Review of research and development of a model for optimizing tractor reliability

Abstract

Background and purpose. The premise for the study was the hypothesis of a relationship between the resource costs of tractor production and the costs of their maintenance and repair, as well as losses to enterprises in the event of tractor downtime due to breakdowns. The authors of this publication have been conducting research in this area since 2007. The article presents a generalized review of international studies within the framework of the scientific direction "life cycle engineering". The purpose of the study is to increase the profitability of agricultural production by reducing the duration of mechanized processes and resource costs.

Materials and methods. The method of expert assessments revealed the most significant factors affecting the reliability of the process of using tractors in crop production. An assessment of the consistency of expert opinions is given. Results. An analysis of the factors affecting the efficiency of agricultural tractors was carried out. An assessment of the weight of the factors is given and key components for the development of a mathematical model for optimizing costs when using tractors are identified.

Conclusion. Increasing the factory reliability of tractors reduces losses, but increases their cost, so it is important to determine rational indicators at which the total costs will be minimal.
