تحلیل تصمیم برای مدیریت ریسک

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. In ریسک سامانه‌ای management 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 and ریسک سامانه‌ای and 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 on STEM 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 results are checked.

Analyses are checked through sensitivity analysis, peer review and stakeholder scrutiny. Retrospective review compares decisions with outcomes.

بررسیHow it is done
Sensitivity to weightsRankings are recomputed across plausible weight ranges and changes in the preferred option are reported
Value of informationThe expected value of reducing an uncertainty is estimated before commissioning further study
Requisite model reviewDecision 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.

  1. 01 Drivers

    1. 01مخاطرهDataset · Board risk committeeThe potential occurrence of a natural or human-induced physical event or trend that may harm people, property, services or ecosystems.
    2. 02مواجههDataset · Board risk committeeThe presence of people, livelihoods, species, ecosystems, infrastructure or assets in places and settings that could be adversely affected.
