Popis: Decisions made during the conceptual phase of the design process are crucial for long-term economic success. The correction of late-identified failure is often both difficult and time consuming, and may have a negative effect on performance. In the prevalent design methodologies, there are shortages concerning systematic and objective methods to evaluate solutions with respect to weak spots and errors, especially early in the design process. The objective of this article is to strengthen the evaluation methodology by examining the possibilities to identify potential problems within conceptual solutions, and to develop a means that facilitates the evaluation regarding this matter. The results presented in this article may be divided into two parts: a descriptive part where a generic approach of modelling the failure behaviour is proposed and a prescriptive part where a foundation of a methodology for identification of potential failure is outlined.
