“…And if, until recently, IT technologies were used mainly in the field of personnel and financial management, now digital technologies are used in the design, production and maintenance of products to optimize processes, reduce costs and produce defective products (Erohin et al, 2019a). But the introduction of digital technologies requires a certain level of knowledge from technologists, which is not enough in the labor market (Erohin et al, 2019b). Therefore, it is necessary to introduce the most automated technologies for conducting business processes.…”

Studied in the article the impact of digitalization on the efficiency of technological processes of modern production. The research was carried out at a specific enterprise that produces meat products. It turned out that despite the fact that many enterprises currently use modern technological lines with a high degree of automation, they still distrust the digital counterparts of production processes. Creating a digital double of a production line, although it requires specific applied knowledge, is not an impossible task. The next stage of digitalization is the simulation of processes that allows you to identify the time and material resources used, as welll as fixed costs. Conducted basic, semi-automated and automated modeling options. Research has showen that emi-auttomated systems can come close to automated ones in terms of theur capabilities, thereby ensuring an increase in labor productivity and laying the foundation for further development in the form of accumulated data and highly efficient processes.

“…Methods and means of research. When determining the arithmetic mean, standard deviation, and a number of other characteristics, methods of mathematical statistics and probability theory had used [1]. In order to determine the measurement error and its components, standard metrological evaluation methods had used.…”

“…And the measuring instruments used here are, most often, universal measuring instruments for linear dimensions. But even when repairing machines, it is necessary to control the complex geometric dimensions of body parts, their deviations in the shape and location of surfaces [1,2], and also to select parts in sets by weight [3].…”

Issues related to the evaluation of the results of direct multiple measurements with a worn digital micrometer have considered. It had determined that the total error of the device used in operation exceeds the limit of permissible error indicated in the passport by 1.25 times and is equal to 5 μm. But in the field of control of parts in repair production, the passage of mandatory verification by measuring instruments is not required, and the calibration operation is advisory in nature. Based on the obtained value, we can conclude that the device can be used to measure the dimensions of parts with a tolerance of at least 15 µm.

“…An analysis of existing methods for calculating losses due to measurement error showed that all of them are purely theoretical and do not take into account the specifics of a particular technological process (Wu, 2013). A feature of modern engineering production is the appointment of such tolerances that allow for a certain margin of accuracy in the joints (Leonov & Shkaruba, 2019;Leonov et al, 2020c), as well as the necessary accuracy of dimensional chains (Erokhin et al, 2021), but at the same time there is a decrease in tolerances, an increase in the accuracy of processing and, as a result, the need to use more accurate measuring instruments.…”

Many enterprises, including repair ones, face the problem of losses due to measurement errors. It has established that the number of losses from the measurement error has affected by the type (error) of the measuring instrument used, the dispersion of the controlled parameter (the distribution law, the scattering zone), and the features of the technological process. The article presents a generalized theoretical mathematical model developed by the authors, which describes the procedure for the formation of losses from measurement errors. The developed model has adapted in relation to repair production, using the example of controlling the diameters of the main journals of the crankshaft of the YaMZ-238 engine. The approbation of the developed technique made it possible to determine the losses from the measurement error in the control of the root diameters of the crankshaft journals using various measuring instruments. It has established that the greatest losses have obtained when using measuring instruments with the largest error, and the smallest -with the smallest error. The use of a more accurate measuring instrument instead of the recommended one will reduce the losses from the measurement error during the input control of new crankshafts in the repair shop by more than 77%.
