Computer-automated sensitivity analysis in reliability-based plastic design
Computers & Structures, 1986Abstract The evaluation of the total probability of a plastic collapse failure Pf for a highly redundant structure of random interdependent plastic moments acted on by random interdependent loads is a difficult and computationally very costly process.

Sensitivity studies in reliability-based analysis of redundant structures
Structural Safety, 1985Abstract A description is presented for extending computer-based methods of reliability analysis of structural systems so that both the magnitude and the sensitivity of the global safety of such systems are included in the results. In particular, redundant ductile structures are studied and the interest is mainly focused on obtaining the sensitivity ...

Reliability-Based Sensitivity Analysis for Machining Precision by Saddle-Point Approximation
Applied Mechanics and Materials, 2012Based on the saddle-point approximation theory, the reliability sensitivity formula is derived systematically. Then, combining the reliability theory with the sensitivity analysis method, the reliability-based sensitivity of machining precision for ball-end milling cutter is analyzed.

Sensitivity Analysis on the Influence Factors of Software Reliability Based on Diagnosis Reasoning
2013There are some uncertain factors (i.e. environment factors) in the software development process which have direct or indirect influence on software reliability. This paper uses the Bayesian network to construct the software reliability qualitative evaluation topology structure based on the environment factors and analyzes the sensitivity of these ...

2014 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2014
Through the sensitivity analysis of large-scale grid reliability, we can determine the key equipment influencing the power supply reliability of the system, and thus effectively find out the bottlenecks limiting the system reliability. In this Paper, the circuit outage model is established, and the former complex large-scale grid with various ...

Reliability based structural optimization requires a combined usage of numerical methods for structural reliability analysis and structural optimization. In analyses presented in the literature the approach has been to use nested analyses, where the structural reliability analysis is done within the structural optimization analysis. This means that the

Applied Thermal Engineering, 2019
Abstract In the present work, the reliability-based sensitivity analysis of a shell and tube heat exchanger has been investigated. Four optimum heat exchanger layouts have been selected among the available layouts in literature as case studies (which optimized based on the GA, PSO, ICA and BBO algorithms).

Quality and Reliability Engineering International, 2011
AbstractMost of physical parameters of high temperature components are usually correlated with the temperature parameter, which makes the reliability‐based structural optimization design more complicated. So far, few efficient sensitivity analysis methods adapted to highly nonlinear performance function with correlated non‐normal variables have been ...

Parametric Sensitivity Analysis of Fuzzy Reliability Based on the Cut-Set of Fuzzy Mathematics
Key Engineering Materials, 2010The problem of the parametric sensitivity of fuzzy reliability analysis was discussed in this paper. Firstly, based on the concept of cut-set of fuzzy mathematics, a computational model is introduced. Then, the expression of cut-set of fuzzy mathematics is built in the case of normal random stress and normal fuzzy strength, and the effect of each ...
