Flexibility, Complexity, and Controllability in Large Scale Systems
(Massachusetts Institute of Technology. Engineering Systems Division, 2014-03)System structure is a key determinant of system behavior. There is a particularly strong link between a system’s structure and its flexibility – it’s capacity to respond to changes. Often, adding flexibility entails adding ... -
A Framework for Technology Forecasting and Visualization
(Massachusetts Institute of Technology. Engineering Systems Division, 2009-10)This paper presents a novel framework for supporting the development of well-informed research policies and plans. The proposed methodology is based on the use of bibliometrics; i.e., analysis is conducted using information ... -
Framework for the Analysis of the Adaptability, Extensibility, and Scalability of Semantic Information Integration and the Context Mediation Approach
(Massachusetts Institute of Technology. Engineering Systems Division, 2009-04)Technological advances such as Service Oriented Architecture (SOA) have increased the feasibility and importance of effectively integrating information from an ever widening number of systems within and across enterprises. ... -
Framing the Climate Debate: Knowledge Affirmation vs. Risk Mitigation
(Massachusetts Institute of Technology. Engineering Systems Division, 2011-03)Opinions regarding the anthropogenic climate change hypothesis (ACC), along with the possibility of subsequent catastrophic environmental impacts, often break down along ideological lines that have lead to a dichotomy ... -
Gas-Electricity Coordination in Competitive Markets under Renewable Energy Uncertainty
(Massachusetts Institute of Technology. Engineering Systems Division, 2013-10)As climate concerns, low natural gas prices, and renewable technologies increase the electric power sector’s dependence on natural gas-fired power plants, operational and investment models for gas and electric power systems ... -
GDP-Based Productivity in Ambulatory Healthcare: A Comparison with other Industry Segments, 1998-2005
(Massachusetts Institute of Technology. Engineering Systems Division, 2008-02)Few studies have focused on productivity in healthcare, let alone in ambulatory healthcare. Measurement of productivity in various healthcare segments has generally shown that productivity has either decreased (over some ... -
Global Comparison Aggregation Services
(Massachusetts Institute of Technology. Engineering Systems Division, 2002-12)Web aggregation has been available regionally for several years, but this service has not been offered globally. As an example, using multiple regional comparison aggregators, we analyze the global prices for a Sony ... -
Global Outsourcing of Professional Services
(Massachusetts Institute of Technology. Engineering Systems Division, 2006-08)As a growing number of firms outsource more of their professional services across geographic and temporal boundaries, one is faced with a corresponding need to examine the long-term ramifications on business and society. ... -
Growing Towards a Sustainable Biofuel Future: A Comprehensive Policy Strategy for Navigating Tradeoffs and Stakeholder Interests in U.S. Agriculture
(Massachusetts Institute of Technology. Engineering Systems Division, 2008-03)Rapid growth of biofuels production in the United States is reshaping the agricultural industry, delivering both benefits and conflict among stakeholders. Routes forward on biofuels production should be viewed in the context ... -
Growth Patterns of Subway/Metro Systems Tracked by Degree Correlation
(Massachusetts Institute of Technology. Engineering Systems Division, 2011-08)Urban transportation systems grow over time as city populations grow and move and their transportation needs evolve. Typical network growth models, such as preferential attachment, grow the network node by node whereas ... -
Heterogeneity and Network Structure in the Dynamics of Diffusion: Comparing Agent-Based and Differential Equation Models
(Massachusetts Institute of Technology. Engineering Systems Division, 2004-11)When is it better to use agent based (AB) models, and when should differential equation (DE) models be used? Where DE models assume homogeneity and perfect mixing within compartments, AB models can capture heterogeneity ... -
Heterogeneous Unit Clustering for Efficient Operational Flexibility Modeling for Strategic Models
(Massachusetts Institute of Technology. Engineering Systems Division, 2013-01)The increasing penetration of wind generation has led to significant improvements in unit commitment models. However, long-term capacity planning methods have not been similarly modified to address the challenges of a ... -
Hiring College Graduates to Flip Hamburgers: An Endogenous Theory of Professionalization
(Massachusetts Institute of Technology. Engineering Systems Division, 2014-03)In this paper, we offer an endogenous theory of professionalization and ever-higher degree attainment. We theorize that higher education is a self-driving growth engine. We introduce two endogenous mechanisms that act on ... -
The Historical Roots of the Field of Engineering Systems: Results from an In-class Assignment
(Massachusetts Institute of Technology. Engineering Systems Division, 2012-03)The field of Engineering Systems (ES) is quite young but there are intellectual roots that go far back in time.
