Aim. The development of methods of the theory of similarity and dimensionality, criterion values, as an intermediate component between theory and experiment, which ensures a functional connection between entire sets of values that characterize the process at the level of a physical model and simplify the planned experiment. Method. Processes that have a single nature of the interaction of physical phenomena can be used to build mathematical models in the study of a continuous disk dispenser.

The article is devoted to issues of developing Ukrainian economy after the war. Damage for Ukrainian economy in 2022 after the aggression of the russian federation in 2022 is enormous. Economic consequences of aggression of the russian federation for Ukraine are comparable to consequences for other countries in XX century after the wars. This fact causes the expediency of studying and using experience on the mentioned countries concerning development of their postwar economies.

The article deals with the reliability of technological machines that use hydraulic feed drives. A priority task in mechanical engineering is the design of mechanical systems with higher stability, reliability, and performance. Various mechatronic systems are used to solve this problem, including mechatronic motion modules for hydraulic drives of technological machines.

Purpose - The purpose of the article is to study esports market, analyse data on esports dynamics in the world and Ukraine and possible investment areas of esports and its investment attractiveness.

Design/methodology/approach –  Conducting the research, general scientific theoretical research methods have been used, namely, analysis, synthesis, systematization, explanation. The method of abstract and logical generalization was applied to study and analyze scientific publications, analytical reports, and legal documents.

The work is devoted to the analysis of the need for the development of solar collectors integrated into the design of the building / structure glass facade. In particular, the necessity for Ukraine to develop renewable energy sources through the parameter of energy intensity of the Ukraine gross domestic product and the physical wear of the installation in fuel-energy complex. It was analyzed that the solar energy as one of the types of generally available resources in the field of alternative technologies has been prospects for development.

This work is devoted to the construction of a mathematical model for controlling integral fire risk using correlation-regression analysis. On the basis of previous work, work is ongoing on developing a risk management method. For this purpose, the second cluster, which includes the Kharkiv region, was analyzed.

The article present the empirical mathematical model of receiving oxidized oil bitumen modified by polymeric petroleum resin with fluorine-containing functional groups. The given model allows to predict oxidized oil bitumen performance (penetration, ductility, softening temperature) without any additional experiment while changing certain process managing factors. Запропонована емпірична математична модель одержання окиснених нафтових бітумів модифікованих нафтополімерною смолою з флуорвмісними функціональними групами (НПСФ).

The essence of kvaziintegration is expanded in the article. Kvaziintegration refers to the universal (hybrid) process of corporate formation, which combines features of both integration and disintegration. This is a formal (imaginary) integration on a conventional basis, which leaves the autonomy to parts that belong to it. The advantage of this harmonious formation is a partnership and absolute competition. The phenomenon of kvaziintegration’s structure is laying in its special features – it’s adaptive, flexible, dynamic formation and focuses on tactical targets.

The article is a study of engineering in Ukraine and determine the impact of investment risk factors for the development of engineering companies.
