Systems Theoretic Process Analysis applied to an Offshore Supply Vessel dynamic positioning system
(Massachusetts Institute of Technology, 2016)
This research demonstrates the effectiveness of Systems Theoretic Process Analysis (STPA) and the advantages that result from using this new safety analysis method compared to traditional techniques. To do this, STPA was ...
Strategies to reduce product waste in the consumer packaged goods industry
(Massachusetts Institute of Technology, 2015)
The cost of waste for products such as soft drinks, shelf stable dry food, and dairy in the consumer packaged goods industry is massive, about $15 billion annually in the U.S.A. This thesis focuses on waste associated with ...
Power shifts : a techno-economic analysis of multinational electricity market development in the Middle East
(Massachusetts Institute of Technology, 2018)
Electricity demand has been rising rapidly in the six Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates). As a result, the diversification and sustainable ...
Carbon dynamics of global land use, land-use change, and forestry
(Massachusetts Institute of Technology, 2018)
Forest harvest for bioenergy is growing rapidly, spurred by the European Commission's declaration that bioenergy is carbon-neutral. Bioenergy advocates argue that the carbon released upon the combustion of harvested wood ...
Intellectual property and architecture : how architecture influences intellectual property lock-in
(Massachusetts Institute of Technology, 2017)
Intellectual property lock-in is a wicked problem particularly pervasive under monopsony market structures, such as the Department of Defense (DoD). However, little research exists on the mechanisms of action that induce ...
Accounting for non-hazardous industrial waste in the United States
(Massachusetts Institute of Technology, 2016)
This dissertation presents a method for estimating the tonnage and composition of non-hazardous industrial waste (NHIW) flows in the United States. For thirty years, it has been an accepted fact that NHIW is generated at ...
Modeling human attention and performance in automated environments with low task loading
(Massachusetts Institute of Technology, 2016)
Automation has the benefit of reducing human operators' workload. By leveraging the power of computers and information technology, the work of human operators is becoming easier. However, when the workload is too low but ...
Potential housing bubble with Chinese characteristics : analysis and policy design through an operational model
(Massachusetts Institute of Technology, 2018)
This thesis analyzes the potential housing bubble in the Chinese urban housing market. Using an operational model built on system dynamics (SD), it explores the unique housing market structures, information flows, key ...
Improving trade visibility and fidelity in defense requirements portfolio management
(Massachusetts Institute of Technology, 2014)
In 2003, the Department of Defense (DoD) requirements process migrated from a bottom-up, threat-based force-planning method to a capability-based, top-down approach with the introduction of the Joint Capabilities Integration ...
Greenhouse gas equivalency metrics for evaluating energy technologies
(Massachusetts Institute of Technology, 2017)
This thesis addresses a long-standing question about how to compare energy technologies that emit different types of climate forcers during their life cycles. This problem is challenging because these forcers have dissimilar ...
