in markets in the face of financial and pandemic crisis and market imbalances, in addition to classic financial indicators, the creation of analytical tools based on state-of-the-art software tools that integrate the latest advances in behavioral finance and in financial and coefficient analysis, machine learning technologies, and open financial market data. Objectives. The aim is to create a usable toolkit for balanced evaluation of financial and economic situation of companies, based on the analysis of the main Russian and foreign modern means to measure emotions. Methods. The study employs methods of induction, deduction, and modeling. It demonstrates the link between methods and methodologies with new technical means of modern information systems. Results. The paper studies the effect of the heuristics of insufficient reaction and heuristics of excessive self-confidence, using the examples of market drawdown. I developed and implemented a model, using the behavioral finance tools as a factor in stabilizing financial decisions. Conclusions. New software and hardware tools enabled to identify and measure the actions of the heuristics of financial market participants. Financial analysts, when applying the new capabilities of modern information systems for programming and creating user models with required parameters and extensive database, will have new opportunities in the described models. The procedure for collecting and processing the original information required for valuation is simplified.

Abstract Production systems are no longer rigid, unyielding, and isolated systems anymore. They are rather interconnected cyber-physical systems with an evolution process that needs to be supported. To enable reusability in evolution, a change-first cooperative support is proposed that relies on model-based evolution steps. The approach establishes a network-wide evolution process in a peer-to-peer networked community. Thus, moving towards decentralised marketplaces for evolution steps.

The Impact

The collection and analytical work of modern intelligence services faces numerous challenges because the environment in which the services operate is characterized by the need for rapid data collection, analysis and decision-making, almost in real time. When we consider security work, the growing dependence on modern information technology makes the information structure of services sensitive and "vulnerable" to information attacks. Also, the application of information operations as a form of performing secret actions has been updated. Information technology has also changed the relationship between the service and users, introduced the possibility of applying the "pull" architecture for obtaining information, which, in addition to the good sides, also brings certain challenges. Due to all the above, the intelligence services are adapting to the technological, organizational and cultural changes brought about by the information revolution. The paper reviews the challenges in the work of modern intelligence services, primarily from the aspect of the impact of mass application of modern information technology on operational and analytical work, as well as the application of secret actions in the work of services. The aim of this paper is to point out the numerous challenges that the information revolution brings to modern intelligence services. A comparative analysis of the presented research material leads to the conclusion that the services encounter new tasks and ways of functioning in all their activities, which ultimately raises the sensitive issue of their reform. The conclusion reached in this paper is that the reform of intelligence services in the "information age" is in any case necessary, but that its implementation should not be revolutionary, but must be carried out evolutionarily.
