Using the structural fault-tolerance index in project designing

Abstract

The problems of improving the efficiency of the design process and decision-making processes support at the design stage are considered. In particular, proposed is to use an information structural statistical model under conditions of heterogeneity and incompleteness of the initial data about the design object elementary basis characteristics. Due to the modeling object’s morphological similarity it allows to analyze the object’s structural reliability by estimating the failure-free operation probabilities. Proposed are several variances to define the reliability function type depending on the statistical sampling set scattering power and options of structural resiliency index calculation. The proposed structural information statistical model allows to conduct the real-time statistical experiment removing at each step one element of the model structure. It also allows to calculate the probability of failure-free operation index on the average value.
