The analysis of statistical parameters for the production of agricultural machinery and parameters characterizing the reliability and quality of domestic tractors is carried out. It is shown that the organization of a system for collecting and processing information on the reliability of products is important from the point of view of quality and reliability of tractors. The experience of creating such a system is considered as exemplified by PJSC “Promtractor”.
The paper presents an example of mathematical modeling of the process of reproducing units of physical quantities by installations of the highest accuracy and their transfer to measuring instruments in the form of a non-stationary service system. The use of non-stationary service systems makes it possible to evaluate the efficiency of the process under overload conditions at the directive interval, as well as to evaluate the most important characteristics of the functioning process, for example, such as the probability of failure to perform reproduction and transmission of units of values by installations of the highest accuracy in a timely manner, etc.
The article analyzes the data on the management of the technical condition of agricultural machinery objects, presents basic information on warranty service of products of public joint stock company “Promtractor”, provides diagrams showing the procedure for work from the date of delivery of products to the buyer until the end of the warranty period for products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
