The article deals with the issues of typification of elements of irrigation systems in land reclamation. When designing irrigation systems it is necessary to take into account measures for the agricultural development of reclaimed lands. The natural and economic conditions of the irrigation area, the characteristics of the irrigation source, the irrigation area and its configuration affect the composition of the irrigation system elements, their location, network design, and in each specific case change the irrigation system. Typical technological elements of irrigation systems allow to design quickly the system taking into account the features. In this regard, a nomenclature of typical technological elements of irrigation systems was proposed, consisting of 6 modules. An analysis of the range of controlled parameters on each module in the design and calculation version was also carried out.

The article has devoted to solving an urgent problem related to the analysis of the quality of manufacturing sprockets for chain drives of agricultural machinery. For the conditions of a technical service enterprise specializing in the maintenance and repair of agricultural machines, an experimental assessment and analysis of the quality of spare parts - sprockets, which have a fit on the shaft of the H090 gearbox of the Mosselmash plant. It had revealed that the factory set the requirements for the inner diameter of the sprocket Ø30H7(+0.021). Measurements of the hole of 100 stars had carried out, as a result of the analysis of the experimental data obtained, the following had established: scattering parameters and quality parameters for manufacturing controlled dimensions. Using empirical data, a histogram and a theoretical curve for the distribution of the internal diameters of the sprocket had constructed. It had revealed that the probability of the appearance of suitable parts is 83%, parts with a correctable defect − 8%, with an unrecoverable one − 9%. On the basis of the obtained data, in order to improve the quality of manufacturing chain sprockets, appropriate recommendations had made to the manufacturer.

The article discusses the issues of ranking the assortment of Russian-made cognac using ABC analysis. ABC analysis allows you to select the most significant objects from the whole set of the same type, that is, to select objects that are few, but which need to be paid close attention to. To rank the cognac assortment, an ABC analysis was conducted, which showed that Group A cognacs are in the greatest demand, bring the greatest profit, so they should always be in stock. The second group includes cognacs that are in stable demand among consumers, which also indicates good sales and profits. The presence of Group B cognacs is also important for the company, but cognacs of this group can be modeled at a calmer and moderate pace. Group C - has the lowest demand from consumers. The reason is the high price of goods of this group, since not every consumer can afford to buy high-quality cognac. To improve the assortment and improve the quality of brandies sold by companies, it was proposed to expand the range of cognacs by introducing new names and types, which will help attract new consumers; take into account factors affecting the development and formation of the range of cognacs.

The article deals with the mechanism of quality control of agro-industrial production processes, namely, quality control of poultry farm processes. It also details the management of nonconforming products using simple quality control and management tools – a checklist and a Pareto chart. It was suggested that a checklist should be used to record nonconformities and their number for each nonconformity. Using this checklist form will allow you to analyze the production process, identify the causes of nonconformities, and quickly intervene in the process to prevent nonconformities from occurring. To analyze the inconsistencies and the causes of their occurrence, it was suggested to use the Pareto diagram, the use of which allows you to pay attention to the most significant problems.

This article contains substantiation of the improvement of inspection instruments used for the repairs of farming machinery during incoming quality inspection, in-process inspection, and acceptance testing. The design of a gauge plug has been developed for repairs and with the purpose of inspection of bushing bores of the intermediary shaft bearing with the diameter of Ø48.8F7 for ZMZ engines. The manufacturing tolerance for go-side and no-go side has been determined. The deviation of the middle of the tolerance range in relation to the smallest limiting size of the gauge plug was 3.5 μm. The permissible overrun of a worn-out of the gogauge outside of the tolerance range border was – 3 μm. The manufacturing tolerance for the size of the check caliper gauge has also been determined and limiting dimensions of the check gauge have been calculated. Taking into account the values derived a layout for the gauge plug tolerance range has been developed in order to inspect the bushing bores of the intermediary shaft bearing with the diameter of Ø48,8+0,050 +0,0025.

The article has devoted to a topical topic, includes the modeling of technological processes for the cultivation of crop products. As an object of research, the process of cultivation of fodder lupine had chosen. The analysis of the process of cultivation of crop products from the point of view of the Deming cycle has carried out. The production of feed lupine has presented as a system of interrelated processes. A passport of the process «Production of fodder lupine» has been developed, which contains brief information about the projected process: inputs, outputs, resources, control mechanisms, etc. The top-level model «Production of fodder lupine» in IDF0 notation has developed. The developed model can be used as the basis for building a quality management system for lupine cultivation. The proposed approach will allow to achieve the quality of the crop and achieve the set goals.

The article presents a mechanism for analyzing the costs of the process from the point of view of assessing the effectiveness of the functioning of the quality management system at mechanical engineering enterprises of repair profile. The analysis of the costs of the process can be carried out in four directions: analysis of the effectiveness and efficiency of the process, analysis by type of costs, analysis of the effectiveness of measures to improve the process, comparison of the amount of costs for compliance and losses from non-compliance with the main economic indicators of the economic activity of the enterprise. Each direction can be applied independently, but in order to achieve reliable results and optimize the cost of quality, it is necessary to analyze the cost of quality in the four proposed directions. We analyzed the costs of repairing KAMAZ engines in four directions and came to the following conclusion: the introduction of a process cost management system allows us to timely identify process inconsistencies and take measures to eliminate them and reduce the risk of occurrence in the future, it is necessary to increase the amount of preventive costs in order to shift the break-even point right, it is necessary to take measures that actually prevent the occurrence of possible problems, the costs of compliance and losses from inconsistencies in sales are significant, therefore, measures should be taken to identify, analyze and assess the risk of inconsistencies in production and corrective actions to reduce the share of costs in total sales volume.
