Design space exploration and optimization using modern ship design tools
(Massachusetts Institute of Technology, 2014)
Modern Naval Architects use a variety of computer design tools to explore feasible options for clean sheet ship designs. Under the Naval Sea Systems Command (NAVSEA), the Naval Surface Warfare Center, Carderock Division ...
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 ...
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 ...
A quantitative methodology for mapping project costs to engineering decisions in naval ship design and procurement
(Massachusetts Institute of Technology, 2010)
Alternative methods for cost estimation are important in the early conceptual stages of a design when there is not enough detail to allow for a traditional quantity takeoff estimate to be performed. Much of the budgeting ...
Hardware model of a shipboard zonal electrical distribution system (ZEDS) : alternating current/direct current (AC/DC)
(Massachusetts Institute of Technology, 2010)
A hardware model of a shipboard electrical distribution system based on aspects of the DDG 51 Flight IIA, Arleigh Burke class, 60Hz Alternating Current (AC) and the future direct current (DC), zonal electrical distribution ...
Open architecture framework for improved early stage submarine design
(Massachusetts Institute of Technology, 2010)
Could transparency between current disparate methods improve efficiency in early stage submarine design? Does the lack of transparency between current design methods hinder the effectiveness of early stage submarine design? ...
Exploring the use of Model-Based Systems Engineering (MBSE) to develop systems architectures in naval ship design
(Massachusetts Institute of Technology, 2010)
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, ...
Design and analysis of US Navy shipbuilding contract architecture
(Massachusetts Institute of Technology, 2015)
Contracting for US Navy ship procurement is complex due several factors such as budgetary and political concerns, sole or near sole source environments, and long lead-time construction. In the current climate of shrinking ...
Improving the parametric method of cost estimating relationships of naval ships
(Massachusetts Institute of Technology, 2014)
In light of recent military budget cuts, there has been a recent focus on determining methods to reduce the cost of Navy ships. A RAND National Defense Research Institute study showed many sources of cost escalation for ...
Absolute localization of mobile robots in forest environments by correlating ground LiDAR to overhead imagery
(Massachusetts Institute of Technology, 2014)
A method for the autonomous geolocation of ground vehicles in forest environments is presented. The method provides an estimate of the global horizontal position of a vehicle strictly based on finding a geometric match ...
