<p>The structural scheme is developed and the description of the bioengineered quasimolecular algorithm of scenario analysis of dynamics of variation series is presented. On the basis of this algorithm a complex of pessimistic, inertial and optimistic scenarios of connection of search activity of Internet users and general morbidity coronavirus infection were developed and verified. Correlation relations between the intensity of search queries on the topic &laquo;distance learning&raquo; of relative frequencies of search queries on various communicative information technology platforms have been evaluated. It has been found that the distribution of Internet users' search queries on coronavirus theme has the character of a chain branching process, which testifies to the phenomenon of &laquo;infodemia COVID-19&raquo;.</p>

Modern information technologies provide text manipulation processes with high efficiency. First of all, this means storing, editing, and formatting texts and their components. Having achieved significant success in developing tools for content-free computer text processing, researchers faced problems with their content processing. Therefore, further steps in this direction are associated with the creation, among other things, of methods for automated purposeful manipulation of texts, taking into account their content. The analysis of works devoted to the study of the problems of formal presentation of texts and their subsequent use is carried out. Despite a number of successful projects, the challenges of solving the problem of the relationship between the content of the text and its meaning remain relevant. It seems that formalization of a General-purpose text while preserving its semantics is not feasible at this stage. However, there are types of texts that can be formalized while preserving their semantics. One of them is a regulatory text type, which is essentially a verbally expressed algorithm for a sequence of targeted actions. It is distinguished by logic and accuracy (lack of allegories), coherence and integrity, clarity, understandability (due to the lack of emotional coloring and figurative means), accessibility (due to the use of specific terminology). In other words, when developing regulatory texts, they usually try to display the mechanisms of the described actions as clearly as possible. Purpose: development of a method for formalizing a regulatory text while preserving its semantics. Methods: structural linguistics, representation of objects in the form of an ontology, constructive algorithms. The use of this method is demonstrated by describing the solution of a system of algebraic equations. Results: method for constructing a mathematical model of a regulatory text. Practical relevance: the application of the developed method makes it possible to develop software systems for building libraries of individual subject areas, develop tools for evaluating regulatory texts for their certainty, completeness, connectivity and other characteristics, as well as simulators and self-learning tools.

The materials reflecting the authors' study on the problems of improving the activities of the modern school are presented. Based on the analysis of the emerging new labor structure of society, a generalized system of modern education is proposed. The key place allocated to it in the system of general education is emphasized. The main problems of the modern secondary school in general and the management of its activities in particular are considered. The main attention is paid to the formation of the ranking of schools, which includes indicators of diverse characteristics. It is proposed to consider the educational institution as a social system, within the framework of which the students develop skills of behavior, relationships in the team and with the external environment. It is noted that in each educational institution, an internal organizational and psychological culture is formed, which leaves its mark on almost all the processes taking place there, in particular, it creates restrictions on the possibility of making certain decisions and the likelihood of their implementation. This position necessitates the formation of a school-specific system of consistent indicators, including a number of qualitative indicators. The use of such indicators in school management processes necessitates the development of specialized methods for assessing the effectiveness of its activities. The article proposes a method for assessing qualitative characteristics, providing an increase in their level of objectivity.

The issues of assessing the probability of the implementation of the developed enterprise activity plan are considered. The use of a constructive simulation method is proposed, which provides the possibility of developing software complexes for automatic development of plans with a full set of estimates of their characteristic indicators, including the probability of the plan implementation, on a single methodological basis.
