Survivability is the ability of systems to minimize the impact of finite‐duration disturbances on value delivery. Previous work developed and tested a set of seventeen survivability design principles spanning susceptibility reduction, vulnerability reduction, and resilience enhancement strategies. In this paper, a process is described for applying the survivability design principles to the concept generation phase of Multi‐Attribute Tradespace Exploration, a system analysis methodology integrating decision theory with model‐based design. Applying the design principles serves both to augment the creativity of system designers by ensuring consideration of a broad tradespace of design alternatives and to quickly screen a large number of candidate design variables before proceeding to concept evaluation.
