Quantifying Flexibility in Naval Ship Design
Warships are highly complex and complicated systems that are designed in the present to address problems that will exist decades in the future. Because of the significant time gap between preliminary design and the end of the ship’s service life, it is critical that it be built with flexibility in …

Dynamic Architecture Flow Optimization for Capability-Based Assessment of Naval Ship Design
… tool for Combat, Power, and Energy System (CPES) design in naval surface ship concept development. As a continuation of earlier work, the DAFO has been refined using matrix-based methods with further development towards implementing capability-based design. The DAFO responds to capability requests …

Real options for naval ship design and acquisition : a method for valuing flexibility under uncertainty
… surface combatant capability. This new system of ships must be deigned to meet the uncertainty associated with constantly changing required mission capabilities, threats, and technological advances. Flexibility in design and management will enable these systems to maximize their performance under …

Exploring the use of Model-Based Systems Engineering (MBSE) to develop systems architectures in naval ship design
The U.S. Navy designs and operates the most technologically advanced ships in the world. These ships incorporate the latest in weapons technology, phased array antennas, composite structures, signature reduction, survivability, modularity, power systems, computing systems, and automation. The modem …
