“…There are several design approaches that propose frameworks for addressing system survivability that include both (1) the integrated engineering framework (Ellison et al 1997) and (2) the bio-networking architecture (Nakano and Suda 2007). However, the most impressive work has been done by Mathew Richards and his colleagues at the Massachusetts Institute of Technology (Richards et al 2008(Richards et al , 2009 in which they focus on the development of design principles that address each of the three survivability elements. Table 11.7 displays the three survivability elements and the associated design principles that may be invoked when addressing survivability as a purposeful activity during system design endeavors.…”

“…To improve the generation of survivable design alternatives, seventeen survivability design principles spanning susceptibility reduction, vulnerability reduction, and resilience enhancement techniques were empirically-derived from military and commercial aerospace systems. 4,5 To improve the evaluation of survivability in tradespaces, metrics were developed to assess survivability as a dynamic, continuous, and path-dependent system property. 6 These respective efforts enable consideration of survivability strategies that prevent losses across the entire disturbance lifecycle and an ability to rapidly filter thousands of design alternatives in tradespace studies.…”

Multi-Attribute Tradespace Exploration (MATE) for Survivability is introduced as a general methodology for survivability analysis and demonstrated through an application to a satellite radar system. MATE for Survivability applies decision theory to the parametric modeling of thousands of design alternatives across representative distributions of disturbance environments. Survivability considerations are incorporated into the existing MATE process (i.e., a solution-generating and decision-making framework that applies decision theory to model-based design) by applying empirically-validated survivability design principles and value-based survivability metrics to concept generation and concept evaluation activities, respectively. MATE for Survivability consists of eight iterative phases: (1) define system value proposition, (2) generate concepts, (3) specify disturbances, (4) apply survivability principles, (5) model baseline system performance, (6) model impact of disturbances on dynamic system performance, (7) apply survivability metrics, and (8) select designs for further analysis. The application of MATE for Survivability to satellite radar demonstrates the importance of incorporating survivability considerations into conceptual design for identifying inherently survivable architectures that efficiently balance competing performance metrics of lifecycle cost, mission utility, and operational survivability. Nomenclature A T= threshold availability ∆V = change in velocity, m/s k i = multi-attribute utility scaling factor for attribute i TAT = time above critical value threshold, years T dl = time of design life, years U e = emergency utility threshold (zero by definition), utilities are dimensionless U i (x i ) = single-attribute utility function over attribute x i U ‾ L = time-weighted average utility loss from design utility, U 0 ‾ U t = time-weighted average utility U(t) = utility delivery over time; multi-attribute utility trajectory U(x) = multi-attribute utility function over attributes x at a point in time U x = required utility threshold

“…To incorporate survivability considerations into conceptual design, this paper introduces an approach for deploying an existing set of seventeen survivability design principles during concept generation (Richards et al 2008a). As discussed in previous work, the intent of the design principles is to enhance concept generation by expanding the set of system design tradeoffs under consideration.…”

“…Results from these iterative mappings identified missing design principles and taxonomic imprecision in design principle definitions-informing an expanded set of seventeen design principles. The design principle set stabilized in subsequent empirical tests (e.g., Iridium satellite system, F-16 combat aircraft) (Richards, Ross et al 2008a). Table 1 categorizes and defines the seventeen design principles.…”

Abstract. 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.
