      The attacks of September 11, 2001 revealed national security vulnerabilities that had previously not received high level priority in the United States, such as insecure transportation and infrastructure networks. In response, ...
    • Bits and Bucks: Modeling complex systems by information flow 

      Lloyd, Seth (Massachusetts Institute of Technology. Engineering Systems Division, 2002-05)
      This paper presents a general method for modeling and characterizing complex systems in terms of flows of information together with flows of conserved or quasi-conserved quantities such as energy or money. Using mathematical ...
    • Bodies, Ideas, and Dynamics: Historical Perspectives on Systems Thinking in Engineering 

      Mindell, David A. (Massachusetts Institute of Technology. Engineering Systems Division, 2002-05)
      Today, the idea that technology consists not simply of individual machines but of systems of components and interconnections underlies much of engineering theory and practice. Yet this idea is relatively new in the history ...
    • Building Real Options into Physical Systems with Stochastic Mixed-Integer Programming 

      Wang, Tao; de Neufville, Richard (Massachusetts Institute of Technology. Engineering Systems Division, 2005-06)
      The problem of building real options into physical systems has three features: real options are not as easily defined as financial options; path-dependency and interdependencies among projects mean that the standard tools ...
    • Bulk Power Grid Risk Analysis: Ranking Infrastructure Elements According to their Risk Significance 

      Koonce, A. M.; Apostolakis, George; Cook, B. K. (Massachusetts Institute of Technology. Engineering Systems Division, 2006-09)
      Disruptions in the bulk power grid can result in very diverse consequences that include economic, social, physical, and psychological impacts. In addition, power outages do not affect all end-users of the system in the ...
    • Capacity pricing schemes to implement open-access rail in Tanzania 

      Pena-Alcaraz, Maite; Perez-Arriaga, Jose Ignacio; Sussman, Joseph M. (Massachusetts Institute of Technology. Engineering Systems Division, 2014-06)
      We analyze alternative capacity pricing schemes (access charges) to implement an open-access railway system in Tanzania. We show that the implementation of variable access charges widely used in the railway industry may ...
