Reliability-based Optimization Robust Design of Electronic System

摘要：

The theory of reliability sensitivity analysis and reliability-based optimization robustdesign are extended to discuss the reliability design of electronic system.Firstly,a method ofmeasuring the relative importance (sensitivity analysis) of each element of system is studied.Andthen,after establishing the mathematic model for reliability optimization,a procedure for robustdesign is examined.Finally,a numeric example is presended to illustrate the procedure of sensitivityanalysis and robust design.After optimization,the mean life of system has increased than before,andthe cost has been greatly reduced; on the other hand,the sensitivity of system reliability to the meanlife of components also has decreased.The result shows that the proposed methodology is useful forsystem design and quality improvement.
