Multi-Objective Planning for Healthcare Facility Resilience: Mitigate Now or Respond Later?
Gizem Toplu-Tutay, John J. Hasenbein, Matt Kammer-Kerwick +1
Flooding can damage healthcare facilities, interrupt local care capacity, and trigger costly patient evacuations. Addressing these risks requires long-term resilience investments u…
Using a generative model for out-of-sample testing of two-stage stochastic programs
Ashutosh Shukla, John J. Hasenbein, Erhan Kutanoglu
Stochastic programming models for decision-making under uncertainty often suffer from scenario scarcity, where obtaining representative samples of uncertain parameters requires exp…
Co-optimization of Short- and Long-term Decisions for the Transmission Grid's Resilience to Flooding
Ashutosh Shukla, Erhan Kutanoglu, John Hasenbein
We present and analyze a three-stage stochastic optimization model that integrates output from a geoscience-based flood model with a power flow model for transmission grid resilien…
On Simplices with a Given Barycenter That Are Enclosed by the Standard Simplex
Brent Austgen, John J. Hasenbein, Erhan Kutanoglu
We present an optimization model defined on the manifold of the set of stochastic matrices. Geometrically, the model is akin to identifying a maximum-volume -dimensional simplex…
