Using many-objective trade-off analysis to help dams promote economic development,protect the poor and enhance ecological health

Allocating water to different uses implies trading off the benefits perceived by different sectors. This paper demonstrates how visualising the trade-offs implied by the best performing water management options helps balance water use benefits and find sustainable solutions. The approach consists of linking a water resources model that can simulate many management policies and track diverse measures of system performance, to a many-objective evolutionary optimisation algorithm. This generates the set of Pareto-optimal management alternatives for several simultaneous objectives. The relative performance of these efficient management alternatives is then visualised as trade-off curves or surfaces using visual analytic plots. Visually assessing trade-offs between benefits helps select policies that achieve a decision-maker-selected balance between different metrics of system performance. We apply this approach to a multi-reservoir water resource system in Brazil's semi-arid Jaguaribe basin where current water allocation procedures favour sectors with greater political power and technical knowledge. The case study identifies promising reservoir operating policies by exploring trade-offs between economic, ecological and livelihood benefits as well as traditional hydropower generation, irrigation and water supply. Results show optimised policies can increase allocations to downstream uses while increasing median land availability for the poorest farmers by 25%.

事故灾难成因再认识——脆弱性研究

在分析比较国内外相关研究基础上,提出了脆弱性是事故灾难基本成因的观点,认为把脆弱性作为致灾主要因素有助于加深对各类灾害本质的理论认识和对实践的指导。阐述了脆弱性概念、来源和分类,进一步探讨了综合脆弱性的计算模型和评估运行模式,提出了在事故灾难应急准备工作中加强脆弱性的识别、评估和减控的建议。     

棉纺织企业火灾成因及消防管理对策研究

棉纺织企业存在大量的易燃可燃物质,火灾危险性大,极易引发火灾事故,且火灾蔓延途径多、燃烧速度快,易造成严重后果。该文根据棉纺织企业生产的特点,从人—机—环境系统的角度,从"人的不安全行为"、"物的不安全状态"和"环境的不安全条件"三个方面分析了棉纺织企业火灾的成因,有针对性从六个方面提出了消防安全管理对策,对提高企业的消防安全管理水平,增强其经济效益和社会效益具有重要的意义。     

中国民航行业可接受的安全水平研究

中国民航局提出持续安全理念,并正在制定国家航空安全方案,推动行业安全管理由目前基于规章符合性的安全监管逐渐转向规章符合性基础上的安全绩效监管,其中一项重要的工作是设定中国民航业可接受的安全水平,来衡量民航业是否满足持续改进安全的目标的要求。本文根据国际民航组织对可接受安全水平的设定指南,同时参考国外民航常用的事故指标,设计了一套中国民航行业可接受安全水平的指标体系,该指标体系包括安全评估指标、安全绩效评估指标和安全指数三层,并对该指标体系内事故率指标和事故征候率指标设定了未来10年的目标值。该指标体系及其目标值的设定不仅可作为衡量民航是否持续安全的标准,也可为航空运输企业设定自身的安全绩效考核指标提供参考。     

国外灾害风险评估模型对比分析

灾害风险评估模型是灾害风险管理的科学工具,为灾害应急管理决策提供技术支持。本文对国外几个应用较为广泛的灾害风险评估模型进行了系统总结,分析了风险评估的基本流程、方法及要点,从评估方法、应用特点、使用效果等多个角度对这些模型的优缺点进行详细的对比分析。同时,总结了灾害风险评估模型具备良好的科学性和实用性应符合的基本原则,并以本文介绍的风险评估模型为例,对其基本原则的符合性进行了对比分析。分析结果表明,灾害风险评估模型只有在科学性与实用性之间获得最佳平衡点,并与应急规划、风险管理与减灾过程充分结合才能获得最佳的应用效果;建立灾害风险评估模型尤其要重视公众充分参与、在风险相关部门和人群中通过风险沟通建立统一的认识、准确界定脆弱性人群、有效解决数学模型或专家判断的不确定性等关键问题。

Identification, analysis and dissemination of information on near misses: A case study in the construction industry

Near misses are well-known for providing a major source of useful information for safety management. They are more frequent events than accidents and their causes may potentially result in an accident under slightly different circumstances. Despite the importance of this type of feedback, there is little knowledge on the characteristics of near misses, and on the use of this information in safety management. This article proposes guidelines for identifying, analyzing and disseminating information on near misses in construction sites. In particular, it is proposed that near misses be analyzed based on four categories: (a) whether or not it was possible to track down the event; (b) the nature of each event, in terms of its physical features (e.g. falling objects); (c) whether they provided positive or negative feedback for the safety management system; and (d) risk, based on the probability and severity associated with each event. The guidelines were devised and tested while a safety management system was being developed in a healthcare building project. The monitoring of near misses was part of a safety performance measurement system. Among the main results, a dramatic increase in both the number and quality of reports stands out after the workforce was systematically encouraged to report. While in the first 4 months of the study – when the workforce was not encouraged to report – there were just 12 reports, during the subsequent 4 months – when the workforce was so encouraged – there were 110 reports, all of them being analyzed based on the four analytical categories proposed.     

地铁项目安全绩效关键影响因素分析研究

在分析研究地铁安全事故案例的基础上,识别出对地铁项目安全绩效的48个关键影响因素,将这些影响因素归为五大类,即项目参与各方对安全的影响程度、人员的不安全行为及不安全状态、材料的不安全状态、机械/设备的不安全状态和现场环境的不安全状态;采取调查问卷的方式,运用结构方程建模得出各个指标的重要度及各指标之间的相互影响。研究结果表明:"项目参与各方对安全的影响程度"和"现场环境的状态"对地铁安全绩效的贡献最大,同时,其他因素也有较强的影响,在地铁施工中应以此为重点,加强安全防范。
