前瞻中的决策分析

Decision analysis under uncertainty links foresight to choice. It makes objectives, options, uncertainties and value judgements explicit, and under 深度不确定性 it replaces the search for an optimal answer with tests of robustness and adaptability across many futures.

不确定性下的决策分析在此处的作用。

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 系统性风险, 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.

稳健决策

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.

Dynamic adaptive policy pathways

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.

Structured expert elicitation

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.

结果如何核查。

分析通过 敏感性分析、同行评审与利益相关方审视加以核查。回顾性审查将决策与结果进行比较。

核查如何开展
Sensitivity to valuesResults are re-run with alternative weights and discount rates and the effect is reported
Expert calibrationWhere possible, experts answer seed questions with known answers to weight or check their judgements
Scenario sampling adequacyThe ensemble is checked for coverage so robustness is not claimed over a narrow set of futures
TraceabilityEach result traces to stated objectives, options and assumptions that reviewers can examine

结果取决于征询得到的概率与偏好,而这些可能存在偏倚。深度不确定性可能使期望值比较产生误导。
