Abstract
This study reviews existing research on optimizing the reliability of agricultural tractors, with a focus on identifying the most critical factors influencing tractor performance. The methodological approach involved an expert assessment of factors affecting tractor reliability, which highlighted three key elements: the factory (inherent) reliability of tractors, the effectiveness of repair and maintenance practices, and the losses incurred from tractor downtime. The consistency of expert opinions was validated using an agreement coefficient. Based on these findings, the development of a mathematical model is proposed, enabling agricultural enterprises to make informed decisions when selecting tractors based on reliability and cost-efficiency indicators. This research represents the initial phase of a broader project, with future plans to create software that automates the optimization of tractor reliability and costs, ultimately improving the profitability of agricultural enterprises
