Manning and Automation Model for Naval Ship Analysis and Optimization
The manning of a ship is a major driver of life cycle cost. The U.S. Government Accounting Office (GAO) has determined that manpower is the single most influential component in the life cycle cost of a ship. Life cycle cost is largely determined by decisions made during concept design. …

Tools for Multi-Objective and Multi-Disciplinary Optimization in Naval Ship Design
… methods for measuring effectiveness in naval ship design. An Overall Measure of Effectiveness (OMOE) model or function is an essential prerequisite for optimization and design trade-off. This effectiveness can be limited to individual ship missions or extend to missions within a task group or …

Manning Analysis in Naval Ship Concept Design
The total cost of ownership of a naval ship is largely influenced by decisions made during concept design. In recent years the US Navy has undertaken numerous initiatives to reduce total ownership cost. This has prompted particular interest in reducing manning, as this is the largest single …

Network-Based Naval Ship Distributed System Design using Architecture Flow Optimization
… Architecture Flow Optimization (AFO) to naval ship Concept & Requirements Exploration (C&RE). It describes refinements to both C&RE and AFO, and naval surface combatant concept design case studies. The architectural framework decomposes naval ship distributed systems into the physical, logical, …
-
Architecture Flow Optimization - Refinement and Application for Naval Ship Concept Design
… Flow Optimization (AFO) tool for naval surface ship design, specifically focusing on the development of new network and matrix-based methods for AFO formulation and their application in Concept Development. The AFO tool analyzes and optimizes the flow of energy through the ship's Vital …
