Applying Function-Based Failure Propagation Analysis in Conceptual Design
Abstract
When designing a product the earlier the potential risks can be identified, the more costs can be save, as it is easier to modify a design in its early stages. Several methods exist to analyze the risk in a system, but all require a mature design. However, by applying the concept of "common interefaces" to a functional model and utilizing a historical knowledge base, it is possible to analyze chains of failure during the conceptual phase of product design. This paper prensents a method based on these "common interfaces" to be used in conjunction with other methods such as Rish in Early Design in order to allow a more completed risk analysis during the conceptual design phase. Finally, application of this method is demonstrated in a design setting by applying it to a thermal control subsystem.
