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 ...
Creating a shipboard power simulation tool using electrical load behavior modeling
(Massachusetts Institute of Technology, 2020)
Trends in power system simulation that demand computationally-intensive, physics-based models may impede the acquisition of useful results for applications like condition-based maintenance [1], electrical plant load analysis ...
Quantification of extreme event statistics in ship design
(Massachusetts Institute of Technology, 2019)
Increased operational demands on Navy vessels extend time at sea and service life, making the accurate prediction of catastrophic failures increasingly challenging. The high value of these capital assets puts great pressure ...
Automated classification of power signals
(Massachusetts Institute of Technology, 2008)
The Non-Intrusive Load Monitor (NILM) is a device that utilizes voltage and current measurements to monitor an entire system from a single reference point. The NILM and associated software convert the V/I signal to spectral ...
Improving shipboard applications of non-intrusive load monitoring
(Massachusetts Institute of Technology, 2008)
The Non-Intrusive Load Monitor (NILM) measures equipment performance by measuring and analyzing the source power to the equipment at a single point in the electrical system. Previous studies have proven the usefulness of ...
Integrated design of semi-displacement patrol crafts
(Massachusetts Institute of Technology, 2008)
Early stage ship design and assessment continues to be a challenge for naval architects and ocean engineers. The complex and multifaceted interactions between the different components of the ship and the broad spectrum of ...
Beamforming performance enhancement by adaptive hyperbola array shape estimation
(Massachusetts Institute of Technology, 2020)
Analysis of U.S. Navy Ice Exercise 2016 (ICEX16) data, through a collaboration with MIT Lincoln Laboratory, demonstrated that towed array curvature commonly exhibited heading differences up to 100° and never maintained ...
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 ...
Resilient acquisition : unlocking high-velocity learning with model-based engineering to deliver capability to the fleet faster
(Massachusetts Institute of Technology, 2019)
As the nation's security needs call for a growing naval fleet, the public-private industrial base for construction and weapon system acquisition will be stressed to perform at a high level of operational excellence. While ...
Analyzing the effects of component reliability on naval Integrated Power System quality of service
(Massachusetts Institute of Technology, 2008)
The Integrated Power System (IPS) is a key enabling technology for future naval vessels and their advanced weapon systems. While conventional warship designs utilize separate power systems for propulsion and shipboard ...
