Chapter Chapter 7 in Risk-Based Engineering, 2018, pp 237-270 from Springer Abstract: Abstract The traditional approach to design is conservative and rule based (i.e., prescriptive) and uses point estimates of design parameters while employing factors of safety to account for uncertainty in data, models, and other sources of knowledge. This approach, even though it is time-tested and proven, does not provide any quantified statement on design reliability or safety or, conversely speaking, the risks associated with failures. The other drawback of this approach is that it tends to result in relatively overdesigned parameters in terms of volume/weight or size ratio and further overburdens the connected systems and, at times, performance. This approach is basically conservative and prescriptive in nature which makes the whole design process rigid in nature. The principles of defense in depth, redundancy, diversity, and single-failure criteria are employed in the design to incorporate safety. However, it may be noted that “risk,” be it at qualitative level, remains the main driver for system designs.
