考虑价格因素的并行模糊多准则时变权重云服务决策

open access: yes四川大学学报. 自然科学版, 2015
网络中云服务存储量的几何式快速增长使得云服务决策越加困难,为满足用户特殊需要并提供充足的决策依据,提出并行TOPSIS时变权重模糊云服务多准则决策算法.在并行TOPSIS改进中采用熵权重赋值形式赋予云服务相应的准则权重,使得权重的选择变得简单易行,并由此发展出时变权重提出改进TOPSIS评估机制,使用时变权重能够更好的对不同时间段的云服务质量(QoS)信息进行重要性区分,使得决策机制更加合理可信.然后基于分时模糊TOPSIS多准则决策机制,设计云服务选择的并行化融合决策框架,使得算法更趋近于工程应用 ...

Coalition Breakdown and Subsystem Exit

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Why actors choose to work together (or not) to advance policy has been the central area of inquiry within the Advocacy Coalition Framework (ACF). Existing research has mainly emphasized the pathway towards coalition formation and evolution, underscoring the stable patterns of allies and opponents observable in policy processes over a decade or

Facets of Crises: How Problem Indicators and Public Perceptions Affect Policy Change

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Crises are widely acknowledged as catalysts for policy change. Yet, our understanding of the policy effects of crises remains limited. Why do only some crises lead to major changes, while significant policy changes also occur during seemingly non‐crisis periods?

基于数据分析的变压器套管新型在线监测预警策略研究

open access: yesGaoya dianqi, 2018
套管是电力变压器的重要附件,其安全稳定运行至关重要。为此,常采用在线监测技术对其运行状态进行实时监测。在电网内部,变压器套管在线监测系统已有一定应用。然而,监测数据不仅取决于套管自身绝缘性能,而且受温度、湿度和系统运行电压等环境因素影响,且当前各套管监测厂家推荐的预警策略各异,难以满足应用要求。因此研究适宜的在线监测预警策略至关重要;文中对广东电网在运变压器套管的介损值历史监测数据进行了统计分析。研究发现变压器套管在线监测应用过程中会出现短时性、间歇性的数据异常,异常率接近1%,导致监测系统告警 ...

Regional News, Regional Bias? Evidence From Media Discourses and Welfare Decisions in Germany

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT How do media representations of immigrants shape their treatment by street‐level bureaucrats? Despite a uniform federal legal framework, decision‐making varies substantially across local welfare offices.

Mapping Measurement to Theory in Policy Evolution: A Case of Net Metering Policies of the United States

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT The examination of policy evolution has important practical implications, but current literature often only evaluates changing policy goals and instruments at the macro‐level, overlooking changes that occur at the more granular, micro‐level of policy text.

How Do Policy Narratives Evoke Emotions? An Appraisal‐Theoretic Approach

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Research on policy narratives acknowledges the crucial role that emotions play within communication and sense‐making. Especially the Narrative Policy Framework (NPF) has placed emotion at the center of attention and stressed that affect‐imbued stories are key for how individuals make sense of the world and navigate through the policy process ...
