【 摘 要 】

In reliability theory, there is often a need to establish a relationship between parameters non-observed simultaneously. An example of such parameters is the operating time of the same product in different modes, because it's impossible to experience the same product before destruction in several modes. In carrying out such destructive testing, the following question often arises: how to determine the operating time of a product in some specific, set mode, knowing the time of operation of this product in a different mode. By «mode» in this case a certain condition types for testing construction products are implied, for example, various climatic conditions, loads affecting the building construction, as well as other external influences in which the work of the product is possible. In practice, this problem is reduced to the investigation of the truth or falsity of the hypothesis that the operating time of the product in the first and second modes ( 1 and2) depends on some function , chosen on the basis of a qualitative analysis of the problem. Since in real conditions when determining the reliability of products you often deal with samples of small size, in this paper we investigated the admissibility of applying the technique for calculating the reliability of building structures and products for small samples. The simulation results are shown in tables and are graphically depicted.
