城区配电系统自适应鲁棒应急检修计划编排方法 [PDF]

open access: yes全球能源互联网
提出城区配电系统自适应鲁棒应急检修计划编排方法,旨在提高检修计划的灵活性和适应性,应对各种不确定性和突发事件。首先,基于“防御-攻击-防御”思想建立配电网元件检修模型。灾前防御决策人员根据有限的检修预算,考虑攻击场景,选择配电系统中的线路与电源进行检修;灾中攻击者考虑防御者能采用的优化运行策略,根据有限的攻击预算选择线路与电源进行攻击;灾后运行人员利用优化运行策略,应对攻击者所采取的攻击方案,最小化攻击造成的影响。所构建的三层两阶段自适应鲁棒优化模型基于列约束生成算法进行求解 ...

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation
