In engineering, reliability modélling is the process of predicting or understanding the reliability of a component or system.

Two separate fields of investigation are common.

The physics of failure approach uses an understanding of the failure mechanisms involved, such as crack propagation or chemical corrosion.

The parts stress modelling approach is an empirical method for prediction based on counting the number and type of components of the system, and the stress they undergo during operation.
