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, EarlyView.
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

Analysis and Design of Consultancy System of Solicit Credit Consumer Evaluation [PDF]

open access: yes, 2015
在网络技术不断发展的今天,设计开发一个企业征信消费者评价咨询系统,将广大消费者对企业的信用评价纳入征信内容供全社会共享,通过消费者评价企业信用来约束企业失信,对于商业银行来说极具现实意义和研究价值。 本文论述了如何构建一个Web应用系统:企业征信消费者评价咨询系统。该系统是在共享我国信用体系建设中现有的各种类型数据库资源的基础上,设计的B/S结构系统。主要用到了XML这一关键技术,还有JSP技术等重要技术,而且运用了基于J2EE的多层体系结构以及SQLServer2005数据库 ...

Spatial identification of areas suitable for other effective area‐based conservation measures in the European Union

open access: yesConservation Biology, EarlyView.
Abstract Although significant biodiversity has been safeguarded by protected areas (PAs), biodiversity trends continue downward. Within the frameworks of the EU Biodiversity Strategy for 2030 and the new EU Restoration Regulation (2024), conserving critical biodiversity areas is essential.

Design and Implementation of Piano Playing Automatic Scoring System Based on BP Algorithm [PDF]

open access: yes, 2015
随着人们物质生活水平的不断提高,人们对精神生活的质量要求越来越高,钢琴学习也受到越来越多人的追捧。采用计算机技术对钢琴演奏技术进行自动评价,可以减轻钢琴学习负担,提高钢琴学习效果。 钢琴音乐的评价特征因素众多,评价方法模糊。根据钢琴音乐和计算机处理的特点,以及钢琴乐音自动评价的需求,选取短时平均幅度、短时平均过零率和短时平均幅度差三个钢琴乐音特征来对钢琴音乐进行评价。基于BP算法信息处理能力强,不确定性信息处理能力强等特点,采用BP算法来实现对钢琴音乐的自动评价 ...

Informal supply chains of wild meat from rural Amazonia and food security in an urban center

open access: yesConservation Biology, EarlyView.
Abstract Iquitos, the most populated city in the Peruvian Amazon, is a hub in the regional supply chain of wild meat and supplies urban consumers. Studies on wild meat consumption have focused primarily on markets, limiting the scope of species considered to those that are economically valuable and potential inferences from those data.

基于区间直觉模糊集的雷电防护能力评价

open access: yesDianci bileiqi, 2021
针对专家打分法确定指标因子权重具有较大主观性和最大隶属度原则确定评价结果存在低效和失效情况,提出基于区间直觉模糊集的雷电防护能力评价方法。依据相关国家标准和技术规范,从接闪装置、引下线、接地装置、等电位连接、电涌保护器(SPD)、屏蔽与布线六个方面构建了17个指标因子的雷电防护能力评价指标体系,并建立了基于检查检测结果确定指标因子评价语、基于区间直觉模糊熵确定指标因子权重、基于区间直觉模糊集相似度确定评价结果的雷电防护能力评价模型。以某油气集输站库为案例进行实证分析,结果表明,评价结果与实际情况较吻合 ...

A Research on the Internal Audit Performance Measurement Models Selection and Application [PDF]

open access: yes, 2016
近年来,我国企业努力提高经营效率和效益,力求将企业风险控制在低水平,而内部审计在企业这个过程中扮演着重要的角色。于是,对内部审计部门绩效制定科学有效的评价模型变得愈发重要。企业绩效评价体系应当随所处环境的变化而不断修正,就目前国内企业开展内部审计绩效评价的情况而言,大多数企业仅仅采取绩效评估表评价内部审计绩效,其绩效评价指标也很少修改。因此,如何按照企业自身情况选择内部审计绩效评价模型,讨论评价模型适应性问题成为本文研究的核心问题。 本文通过对内部审计工作进行分解 ...

物元模型在土地生态系统定量评价中的应用

open access: yesShuitu Baochi Xuebao, 2002
将土地生态系统的级别、评价土地生态系统质量优劣的指标及其特征值作为物元,对评价标准及实测数据进行归一化后,得到模型的经典域、节域、权系数及关联度,进而建立了土地生态系统定量评价的模型,并将该模型应用到石家庄市土地生态系统的评价中,与模糊评价法有较好的一致性,评价结果符合客观实际。

Research on the assessment of historic city conservation planning implementation based on fuzzy Delphi method(基于模糊德尔菲法的历史文化名城保护规划实施评价研究)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2017
我国历史文化名城保护规划实施评价的内容体系和标准体系具有双重复杂性,在实际工程评价方法上主要依赖经验判断,在评价标准上仍缺乏客观性度量及居民反馈测度,且缺乏具有可操作性的模型建构方法.需要采用合理的数理统计方法对多准则决策法进行优化,建立一套全面而简明的规划实施评价的内容体系和指标体系,为提高名城评价体系的系统性和可操作性提供思路.为此,首先建立了历史文化名城保护规划实施评价的研究思路和框架,而后基于模糊德尔菲法(FDM)分别优化了评价内容体系和评价标准体系 ...
