Data Visualizations

It is very important to visualize the initial data in a decision-making system with human participation in a proper way. Decision-making complexity, the correctness of the decisions made often depend on it. Nowadays there are many different data visualizations today such as graphs, bar charts, pie and histograms, etc. However, the situation becomes more difficult, if it comes to visualizing the dynamics of changes of structured data. Structured data is understood in this paper as data in which the observed value has an internal structure and consists of a large number of components (characteristics). This paper provides a formal description of structured data and proposes an approach to displaying the graph of their change, by which one can judge not only the general process of the observed value, but also the change in the internal structure (components included in it and their influence on human decision-making). The area of potential application of this approach, as well as its structure features and capabilities are demonstrated in the work. The description of the developed software is given for modeling the situation with the spread of COVID-19 in Bryansk region where the proposed version of visualization is used. Examples of specific situations are considered in which this approach turned out to be useful and helpful. The possibility to use the proposed method in other applied areas is described at the end of the work.

Decision Making System

The research is devoted to the development of rules for the coordination of decisions in multichannel decision-making systems. Systems are considered that in an automated continuous mode process incoming signals from different channels and, on their basis, make the final decision. One of the most problematic stages in the operation of such systems is their own coordination of solutions received from different channels. There may be cases where different channels provide signals with opposite values. Then the choice of the decisive solution should depend on the reliability of the channels under consideration. The object of research is the processes that take place during the coordination of decisions in multichannel decision-making systems. The development and implementation of such systems will allow in an automated mode to generalize the solution obtained through different channels, to increase the reliability and efficiency of the systems as a whole. During the study, the following methods were used: – a systematic approach – when analyzing the structure and functioning of multichannel one-stage decision-making systems; – method of mathematical modeling – for formalizing the problem of coordinating decisions in multichannel decision-making systems; – method of analysis – when developing rules for agreeing decisions. The authors analyzed the structure of a one-stage multichannel decision-making system. The case is considered when the channels, based on the initial data entering the system, decide on the presence or absence of a certain fact. That is, the channels send signals from the set {True, False}. In the study, decision rules for the coordination of decisions were developed, taking into account not only the signals received from different channels, but also the reliability of the channels themselves. As is usual in decision theory, different rules can give different results for the same initial data. The choice of the decision rule depends on the decision maker, its personal psychological qualities and the scope of the system.

Abstract The dual endings of Hosea promoted reflection on Israel’s history as the movement from destruction to restoration based on Yhwh’s gracious decision for Israel. It thus clarifies the endings of the prior sections of the book (chs. 3 and 11) by locating Israel’s future in the realm of Yhwh’s activities. The final ending (14:10) balances the theme of divine agency in 14:2–9 with the recognition of human decision-making and moral formation as aspects of history as well. The endings of Hosea thus offer a good example of metahistoriography, a text that uses non-historiographic techniques to speak of the movements of history.
