Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
Uncertainties in technical systems in the field of mechanical engineering occur during the entire life cycle of a product. In general these uncertainties are understood as deviations from the process and product properties. This fact makes it necessary to develop a comprehensive methodology for the analysis of uncertainties in the product life cycle, which is called Uncertainty-Mode- and Effects-Analysis (UMEA). It is a strategic procedure to analyse the uncertainties and their consequences. These uncertainties can be generated for example by different processes operations or by load changes 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 Uncertainty-Mode- and Effects-Analysis methodology is based on a comprehensive life cycle model of uncertainty, which allows the consideration of uncertainties in all life cycle processes systematically, to describe and to evaluate the impact of uncertainties systematically in a standardized fashion.
