The need for strengthening of existing structures has recently become topical. Composite materials due to their remarkable properties, possibility to adaptation to the design requirements and facilitation of restoration measures are widely used for strengthening. This article is focused on review of restoration approaches with the use of composite materials and specific features of their behavior under various impacts. Study includes analysis of recent studies in the area, identifying gaps of knowledge and perspectives for further research.

Ways to increase the efficiency of sales activities of the enterprises of the food industry of Ukraine in the conditions of international economic activity

The food industry in Ukraine is a significant contributor to the country’s economy, with a range of products that cater to both domestic and international markets. However, the increasing competition in the global market and the changing consumer preferences have made it challenging for enterprises in the 

food industry to maintain and increase their sales efficiency. This article aims to address this challenge by exploring the ways in which enterprises in the food industry of Ukraine can enhance their sales activities in the context of international economic activity.

Economic assessment of the efficiency of use of human capital by aircraft repair enterprises

The article examines the peculiarities of the economic evaluation of the effectiveness of the use of human capital on the example of the leading aircraft repair enterprises of Ukraine. Indicators for evaluating the economic efficiency of human capital of aircraft repair enterprises are proposed. Calculations of indicators of the effectiveness of the financial provision of human capital, indicators of the economic efficiency of the construction of the structure of human capital, and indicators of the effectiveness of financing the social development of human capital were carried out.

Assessment of the efficiency of foreign economic activity (on the example of “Mohyliv-Podilskyi canning plant”

For Ukrainian enterprises today – in the conditions of war – activation of foreign trade and strengthening of its effectiveness are critically important tasks.

Implementation of foreign economic activity by enterprises is a complex process that requires not only a significant amount of resources, but also a competent approach to evaluating its effectiveness. Comparing the achieved results with previous periods or competitors allows to determine the current level of efficiency of such activity and to make the necessary changes to the company’s strategy.

On modeling a lexicographic weighted maxmin–minmax approach for fuzzy linear goal programming

In this paper, a novel approach for solving fuzzy goal programming is proposed.  This approach utilizes the weighted maxmin and weighted minmax methods simultaneously.  Relative weight is assigned to each fuzzy goal according to the preference of the decision maker.  A model for each of the two methods is separately stated; hence the two models are merged into one.  Moreover, the lexicographic maximization technique is applied to guarantee efficient solutions.  Therefore, the proposed approach allows the decision maker to compromise between the two methods.  Furthermore, the proposed approa

On some historical and legal determinants that affect the effectiveness of public control in the field of execution of punishments in Ukraine

In the article analyzes the historical and legal sources that regulated the procedure for public control over the process of execution - serving sentences, established the patterns of emergence and development of the problems existing in connection with this, and proposed some ways to solve them in essence. 

Software and algorithmic provision of parallel calculation of non-isothermal moisture transfer based on the apparatus of fractional derivatives

A new mathematical model of the nonstationary process of heat and moisture transfer in the two-dimensional region is constructed on the basis of the use of Caputo and Grunwald- Letnikov derivatives. An implicit finite-difference scheme for approximation of a mathematical model of noisothermal moisture transfer taking into account the fractional integro-differential apparatus is developed. The given algorithm of numerical realization of model allows to receive values of function of temperature and humidity for all points of area of partition.

Theoretical and applied principles of the efficiency of aviation equipment restoration

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.

Imperfection of the legislation is one of the determinants which causes a low level of public control in the sphere of enforcement of ukraine's penalties

According to the results of scientific research, when studying the content of any type of social activity, it is important to determine the socio-legal nature of the origin, development and functioning of existing problems, as well as the negative patterns that have arisen in this regard.
