Robust decision making
Candidate policies are run across a large ensemble of futures; the conditions under which each fails are identified and used to design options that are less vulnerable.
GRF · Foresight Nexus
Decision analysis under uncertainty links foresight to choice. It makes objectives, options, uncertainties and value judgements explicit, and under deep uncertainty it replaces the search for an optimal answer with tests of robustness and adaptability across many futures.
Decision analysis under uncertainty provides structured methods for choosing among options when outcomes are uncertain and objectives conflict. It makes trade-offs and value judgements explicit. In foresight and risk management and xetera pergalî, decision analysis helps choose actions that perform acceptably across interconnected risks and uncertain futures. It clarifies when to act now and when to keep options open. The canonical description is on the STEM Commons.
Candidate policies are run across a large ensemble of futures; the conditions under which each fails are identified and used to design options that are less vulnerable.
Sequences of actions are mapped with their adaptation tipping points and lead times, so decision-holders can see which choices keep later options open and when a switch falls due.
Experts are selected, briefed and asked for quantiles on uncertain quantities through Delphi rounds or calibrated protocols; judgements are aggregated and their spread is reported rather than hidden.

Li seranserê şeş stûnan, bi pêşengiya Nexus Consortium
Analyses are checked through sensitivity analysis, peer review and stakeholder scrutiny. Retrospective review compares decisions with outcomes.
| Kontrol bikin | How it is done |
|---|---|
| Sensitivity to values | Results are re-run with alternative weights and discount rates and the effect is reported |
| Expert calibration | Where possible, experts answer seed questions with known answers to weight or check their judgements |
| Scenario sampling adequacy | The ensemble is checked for coverage so robustness is not claimed over a narrow set of futures |
| Traceability | Each result traces to stated objectives, options and assumptions that reviewers can examine |
Results depend on elicited probabilities and preferences that may be biased. Deep uncertainty can make expected value comparisons misleading.
