Abstract

In mechanical engineering uncertainties occur during the entire life cycle of a product. These uncertainties are defined as deviations from process and product properties. This makes the development of a comprehensive methodology for analysing uncertainties necessary. The methodology is called Uncertainty Mode and Effects Analysis (UMEA) and consists of a strategic procedure to analyse uncertainties and their consequences. These uncertainties appear for example by different process operations or by variations during the utilization process of the product. In planning and development processes uncertainties must be taken into account particularly in the modelling and forecasting of the technical, environmental and economic product and process properties. The integrated UMEA methodology is based on a comprehensive model of uncertainty, which allows the consideration of uncertainties in all life cycle phases to describe and to evaluate the impact of uncertainties systematically.
