“…To address these challenges, methods of safety-based system design and concept-stage failure analysis are proposed in the literature (Leveson, 1995;FAA, 2000;Johannessen et al, 2001;NASA, 2004;Stone et al, 2005;Hutcheson et al, 2006;Jensen et al, 2008;Jensen et al, 2009;Kurtoglu et al, 2010;Mutha et al, 2010aMutha et al, , 2010bMutha & Smidts, 2011). The objectives are to generate and evaluate system designs where safety and risk are addressed early in the design process.…”
