Reliability-directed computer-aided design system

A theoretical approach and applied techniques for designing analogues engineering devices and systems with due account of random variations in system parameters and reliability specifications are considered. For solving this problem a so-called operational/parametric approach is used. This approach is based on the computer-aided simulation of system capability and availability, parameter deviations and techniques of optimal parametric synthesis in terms of reliability criteria. Special attention is paid to algorithms that reduce the labor content of parameter optimization problems. For seeking a numerical solution of the parametric design problem a computer-aided reliability-oriented design system is proposed
