Aspects of assessment of organizational and technical reliability and design of construction processes with target reliability level using computer-aided technologies
This article concentrates on the aspects of assessment of reliability of organizational and technical decisions in construction processes, using computer-aided technologies. The methodical approach and algorithm of the software module solving the problem of evaluation of organizational and technical reliability of construction and design processes with a given level of reliability are presented in this article. A special feature of the approach is separation of the sample values of a random value (initial for determining the intensity and duration of the construction process — time rates per unit volume of works or performance) into two parts of values: those satisfying the conditions of the construction process on scheduled date and unsatisfying ones. This allows, in respect of the appropriate value for the initial design parameter, calculating the probability that rates or performance, and therefore the corresponding values of intensity and duration of the construction process at the end of implementation of the construction process time would not be more or less than the design values. This approach reveals a possibility of constructing algorithm to solve a set task by means of computer technology presented in the article. Based on the proposed algorithm, a software module was developed with the Technologist software package in order to solve problems of designing of building production on variant and probabilistic basis.
