The authors give a short introduction to uncertainty and introduce uncertainty terms for modular systems: Interface Uncertainty and Configuration Uncertainty. In order to control these forms of uncertainty a particular robust design methodology is needed that consists of models, methods and tools to describe, analyse, assess and finally control uncertainty. In this context, the authors provide a characterisation of what interfaces are and how they can be described through adequate properties, functions and other characteristics.
To analyse interfaces, the Contact and Channel Model is adapted to consider the main Working Surface Pairs in Working principle Sketches or rather to simplify existing interfaces aiming at a better understanding for the designer in order to make a design more robust.
Uncertainty and Interfaces, both represented in adequate models, are then brought together in one single model that can now be used to consistently describe uncertainty in the whole product lifecycle.
