基于三角模糊数的民航企业“管理”安全综合评价模型研究

在对我国民航企业安全管理的现状和常用的安全评价方法进行分析的基础上,提出并建立了民航企业"管理"安全模糊综合评价模型。首先,从组织管理、风险管理、安全保证、安全促进4个方面对民航企业安全管理的内容和特点进行分析,在此基础上建立民航企业"管理"安全评价指标体系;然后,根据三角模糊数理论和模糊综合评价理论建立民航企业"管理"安全模糊综合评价模型;通过上述指标体系和评价模型从而达到对民航企业"管理"安全进行评价的目的。最后,给出了一个应用实例,其评价结果表明:该模型具有很强的实用性和借鉴价值。     

飞行安全的针对性评估

根据飞行员执行新的或特殊任务的需要,在研制飞行安全评估系统时,设置了针对性评估模块.运用层析分析法(AHP)确定了针对性评估模块与一般性评估模块的权重关系.根据飞行安全理论确定了一般性评估简捷方法的因素、要素及量化数据;根据层析分析法、基元事件分析法确定了针对性评估模块的结构和因素的权重,采用基元事件分析法、飞行法规分析和调查研究相结合的方法,对针对性评估的要素进行了量化.最后针对具体事例做了评估计算.研究表明,当针对性评估的安全度小于90%时,应引起足够的警觉,采取必要的措施.     

危险品道路运输泄漏引发水污染事故的定量风险评估方法研究

介绍了由道路交通事故引发的地表水污染事故风险定量分析方法,重点分析了突发水污染事故源发生概率和危害后果表征方法.以评价水域内道路危险品运输泄漏事故发生概率为水污染事故源发生概率.污染事故后果危害水平的表征:1)敏感区(点)最高浓度; 2)敏感区(点)超标总历时;3)水质超标的范围(如超标河流长度).评估方法为陆源造成的突发水污染事故的预防管理与应急计划的制订实施提供了科学依据.     

Environmental evaluation for workplace violence in healthcare and social services

PROBLEM: Federal policy recommends environmental strategies as part of a comprehensive workplace violence program in healthcare and social services. The purpose of this project was to contribute specific, evidence-based guidance to the healthcare and social services employer communities regarding the use of environmental design to prevent violence. METHOD: A retrospective record review was conducted of environmental evaluations that were performed by an architect in two Participatory Action Research (PAR) projects for workplace violence prevention in 2000 and, in the second project in 2005. Ten facility environmental evaluation reports along with staff focus group reports from these facilities were analyzed to categorize environmental risk factors for Type II workplace violence. RESULTS: Findings were grouped according to their impact on access control, the ability to observe patients (natural surveillance), patient and worker safety (territoriality), and activity support. DISCUSSION: The environmental assessment findings reveal design and security issues that, if corrected, would improve safety and security of staff, patients, and visitors and reduce fear and unpredictability. IMPACT ON INDUSTRY: Healthcare and social assistance employers can improve the effectiveness of violence prevention efforts by including an environmental assessment with complementary hazard controls.     

Carbon capture and storage-desirability from a risk management point of view

Environmental and safety risks related to carbon capture and storage concern leakages and accidental releases during transport and geological storage. Based on principles widely accepted in the EU and beyond in the discussion about the where’s and why’s of nuclear waste repositories, this paper discusses the desirability of carbon capture and storage from a risk management point of view, focusing on environmental risks on the global level (climate change). On this basis it is concluded that, if the key energy issue of coming generations, not just in Europe but all around the world, is not the abundance of fossil resources but rather an unacceptably high probability of global warming due to greenhouse gas emissions, then the solution should not include any massive hiding of the emissions but entirely focus on the avoidance based on improved technology in power plants and other industrial installations.
