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 ...
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 ...
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 ...
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 ...
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 ...
Automation as a manpower reduction strategy in navy ships
(Massachusetts Institute of Technology, 2016)
Since the early 2000's, the US Navy has endeavored to decrease the Total Ownership Cost (TOC) of their ships through a decrease in Operating and Support costs. This led to a large-scale effort by ship program managers to ...
