The systematic treatment of uncertainties in the simulation of complex processes is a rapidly growing field. As technical systems are increasingly operated at physical limits, uncertainties due to a lack of knowledge, the manufacturing process and environmental conditions can have an undesirable effect on system behavior. Such uncertainties can be taken into account at an early stage in computer simulations. This is done, for example, by combining stochastic methods with established simulation methods (such as finite elements) and requires interdisciplinary work between the fields of engineering, mathematics/statistics and computer science.
