The theoretical and methodological foundations of the digital transformation of marketing and advertising in the agro-industrial complex of the Republic of Kazakhstan are explored. The need to transition from traditional marketing tools to digital communication models in the conditions of climate instability, territorial scale of markets and institutional constraints in the agricultural sector is justified. A systematic analysis of the economic nature of marketing costs is carried out and a functional classification is proposed, which reflects the main purpose of managing communication costs. Special attention is paid to the analysis of mathematical, statistical and evolutionary methods for optimizing marketing and advertising budgets. The scientific novelty of the study lies in substantiating the feasibility of using multi-criteria evolutionary algorithms (NSGA-II, NSGA-III) to manage digital marketing strategies of agricultural enterprises. A research hypothesis and practical recommendations are formulated for using the results obtained in the strategic management system of agricultural enterprises.

The current evolution of disseminated computer program frameworks is characterized by a growing adherence to the principles of service-oriented engineering (SOA). Simultaneously, these frameworks are becoming more intricate, with an increasing number of components and more complex data connections between them. This situation underscores the importance of employing mechanisms to unify artifacts in the process of developing composite web services, which govern, among other aspects, the architectural plane of the frameworks under construction. A model for constructing composite web services is suggested as a suitable tool, implemented in accordance with a hierarchical approach, intended for use in designing distributed systems. Model is constructed over an assumption that coordination of the components of a composite web service is carried out in a centralized manner. in accordance with the orchestration model. To implement formalization and obtain, based on analytical representations, the corresponding software implementations, it has been decided to use the DEVS mathematical apparatus. The aspect of software implementation is considered pivotal in determining the feasibility of automating the acquisition of composite web services that operate within the orchestration model. Obtained research results has been interpreted as a conrmation of the eectiveness of this approach on the basis of the scenario of querying the database. Resulting artifacts have been represented with UML notation. The relationship between analytical representations and corresponding software implementations has also been demonstrated. Usage of the DEVS Suite tools has made it possible to visualize the process of simulation - to obtain estimated values of the indexes of the resulting solutions

In the modern conditions of developed information systems, the advantages of creating virtual private networks cannot be underestimated. But before mentioning the clearest and most useful ways to create virtual private networks, it is necessary to understand its meaning. Nowadays, the question of how to communicate with the corporate information system is important for users. Here they will need a broadband connection, regardless of whether they use a fixed network or Wi-Fi, as it is not uncommon for users to work on the road. Today, virtual technologies are becoming more popular, they occupy a high place in modern companies. Because they allow you to prevent the voice server from connecting to one workplace. It is not always necessary to keep employees in the office to get information about the services, there is no need to be there, it is enough to use a remote connection. Many institutions have implemented a fixed or mobile solution, which provides effective connection of mobile employees through the terminal. Many networks are now connected via the Internet. Therefore, it is necessary to take certain measures for the security of such a large system, because any computer can gain access to the network of any institution, the risk of breaking the computer is much higher without any physical effort

The article provides an overview and analysis of mathematical models for choosing investment strategies in cybersecurity systems of informatization objects (IO) as a particular example of educational information systems (IS). The purpose of the work is the analysis and comparison of known and new investment models for the IO protection. It is shown that previous researches have often purely economic nature and do not take into account the trends relating to the introduction of innovative information technologies in the control and decision-making procedures of the IO cybersecurity tasks. It is shown that the optimal value of resources allocated for the IO protection and cybersecurity depends not only on the vulnerabilities of IS, but also on the cost of information should be protected. All this makes it relevant to develop new models for the decision-making support on the IO protection and cyber-security investment. The task, in particular, can be solved through the use of new information technologies and computer-based decision support systems (DSS). As a variant, it was proposed to use as a basic mathematical model for DSS the models based on game theory.
