Reliability Optimization Analysis based on Structure of Probabilistic Model Xiangfu Liu Science College and Institute of Intelligent Vision and Image Information, China Three Gorges University, Yichang, Hubei, 443002, P.R.
The inherent reliability is the reliability of the manufacturer of the product design must be established, that in accordance with the planning of the reliability, from the selection of raw materials and parts, design, manufacturing, testing, until the various stages of the product produced by the established reliability.
Durability Sufficient durability of the structure in a predetermined working environment within a predetermined time period, the deterioration of the material properties will not cause the structure unacceptable failure probability.
Without uncertainties include probabilistic uncertainty analysis probabilistic model of uncertainty, the uncertainty of the physical and mechanical model, the cross-section resistance of the basic assumptions of the formula and calculation model inaccuracies and human neglect and material properties, geometric parameters error.
