“…However, there is always the danger of misclassification, which can potentially lead to incorrect voting results of multiversions and incorrect decision-making about the correctness of their output. This can significantly affect the operation of the software package and the failure of the control system for objects that are critical in terms of reliability, which is noted by many authors, for example, in [8][9][10][11].…”

The task of improving the algorithms for making decisions about the correctness of the states of multiversions is relevant today for the development of fault-tolerant software systems. The article considers a class of decision-making algorithms that are implemented in the execution environment of multi-version program modules. This execution environment includes a decision block, which, based on the principle of voting, allows you to get the correct decision at the output, filtering out the erroneous results of the execution of software versions. Advanced algorithms allocate the output results of multiversion triggering into classes or subsets, which are then analyzed for correctness. This approach is characterized by the fact that it allows you to increase the stability of the runtime environment to interversion errors. This, in turn, helps to improve the fault tolerance of software systems used in reliability-critical applications.

In the article, based on the concept of increasing the reliability of the formed image of the complex of technical means for ensuring the operation of an unsolicited measuring station of the network of stations of the ground control complex, a solution is proposed for choosing the general scheme of an uninterruptible power supply as part of a complex of technical means of unsolicited measuring systems. The uninterrupted power supply system is designed to automatically provide a set of technical means for ensuring the operation of a non-demand measuring station with a guaranteed and uninterrupted power supply in accordance with the indicators of reliability, autonomy and quality of electricity specified in the terms of reference. A procedure for selecting the constituent elements of an uninterruptible power supply is proposed, the main stages and composition of the protection means for the power supply network are considered. A block diagram of protection over the power supply network is presented. It is noted that structurally, the uninterruptible power supply should be able to be placed both in a stationary room and in a block container.

“…требует надежной обработки информации, что, в свою очередь, предъявляет высокие требования по надежности к программным средствам [1][2][3][4][5][6][7][8]. Очевидно, что компьютерные системы мониторинга и контроля объектов, работающих в режиме реального времени, играют очень важную роль в обеспечении их безопасности, поэтому всегда существует потребность в высококачественном программном обеспечении [9][10][11][12].…”

“…Надежность программного обеспечения является одним из измеримых аспектов качества программного обеспечения [11][12][13]. В отличие от аппаратного обеспечения, ПО не стареет, не изнашивается и не ржавеет, поэтому ненадежность программного обеспечения в основном связана с ошибками в коде программ или конструктивными/структурными ошибками в программном обеспечении.…”

The article provides an overview of approaches to the analysis of the transactional structure of software in systems for monitoring fault-tolerant objects. These objects, as a rule, are distributed and operate in real time. It is shown that computer systems for monitoring and controlling objects operating in real time play a very important role in ensuring their safety, so there is always a need for high-quality software. The aim of the work is to increase the efficiency of the analysis of the transactional reliability of software systems for information processing and monitoring by automating the simulation of the life cycle of the transactional structure of the software. Modeling the life cycle of a software transactional structure is primarily associated with the formalization of its processes and stages, as well as with the use of a methodology that allows describing the semantics of the processes and stages of the formation, implementation and maintenance of software. For visual modeling of the life cycle of the transactional structure of the software, the IDEF0 methodology is used, which allows you to build a functional model of the life cycle and describe the rules of this model, that is, the logical relationships between works.
