On some features of determining product quality on the example of the data of one of the leading domestic automakers

The article proposes a method for describing the probability distribution density of the failure-free operation of a product in the form of a two-parameter exponential function. Based on the data of one of the leading domestic car manufacturers, examples are considered and an assessment of the obtained theoretical distributions is carried out. In this work, to assess the quality of products, it is proposed to use the indicator of the average time spent on warranty service and car repairs during the first year of its operation.
