The article discusses the results of research in the field of developing a system that in real time allows you to display and remotely transmit the main technological parameters of indentation of factory-made piles (values of indentation forces, number and depth of immersed piles, their displacement relative to the design position). Unlike existing analogues, it allows you to additionally guide the installation of the indentation on the dive points of piles without instrumental removal of their position on the ground. This is done by orienting the installation through a global satellite navigation system. And the position of the piles is set automatically by calculating their coordinates obtained from the project in dfx format, previously entered into the memory of the on-board computer. The constituent elements of such a system are presented, as well as the interface for setting up and displaying technological parameters. The main technological indicators of the process in remote mode can be displayed on the display of any mobile device. It is shown that the cost of such a system is 8 % of the cost of the installation of the indentation of piles. It has been established that it pays off by reducing costs with the subsequent strengthening of grillage structures. These additional works are eliminated due to the prompt elimination of identified deviations, as well as improving the accuracy of installation of piles in the design position. The article presents an algorithm for performing work when setting up the system, receiving and transmitting relevant information. It is shown which participants at different stages will be involved in these processes. In conclusion, various performance indicators for the implementation of such a system are presented. Based on the results of the timing, it is proved that its use allows to reduce the duration and labor costs of both the production of works and the preparation of executive documentation. In addition, the information obtained can be integrated into the building information model, which will allow analyzing the operational reliability indicators of pile foundations.

It has been proposed to use the analysis method of the operating environment to assess the effectiveness of small agricultural enterprises based on the two input factors characteristics (resources) – labor costs of enterprises, the cost of equity and the resultant factor – the volume of sales. Coefficients of coverage by volume of sold products (goods, works, services) of own capital cost and labor costs for small agricultural enterprises by types of economic activity have been calculated, which allowed types of economic activity rating by small enterprises by coefficients of coverage of sold products (goods, works, services) cost of capital, labor costs and financial results. It has been proved that the activity of small agricultural enterprises among all other types of economic activity has the highest rating on the coefficients of coverage of sold products (goods, works, services) of labor costs, but the lowest on the coefficients of coverage of sold products (goods, works, services) capital, despite the fact that the amount of profit is inferior only to economic entities engaged in wholesale and retail trade; repair of motor vehicles and motorcycles. Using the coefficients values of coverage of the sold products volume (goods, works, services), the cost of equity and labor costs, built an environment for small agricultural enterprises, which allowed to form a line of technical efficiency: (agriculture, forestry and fisheries-wholesale and retail trade; repair motor vehicles and motorcycles-information and telecommunications-education) and on the basis of the position of agriculture, forestry and fisheries to find a new position by designing a line with the position of inefficient economic activity (Activities in the field of administrative and support services). It has been outlined the possibility of optimizing the activities of small agricultural enterprises by increasing the volume of sold products (goods, works, services) and reducing costs, which will improve the financial result (will increase profits).

The aim of the study is to increase the efficiency of vehicle operation by establishing patterns of change in the performance properties of winter tires and improving, on this basis, methods for adjusting the frequency of their replacement. The research methodology is based on the application of a systematic approach, a number of private methods of the experimental-theoretical level and proven methods of processing experimental data. As a result of the analysis of key factors, the relevance of the application of repair technology for studding car tires has been substantiated. Experimental studies on measuring the braking distance and acceleration time have confirmed the need for prompt diagnostics of the residual number of studs on car tires. It was found that the efficiency of the tire as the actual number of studs decreases non-linearly and depends largely on the type of road surface used. The scientific novelty of the performed research is the regularities of braking and acceleration properties of cars operated on various road surfaces in winter conditions, taking into account the technical condition of studded tires. The practical significance of such stands is to increase the demand for this service by reducing costs and significantly reducing labor costs associated with assessing the performance of winter tires. Technological operations using portable stands can be combined with periodic maintenance or carried out with a seasonal tire change both at service stations and in motor transport companies. Further research is aimed at collecting, analyzing and systematizing data to establish the parameters of mathematical models of the most popular standard sizes of automobile winter tires, which will allow scaling the technology and reducing its cost due to mass use. Thus, the results of the on-line diagnostics of tires can be used by car owners when making timely decisions about replacement or repair, which significantly increases traffic safety and reduces the cost of operation, since if the integrity of the tread is preserved, the restoration of winter tires with repair studs almost completely restores the original properties that determine numerical values of efficiency indicators at significantly lower costs in comparison with buying a set of new tires.

Neglect of soils leads to their degradation, worsens useful properties, and reduces fertility and productivity. (Research purpose) The research purpose is in conducting a comparative analysis of technologies for treating degraded soils, taking into account the economic feasibility of their restoration in non-black-soil regions of Russia. (Materials and methods) The article shows the main technological scheme of restoration of degraded soils. Authors have identified the main groups of land that are located in non-black-soil regions of Russia. (Results and discussion) The article presents the need for equipment, economic and labor costs for the restoration of each type of land in the non-black-soil regions of Russia. Authors took into account that the salary of machine operators depends on the time of direct execution of the task. It was found that the restoration of virgin and fallow lands was the most preferable from the economic, energy-saving and environmental points of view. The article shows that the restoration of pasture areas exceeds the cost of processing virgin lands, but the number of necessary machine and tractor units is comparable to work on virgin lands. Authors recommend to develop the soils with woody and shrubby vegetation in the first place, starting with land occupied by young plants. It is necessary to take into account the criteria for the fertility of the soil layer. It was found that soils with a small excess of moisture have small cost of its development, while on heavily swampy soils the cost of work on their development is many times higher than the cost of restoring other types of land. (Conclusion) The article shows that the restoration of neglected land is a necessary condition for improving the provision of human needs for food and a number of industrial goods. First of all, it is necessary to develop land that requires minimal investment of economic and labor costs.

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

Abstract Nowadays, maintenance is based on the synergistic integration of operational reliability and timely maintenance, which guarantees the required availability and optimal cost. Operational reliability implies producing more, better performance, longer life, and availability. Timely maintenance involves the least time out of service, fewer maintenance costs, fewer operating costs, and less money. In this work, we study the preheating train of a crude distillation unit of a refinery, which processes 994 m3/h, which presents a formation of a fouling layer inside it. Among the impacts of fouling is the reduction in the effectiveness of heat transfer, the increase in fuel consumption, the increase in CO2 emissions, the increase in maintenance costs, and the decrease in the profit margin of process. An appropriate cleaning program of the surface of the heat exchanger network is necessary to preserve its key performance parameters, preferably close to design values. This paper presents the maintenance method centered on energy efficiency, to plan the intervention of the preheating train equipment maintenance, which considers the economic energy improvement and the cost of the type of maintenance. The method requires the calculation of the fouling evolution from which the global heat transfer coefficient is obtained, and the heat flux is determined as a function of time. It was observed that, as time passes, the resistance provided by fouling increases and that the overall heat transfer coefficient decreases. The energy efficiency centered maintenance has an indicator of economic justification (factor J) that relates the economic-energy improvement achieved when performing maintenance, taking into account the economic effort invested. Depending on the cost of the type of maintenance to be performed, a threshold should be chosen, from which the maintenance activity is justified. The effectiveness values of the heat exchanger (ε) and the J indicator are used to form a criticality matrix, which allows prioritizing maintenance activities in each equipment. The planning of the implementation dates of the maintenance of each heat exchanger, from the maintenance method centered on energy efficiency applied to the crude distillation unit’s, preheat train, constitutes a contribution in this specific field. The conceptual design of the maintenance method centered on energy efficiency presented in this work is feasible for other heat transfer equipment used in oil refineries and industry in general. The procedure developed uses real operation values, and with its implementation, a saving of 150000 US dollars was achieved.

Increasing the productivity and efficiency of agricultural cargo transportation in the agro-industrial complex of the Russian Federation is achieved through the use of tractor trains consist-ing of tractors and trailer links, the main of which are trailers. This method allows you to ensure the quality and safety of agricultural goods, as well as reduce the cost of transportation. During the analysis of the known designs of tractor-trailer dump trailers, it was revealed that a character-istic drawback is the imperfection of the design of the locking elements of the platforms designed to fix them on the chassis. As a result, a promising technical solution was developed, which, in comparison with the known ones, has a simple design and increased efficiency when fixing the bodies on the chassis. The article describes the design and the principle of operation of this tech-nical solution. The results of the structural strength calculation are presented. The conducted check showed that the obtained value of the safety factor, equal to 2.2, will ensure the operational reliability of trailed dump vehicles. The results of the study are recommended to both domestic and foreign research institutes, design and production structures of the automotive industry for further study and refinement of the proposed device with a view to its possible implementation in practice.
