The functionality of modern structural, mechanical and electrical or electronic systems depends on their ability to perform under certain conditions. Consideration of uncertainties and their effect on system behaviour is an essential and integral part of defining systems. In 11 chapters, leading experts present an overview of the current state of uncertainty modelling, analysis and design of large systems in four major areas: finite and boundary element methods (common structural analysis techniques), fatigue, stability analysis, and fault-tolerant systems. It describes research developments...
