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.
Conclusions
The development of probabilistic methods and its application in construction reliability evaluation were pointed out in this article with focus on newly developed probabilistic method DOProC. The DOProC method appears as a very effective tool for obtaining solution of probabilistic tasks, loaded only with a numerical error and error given by discretisation of input and output variables.
Also the developed program tools implementing the DOProC method were stated and which are at present able to solve a line of probabilistic calculations. The DOProC method has shown to be suitable not only for the tasks leading to reliability evaluation but also to other probabilistic calculations for which also the mentioned ProbCalc software system or other of the described sophisticated programs can be used.
