recovery

This research article is devoted to the topical issues of restoration and modernization of Ukraine
in the post-war period, the study of strategies for the restoration and reconstruction of economic and
social structures in the regions of Ukraine that have been devastated by the war with russia. The research
is based on the analysis of the experience of other countries that have experienced similar challenges, as
well as on the study of successful practices and possible failures in the implementation of recovery

На основі аналізу механізмів забезпечення відмовостійкості програмних засобів запропоновано шляхи вдосконалення розподілених модулів відновлення. Визначено особливості побудови систем із використанням обраного механізму, запропоновано аналітичні вирази оцінки ефективності механізму розподілених модулів відновлення та досліджено його ефективність.

The results of the enterprise's economic activity are multifaceted and depend on many factors. Under such conditions, it becomes more and more difficult to evaluate the obtained results of the enterprise activity. This is especially difficult to do in the aviation industry, since the complexity of aviation equipment and the tragic consequences of its malfunction significantly complicate the calculation of the economic efficiency of the aviation equipment restoration.

The article is devoted to the study of the essential characteristics and interrelationship of the main concepts of the categorical apparatus of the economic evaluation of the restoration of aviation equipment. Peculiarities of the approach of various authors to the definition of the concept of aircraft repair are analyzed. It has been established what types of repairs are used during the operation of aviation equipment. The economic advantages and disadvantages of using various types of repair for aviation equipment are determined.

The problem of the conditions definition of the transition from the corrective recovery to the planned recovery strategy of an uninterruptible power supply, while a reliability is kept on the same level, is considered in this paper.
We consider the uninterruptible power supplies (UPS), which have a modular structure of the power supply unit (PSU). They are designed as a fault-tolerant systems (FTS) with N+M and 2×(N+M) redundant configurations, where N - is number of the PSU modules required to power the workload, and M - the number of the redundant modules.

After heating and cooling, water heating is typically the second largest user of energy in the home. There are a lot of purposes and uses of hot water in buildings - showers, tubs, sinks, dishwashers and clothes washers etc. In most cases, these hot waste waters are discarded direct to sewer system. When we take into the account all of these purposes in every households, the wastewater retains a considerable portion of its initial energy – energy that could be recovered and used.
