The work is devoted to the problems of strategic planning in the digital technology market. The aim of the work is to build a decision support procedure for choosing a strategy, based on internal (related to the characteristics of the firm choosing the strategy) and external (conditioned by the state of the market) factors. It is assumed that the elementary strategy is described by the type, direction and applied area of activity. In this case, the possibility of combining several elementary strategies is considered. The main result of the work is a procedure for choosing a combined strategy based on the application of a genetic algorithm. The use of the methodological apparatus of evolutionary calculations is due to the large number of possible options for combined strategies and the complexity of their evaluation, which makes a complete enumeration of options impractical. The final choice is made by the decision maker based on their own preferences.

The work is devoted to the problems of using modern digital technologies to manage the implementation of programs for the development of regional socio-economic systems. An approach based on the use of intelligent (knowledge-oriented) informationsystems for monitoring and analyzing the progress of programs is proposed. As a model for representing knowledge about the subject area, it is proposed to use the apparatus of the theory of linguistic variables and fuzzy production rules, which makes it possible to take into account the high level of uncertainty due to both the specifics of socio-economic processes and possible changes in external conditions. The inference engine included in the information system is based on the explicitly interpreted procedure of Mamdani's fuzzy logical inference, which makes it possible to form explanations of the course of reasoning. The developed structure of the intellectual information system is a concretization and expansion of the traditional structure, taking into account the reflection of the specifics of the tasks of managing the implementation of programs for the socio-economic development of the region. The preliminary results of the experimental operation of the research prototype of the developed system can serve as confirmation of the effectiveness of the proposed design solutions.

The problem of representation of the structure of the domain, which could be used in automatic summarization is described in this paper. As a solution to this problem, the authors propose to use a denotat-based text analysis technique , developed by A.I. Novikov and his school (Institute of Linguistics). This technique was the basis of the proposed infological model that makes it possible to view the structure of a particular subject area, and ultimately the creation of a system of automatic summarization.
