Abstract
The probabilistic methods find its application in engineering practice at solving of tasks when variables with random character enter in the computational model. The newly developed method, Direct Optimised Probabilistic Calculation - DOProC, appears as a very effective one for a line of tasks considering either computing time, either obtained solution accuracy. The computing procedure does not use any simulation technique and works in purely numerical way. The described algorithm has already been implemented in several applications which were successfully used at solution of probabilistic tasks and probabilistic reliability evaluations.
