Abstract
The paper presents the stages of solving the problems of determining the probabilistic characteristics of stresses in technical objects with random parameters having random effects. Each of the obtained results is considered as an implementation of the random parameter under consideration (output value). Further, by methods of mathematical statistics, a probabilistic description of the parameter under study is obtained. The most complete description is the definition of the distribution law. The possibilities of automating the tasks of each stage of the solution are considered. For this purpose, it is recommended to use standard software packages Matlab, ANSYS, as well as a special regression analysis program ANETR. The description of routines, algorithms is given, commands for calculating probabilities using the ANSYS computer in interactive mode are shown.
