Maintainability of individual assembly units in mechanical engineering

In the presented work, author analyzed indicators and characteristics of maintainability large units assembly heavy engineering products. The calculation operational distribution law recovery maintenance time are given. paper shows that random nature production factors predetermined widespread use in theory reliability mathematical apparatus methods probability, functions statistics. particular, their application to describe changes state devices, analytical determination statistical assessment characteristics. relevance this work is possibility practical adaptation for decomposed with varying degrees detail. results form recommendations operation mechanical
