Cost prediction via quantitative analysis of complexity in U.S. Navy shipbuilding
(Massachusetts Institute of Technology, 2014)
As the sophistication and technology of ships increases, U.S. Navy shipbuilding must be an effective and cost-efficient acquirer of technology-dense one-of-a-kind ships all while meeting significant cost and schedule ...
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 ...
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 ...
Using the principles of set-based design to realize ship design process improvement
(Massachusetts Institute of Technology, 2016)
Set-based design (SBD) is a relatively new complex product development method. Its use has been well researched in the automotive and aerospace industries and, although it requires an upfront investment in resources, it ...
Applying set based methodology in submarine concept design
(Massachusetts Institute of Technology, 2010)
Early stage ship design decisions continue to be a challenge for naval architects and engineers. The complex interactions between the different elements of the ship and the broad spectrum of disciplines required in ship ...
Using polymer electrolyte membrane fuel cells in a hybrid surface ship propulsion plant to increase fuel efficiency
(Massachusetts Institute of Technology, 2010)
An increasingly mobile US Navy surface fleet and oil price uncertainty contrast with the Navy's desire to lower the amount of money spent purchasing fuel. Operational restrictions limiting fuel use are temporary and cannot ...
Naval ship propulsion and electric power systems selection for optimal fuel consumption
(Massachusetts Institute of Technology, 2011)
Although propulsion and electric power systems selection is an important part of naval ship design, respective decisions often have to be made without detailed ship knowledge (resistance, propulsors, etc.). Propulsion and ...
Model testing and computational analysis of a high speed planing hull with cambered planing surface and surface piercing hydrofoils
(Massachusetts Institute of Technology, 2015)
As part of a 2014 thesis, the MIT Innovative Ship Laboratory (iShip) designed a high-speed planing hull form that was based on the Model Variant 5631 developed at the US Navy's David Taylor Model Basin [7] [3] [5]. This ...
Naval applications of enhanced temperature, vibration and power monitoring
(Massachusetts Institute of Technology, 2015)
Navy ships require reliable information regarding their power and mechanical systems in order to perform their mission effectively. While today's shipboard systems are quite sophisticated, there are areas for improvement ...
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 ...
