Within the scope of current research, the scientific and applied problem of balancing multisubject polyfactorial environments of software products’ complex support was considered, in the context of a more global scientific and applied problem of automation and intellectualization of the complex support of software products, as well as a human-machine interaction. The relevant object of research in this work – is the process of balancing multisubject polyfactorial environments of software products’ complex support.

Nowadays, with the rapid development of modern technologies in software engineering, active digitalization, and the migration of many services online, ensuring the security of these services in terms of integrity, confidentiality, and availability of information has become more important than ever. The level of application security directly depends on investments made in security during software development.

A review of publications devoted to the mathematical simulation of the nanofiltration process was carried out, the advantages, limitations, and areas of application of various modeling approaches were determined. It was found that the most effective approaches are based on the extended Nernst-Planck equation, Donnan equilibrium, as well as methods of computational fluid dynamics and molecular dynamics. The use of software for solving nanofiltration simulation problems was considered.

In the modern world, where information security becomes a key element of any organization's operations, software security testing automation is more important than ever. The success of an application directly depends on its stability, reliability, and security, which makes the proper implementation of control mechanisms critical. The increase in cyber threats and the growing complexity of software systems make this topic even more relevant.

The article analyses the literature sources, which investigate the existing methods and means of calculating reliability indicators of complex technical (in particular, software) systems. The reliability model of a modern complex technical system is often depicted in the form of a reliability block diagram (RBD), which may contain thousands of elements, each transitioning between different states (e.g., operational, failed, restored). This leads to a vast space of possible states in the corresponding Markov model.

This article proposes an original approach at a mathematical level to the creation of multi- objective quality models for software systems. The research is based on the study and generalization of quality modeling trends of software systems and user needs in order to determine optimal principles for constructing such  models. The article provides mathematical explanations that play a key role in identifying and formalizing the principles of creating multi-objective quality models of software.

A problem of navigation within large educational complexes has been identified, which poses a particular challenge for new students, visitors, and staff. It has been established that the implementation of augmented reality technologies considerably enhances the intuitiveness and usability of the navigation system. A comprehensive structural and mathematical model of the navigation system based on augmented reality technologies has been meticulously developed.

The work carried out a comparative analysis of scientific publications regarding the possibility of predicting the direction of the cryptocurrency exchange rate using the data of open numerical indicators, based on the results of which it can be concluded that due to the volatility of the cryptocurrency market and the need for accurate forecasting, there is a need to create an aggregated indicator that will take into account the current price exchange rate asset, parameters of simple indicators, trading volume, etc.

The existing means of calculating reliability indicators of software systems are analyzed. It has been established that to determine the reliability indicators of software systems, it is advisable to use the structural-logical analysis of reliability block diagrams, since it clearly and most adequately reflects the process of calculating the reliability indicators of the software system as a whole and its components in particular.
