DMDU: Decision Making under Deep Uncertainty

Mission Statement

To advance the methods, tools, and practice of decision-making under deep uncertainty in transportation planning, enabling more robust and responsible decisions in a rapidly changing world.

Goals

We are modelers, so this initiative takes a model-centric view of DMDU, but a big part of DMDU is moving the focus away from model forecasts and towards getting to better decisions! We seek to:

  • Complement predictive applications of models with insights generated from exploratory applications
  • Promote use of models in concert with decision makers and stakeholders
  • Facilitate an adaptive planning process where multiple futures are considered and immediate steps are taken to maintain flexibility and resiliency

Community Engagement

  • To join the group, please contact us.
