非常规突发事件下,应急通信是实施指挥调度和保障信息传递的关键,其重要的前提和基础是应急通信预案体系的合理、有效。基于此,参考国内外相关标准,提取评价指标,运用网络分析法确定指标权重,通过模糊综合评价(FCE)的方法对应急通信预案的实施效果进行评估,从而建立评估体系,为我国应急通信预案有效性的评价提供有益借鉴。 相似文献

为准确评估核电厂场内应急预案,提出一种基于犹豫模糊语言集(HFLTS)的评估方法。首先从预案内容的角度出发,基于组织机构及职责、应急准备、应急响应与防护、应急保障以及总结与后期处置五个维度构建核电厂场内应急预案评估指标体系;其次考虑到群决策过程中专家给出评价时的犹豫性,运用HFLTS-层次分析法(AHP)计算指标权重,并利用犹豫模糊加权平均算子(HFWA)确定综合评分;最后以大亚湾核电站为研究对象,分析其场内应急预案的关键内容和不足之处,验证该评估方法的有效性和可靠性。研究结果可为今后完善核电厂场内应急预案提供参考借鉴。 相似文献

应急预案的构建是图书馆危机管理的重要组成部分。针对我国高校图书馆应急预案普遍零碎、表面化以及缺乏体系的现状,提出图书馆应急预案的制定应该遵循"以人为本、预防为主,危机分级、重点突出,信息公开、权责分明"的原则,其内容设置则从危机管理所要求的预防、准备、响应和恢复4个环节进行构建,考核评估工作相应地选取"应急预防、应急准备、应急响应、应急恢复"4个一级指标,进而细化。最后指出人始终是应急预案中第一要素,要重视实践。优秀的应急预案需要定期演练,从实践中总结经验教训,从而不断优化预案。 相似文献

When public events occur, users often generate a huge number of microblog entries and their online interactions with one another. Forwarding and commenting on posts contribute to the huge networks of topic and sentiment communication. This study constructs the topic and sentiment propagation maps of microblogging in the context of public events to visually explore the patterns of topic and sentiment propagation among stakeholders across different phases. To quantify the influence of topic and sentiment propagation, four indicators of “topic out-degree,” “topic variation degree,” “sentiment out-degree,” and “sentiment deviation degree” are proposed. We chose the child abuse case in the Beijing Red-Yellow-Blue (RYB) Kindergarten for our study. The positions of various stakeholders in the propagation paths and the relationship among stakeholders were revealed. Results indicate that the government and mainstream media have the greatest influence in terms of topic and sentiment propagation. Moreover, topic propagation was the most influential in the recession phase and the same can be said with sentiment propagation in the spreading phase. The findings can help the emergency management departments gain a better understanding of the propagation patterns of topics and emotions and the role of stakeholders in such phenomena to improve their emergency response ability. 相似文献

“We the Media” networks are real time and open, and such networks lack a gatekeeper system. As netizens’ comments on emergency events are disseminated, negative public opinion topics and confrontations concerning those events also spread widely on “We the Media” networks. Gradually, this phenomenon has attracted scholarly attention, and all social circles attach importance to the phenomenon as well. In existing topic detection studies, a topic is mainly defined as an "event" from the perspective of news-media information flow, but in the “We the Media” era, there are often many different views or topics surrounding a specific public opinion event. In this paper, a study on the detection of public opinion topics in “We the Media” networks is presented, starting with the characteristics of the elements found in public opinions on “We the Media” networks; such public opinions are multidimensional, multilayered and possess multiple attributes. By categorizing the elements’ attributes using social psychology and system science categories as references, we build a multidimensional network model oriented toward the topology of public opinions on “We the Media” networks. Based on the real process by which multiple topics concerning the same event are generated and disseminated, we designed a topic detection algorithm that works on these multidimensional public opinion networks. As a case study, the “Explosion in Tianjin Port on August 12, 2015″ accident was selected to conduct empirical analyses on the algorithm's effectiveness. The theoretical and empirical research findings of this paper are summarized along the following three aspects. 1. The multidimensional network model can be used to effectively characterize the communication characteristics of multiple topics on “We the Media” networks, and it provided the modeling ideas for the present paper and for other related studies on “We the Media” public opinion networks. 2. Using the multidimensional topic detection algorithm, 70% of the public opinion topics concerning the case study event were effectively detected, which shows that the algorithm is effective at detecting topics from the information flow on “We the Media” networks. 3. By defining the psychological scores of single and paired Chinese keywords in public opinion information, the topic detection algorithm can also be used to judge the sentiment tendencies of each topic, which can facilitate a timely understanding of public opinion and reveal negative topics under discussion on “We the Media” networks. 相似文献

石油企业HSE管理体系运行中存在着领导重视不够、缺乏总体运行计划、与日常管理脱节、风险识别和评价水平低、作业指导文件针对性不强、应急预案操作性不强、监督考核h度不够等问题,提出解决这些问题要加强领导和员工的培训、将HSE管理纳入企业总体年度计划并把日常的规定和办法融入体系运行管理、要用科学的方法全员参与风险的识别和评价、要结合实际编制作业指导文件和应急预案并不断完善和修订、要把体系运行和经济处罚挂钩以考核促进体系深入运行等对策。 相似文献
