The analysis of the reliability of products remains an urgent task, especially when it comes to radio electronics products produced in small batches, when traditional methods of mathematical statistics are ineffective. In this case, it is advisable to use methods combining statistical and physical approaches. For example, a statistical-physical method, when by the type and values of the parameters of the distribution of the moments of failure of the product, an assumption is made about its possible causes. The purpose of the article is to consider the possibility of a statistical-physical approach using mixtures of different distributions to describe the time dependence of the failure rate.

As a result, a statistical-physical method of reliability analysis based on a model described by a mixture of exponential and Weibull distributions is substantiated. Examples of using the proposed method on specific products are given.
