Identification of Potential Failure: On Evaluation of ConceptualDesign
2009 (English)In: Journal of engineering design (Print), ISSN 0954-4828Article in journal (Other academic) Submitted
ldentifying and attending to faults and shortcomings in the design before it reaches the market is crucial in order to achieve a profitable product. Letting the customer detect the shortcomings in the design is not an acceptable approach today, and will inevitably lead to unsatisfied costumers. Activities aimed at identifying faults in the product may becarried out during the entire design process, but faults identified late in the design process will require more resources to put right, and may affect the performance negatively to a higher degree than faults identified upstream in the process. This article aims to develop the theory and methodology regarding identification of potential failures in a system upstream from the design process. The result presented in this article comprises a method for modelling failuresand a process for identirying potential failures in conceptual solutions. The result is based onqualitative system modelling, where the known physical phenomena are compared to the system in order to evaluate the potential of different behaviour occurring. The effects the behaviour emits determine its impact on the system, and thus the potential for a failure. The article concludes with a comprehensive example demonstrating, and to some extend verirying, the method of identifying potential failures.
