Decision analysis structures choices under uncertainty: it makes the options, objectives, uncertainties and trade-offs explicit so that a decision can be examined and defended. Inمەترسیی سیستەمییmanagement it supports appetite setting, the choice of treatments and the selection of investments in resilience where consequences are uncertain and values conflict.
What decision analysis under uncertainty does here.
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 risk management andمەترسیی سیستەمییand methods and modelling, 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 onSTEM Commons.
Multi-criteria treatment choice
Options for treating a risk are scored against objectives such as safety, cost, service continuity and equity, with weights elicited from decision makers and the sensitivity of the ranking to those weights reported.
Decision trees for contingent plans
Sequential choices, such as whether to invest now or wait for information, are laid out with their probabilities and consequences, and the value of further information is estimated before commissioning it.
Robust choices across scenarios
Strategies are tested across many plausible futures to find those that perform acceptably in most of them, and the conditions under which each strategy fails are identified.

How it is done
Sensitivity to weights
Rankings are recomputed across plausible weight ranges and changes in the preferred option are reported
Value of information
The expected value of reducing an uncertainty is estimated before commissioning further study
Requisite model review
Decision makers confirm that the model captures the objectives and options they consider relevant
Results depend on elicited probabilities and preferences that may be biased. Deep uncertainty can make expected value comparisons misleading.

Decision analysis for risk management: Hazard, exposure, vulnerability
In IPCC AR6 Working Group II, climate risk results from interactions between hazards and a system’s exposure and vulnerability, and responses can add risk.
01 Drivers

What are the limits of decision analysis under uncertainty in this field?
Results depend on elicited probabilities and preferences that may be biased. Deep uncertainty can make expected value comparisons misleading.
How are results checked?
Analyses are checked through sensitivity analysis, peer review and stakeholder scrutiny. Retrospective review compares decisions with outcomes.
Are the values on this page real?
The data names, roles and checks are real descriptions of practice. The canvas shows a design of the method’s use, not a run; no result is reported here.
