Flexibility in early stage design of US Navy ships : an analysis of options
(Massachusetts Institute of Technology, 2011)
This thesis explores design options for naval vessels and provides a framework for analyzing their benefit to the Navy. Future demands on Navy warships, such as new or changing missions and capabilities, are unknowns at ...
Ship design through Axiomatic Design approach, sustainable engineering principles and artificial intelligence methods
(Massachusetts Institute of Technology, 2021-06)
Environmental sustainability, as well as social and economic well-being, must be considered in every stage of a product lifecycle, from conceptual design to its retirement. Even though this sustainability-centric approach ...
Vulnerability analysis of an all-electric warship
(Massachusetts Institute of Technology, 2010)
Traditional design processes usually rely on cost as the metric the designer uses to select among different alternatives. Sometimes when costs cannot be calculated we use weight, volume and efficiency as surrogates for ...
Investigating the Use of Inductive Transfer Learning and RNN to Quantify Extreme Event Statistics of Ship Motions
(Massachusetts Institute of Technology, 2023-06)
Ship motion software has been a critical tool for designers to study the extreme responses of ships in irregular waves. These studies and simulations often take thousands of hours to predict and analyze the ship’s motion. ...
A Method for Organized Institutional Learning in the Navy Shipbuilding Community
(Massachusetts Institute of Technology, 2022-05)
The implementation of a Set-Based Design (SBD) process by the U.S. Navy’s DDG(X) program was observed by the author beginning in June of 2020. Capturing knowledge and lessons learned is an important part of the SBD process. ...
Naval Submarine Maintenance: An Examination of Areas of Potential Availability Execution Risk
(Massachusetts Institute of Technology, 2022-05)
In the growing 'Great Power Competition' of the 21st century, the US Navy has faced near-peer competition that it has not experienced in several decades. This competition has ultimately resulted in increased operational ...
Quantifying Flexibility in Naval Ship Design
(Massachusetts Institute of Technology, 2022-05)
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 ...
Hydrodynamic Interactions of an Unmanned Underwater Vehicle Operating in Close Proximity to a Moving Submarine
(Massachusetts Institute of Technology, 2021-06)
While the United States Navy has developed a strong arsenal of tools to model the hydrodynamic forces and moments of different vehicles in different conditions, they do not have a model that enables them to understand the ...
