Robust reliability is a new non-probabilistic theory of reliability of mechanical systems. It is based on information-gap models of uncertainty which express the gap between what is known and what needs to be known. The theory is applied to the analysis of an infinitely long beam which rests on a foundation with uncertain properties. The beam is subjected to a moving constant force. A numerical example shows the application of the idea to the theoretical model of the rail.
