Practical challenges in the applications of DMDU

By Tania Lopez-Cantu Throughout progress in scientific discovery and technological advancement, engineers and scientists have learned how to approach modeling of a specific physical phenomena bounded by a set of unknown but well-defined rules or choosing the best alternative out of a constrained set of possible alternatives. Under these and…

DMDU and Critical Infrastructure Systems

By Sibel Eker Infrastructures are critical for the smooth functioning of socioeconomic systems on Earth – “daily life” as we know it. Whether in urban or rural areas, or in the developed or developing world, our ordinary activities — from a phone call to food deliveries, from switching on the…

Exploring How Our Models and Modelling Shape Scenario Discovery

By Patrick Reed Institutionally complex water resources systems have evolved globally to deal with omnipresent challenge of hydrological variability and extremes. The evolving vulnerability and resilience of these systems is a challenging scientific question for model-based decision support methods. This session[1] highlights that DMDU methods must carefully represent and explore…

Is it working, and for whom? Evaluation of DMDU engagements

by Katharine J. Mach Support for decision-making on issues with large stakes, uncertainties, and differences of priorities has increasingly emphasized engagement: ongoing interactions between analysts and stakeholders. The tools supporting these engagements often incorporate advances in decision-making under deep uncertainty. Through such processes, questions are refined, goals are redefined, and…

Learning from DMDU and Complexity

By Robert Lempert Those seeking to make decisions or to exercise leadership in the world confront uncertainty because the future is not simply an extension of the past. The concept of deep uncertainty refers to situations “when parties to a decision do not know, or cannot agree on, the system…
