Article
Complex systems operating beyond their expected life or usage can yield scenarios where the current requirements that must be met were “unknown” at the time of their original design. Such “unknown” requirements might be outside the probability distribution expected during the design phase or, more drastically, might not have been predicted. Enginee...

Conference Paper
A widely held belief in engineering design is that the optimal design is the one that satisfies all requirements at the lowest cost. Recent research has begun challenging this notion by arguing that a system’s total lifetime value may be improved by designing for uncertain future requirements, even after considering additional incurred costs. Exces...
