Abstract

Elements of Teaching Uncertainty in Design Engineering design requires skills of not only analysis but also judgment and experience.The consideration of several factors including efficiency, reliability and cost assessment is alsocritical. However, these factors are influenced by another key factor: uncertainty. Hence, thebasic understanding and implementation of uncertainty in design among respective highereducation engineering students should be given the proper focus. Several major industry nowroutinely consider uncertainly in design, since this is the basis of warranty, reliability, and riskassociated with complex technologies. Preliminary assessment of design curricula of severalinstitutions revealed that only a few higher institutions in the US have courses in their curriculumthat address design under uncertainty (DUU). This implies that the importance of teachinguncertainty in design has been overlooked by the majority. This research proposes possibleoptions of integrating uncertainty in the curricula of design and studies its effectiveness. Theimportance and practical applications of DUU are discussed and exemplary institutions withinfrastructure and curriculum for teaching DUU and their experiences are assessed. This paperpresents the effectiveness of DUU to enhance students’ understanding of mechanical systemdesign and discusses the implementation of such course in higher institutions. Performance ofstudents both in design classes and in other hands-on projects show that those who have takensuch courses demonstrated better understanding of the problems at hand and they were also ableto provide better and pragmatic solutions. Finally, sample curricula of typical courses withsuggestions of corresponding infrastructure and recommendations on their implementation arepresented.
