船舶海上应急评价初探
应急评价 综合安全评估 模糊综合评价 层次分析法
2012/7/19
尝试将综合安全评估(FSA)的原理和步骤应用到船舶海上应急管理的评价方面。依据FSA的流程,通过咨询、系统分析和向专家发调查表等方法以及不断地修改完善,构建了船舶海上应急管理评价的指标体系,运用德尔菲法(Delphi)和层次分析法(AHP)确定了各指标的权重。然后,用模糊综合评价方法建立评价数学模型,并依据评价结果,给出了提高和改善船舶整体应急能力的建议。
FMEA在乙烯罐区风险分析中的应用研究
FMEA 风险评价 不期望发生事件 潜在故障类型
2012/7/19
详细介绍国际上先进的风险管理方法故障类型和影响分析(FMEA)的评价理论和分析方法。为了能够在系统使用阶段进行故障类型和影响分析(FMEA),并缩减其工作量,对故障源分析过程进行改进,并对乙烯罐区进行FMEA风险评价。对乙烯罐区安全操作中的各种不期望发生事件,潜在的故障类型、故障因素、后果严重度、发生概率及风险等级进行逐个分析,并根据评价结果制定相应的风险削减措施。研究表明,FMEA不仅能保证系统...
欧盟民防机制经验及其借鉴
欧盟 跨区域协作 民防机制
2012/7/19
突发公共事件产生的原因往往是多方面的,发生过程也不是孤立的,其处置需要多个部门和区域的配合协调。为了应对跨区域灾难,我国政府付出了诸多努力以提高本国应急管理能力。然而,我国横向的管理碎片化问题仍然存在,大大影响了我国的应急管理效果。欧盟作为一个区域一体化组织,其民防机制涵盖多方参与者,跨国、跨区域协调功能得到国际社会的普遍认可。研究欧盟如何成功协调各国在应急管理行动中的关系将为我国有效应对跨区域灾...
经过2005年至2011年7年的煤矿资源整合,山西省煤炭行业呈现如下新的特点:矿井数目显著减少,矿井数量由原来3000多座已采煤矿减少为1000余座整合煤矿;机械化程度提高,75%以上实现机械化采煤;井型变大,升级改造基建矿井规模均达到90万吨/年以上,单独保留矿井则为30万吨/年以上;安全形势明显好转,死亡人数由400多人降为100多人;年产能由2005年6亿吨到2010年7.4亿吨;同时,由于...
