Short description
Discussing reliability problems in a constructive and practical manner, Robust Design Methodology for Reliability provides new principles for reliability design and the tools to put these principles into action. Featured contributions advocate testing for robustness in the early stages of product design development and consider varying uncertainties that are sometimes inherent in model assumptions for design solutions but which should not affect the system solution. Featuring vivid illustrations from real-world problems, the book shows advanced designers and reliability specialists how reliability design can relate to and work with DfSS.
