Naval Ship Distributed System Vulnerability and Battle Damage Recovery in Early-Stage Ship Design
Abstract
Funding is provided to develop process and tools to: 1) extract primary subdivision blocks (SDBs) as axis-alligned bounding boxes from a 3D hullform anddeckhouse model (monohull and multi-hull); 2) develop and use a damage elipsoid (block) method sensitive to weapon type and charge size to assess the probability of vital component kill given hit (pk/h) for a representative number of weapon hit scenarios (250-500) and systemarchitectures represented by deactivation diagrams (RBDs); 3) assign ship compartments containing vital components to SDBs optimizing operability and vulnerability; 4) perform this process for a representative design space of ship combat and HM&E system definitions resulting in a data set of pk/h for each system combination; 5) use this pk/h data in Operational Effectiveness Models (OEMs) to assess mission MOEs and an Overall Measure of Effectiveness (OMOE) forsynthesized designs spanning the design space and created as part of a multi-objective geneticoptimization (MOGO); 6) select preferred designs from the final non-dominated set to assessbattle-damage recoverability by transitioning the simplified system models to a physics-basedmodel (PBM) testbed of vital mechanical, electrical and fluid systems; and 7) once designspecificPBMs have been created, assess the impact of idealized technology improvement to guide technology investment and evolve design PDMs over the life cycle for system validation, troubleshooting, real-time battle damage decision aids, training and upgrade.
