Systematic trade-off strategies for balancing survivability and mobility in vehicle design

Ground Combat Vehicles (GCV) use a combination of firepower (i.e. lethality), mobility, and survivability to perform safely their expected mission.The Line of Effort 1.2 of TARDECs 30-year strategy focuses on protected mobility and in providing mission appropriate balance of survivability and mobility technologies.Diverse mission profiles must also be considered, representing peer or asymmetric enemies engaged in various battlespaces, and GCV architectures that can adapt to the continuously changing geopolitical threats are desired.A Survivability Assessment Metric (SAM) capability will be developed for providing a holistic view for the ability of a vehicle to survive an engagement.A probability tree diagram will be used for computing the SAM by representing the different phases of an engagement and depicting the possible outcomes for each phase, along with the corresponding probabilities for each of the outcomes.In this research, the SAM will be used by a Set Based Design methodology for fully exploring and morphing the design space while understanding the implications that diverse mission requirements have on the potential solutions.In this manner decision makers can avoid focusing early in a single solution that meets the requirements of a single battlespace but fails under other operating conditions.
