Methods and models in process safety and risk management: Past,present and future

The paper reviews past progress in the development of methods and models for process safety and risk management and highlights the present research trends; also it outlines the opinions of the authors regarding the future research direction in the field. Based on the open literature published in the leading journals in the field of safety, risk and reliability, the review covers the evolution of the methods and models developed for process safety and risk management. The methods and models are categorized as qualitative, semi-quantitative, quantitative and hybrid. The progress in the last few decades is discussed in the context of the past. Developments in the current decade formulate the basis of the present trends; future directions for research in these fields are also outlined. The aim of the article is to provide a historical development in this field with respect to the driving forces behind the development. It is expected that it will help researchers and industrial practitioners to gain a better understanding of the existing concepts. At the same time the aim is to provide direction to bridge the existing gaps through research and developments.     

Safety in shipping: the human element

INTRODUCTION: There are numerous diverse papers that have addressed issues within maritime safety; to date there has been no comprehensive review of this literature to aggregate the causal factors within accidents in shipping and surmise current knowledge. METHODS: This paper reviewed the literature on safety in three key areas: common themes of accidents, the influence of human error, and interventions to make shipping safer. The review included 20 studies of seafaring across the following areas: fatigue, stress, health, situation awareness, teamwork, decision-making, communication, automation, and safety culture. RESULTS: The review identifies the relative contributions of individual and organizational factors in shipping accidents, and also presents the methodological issues with previous research. CONCLUSIONS: The paper concludes that monitoring and modifying the human factors issues presented in this paper could contribute to maritime safety performance. IMPACT ON INDUSTRY: This review illustrates which human factors issues are prevalent in incidents therefore this gives shipping practitioners a focus for interventions.     

火灾中人员的行为及其模拟计算方法的研究

在综合分析国内外人员疏散模型和模拟软件发展现状的基础上,研究人员在火灾中的行为理论、计算机模型、模拟原理等,并介绍了目前国际上研究人员行为方面综合功能较强的Building EXODUS软件的原理和特点,最后以具体实例说明了Building EXODUS软件在人群疏散模拟分析中的具体应用.研究表明,1)在不考虑其他因素的影响下,疏散总时间与人数成正比;2)在火灾等紧急情况下,当某个出口不能通行时,可能会使大量人员在另一个出口处造成"瓶颈"现象,因此,增加备用安全出口很重要;3)疏散时间实际上是一随机变量,会因各种情况的变化而不同,如在很大程度上受人员特性(如年龄等因素)的影响,传统计算方法一般会低估疏散时间而不能作为建筑疏散设计的依据;4)利用计算机模拟软件可以对火灾中各种可能发生的情况进行评价,评价结果比传统方法更科学、可信.火灾中人员行为的研究需要从心理学和社会学角度建立人群中个人行为与社会行为的理论框架,而疏散模拟是一个由多个因素组成的复杂系统,大量人群环境的模拟需要涉及人与人、人与环境间的相互作用.

Traffic rules and traffic safety

In the present paper the effects of traffic rules on driver behaviour and on traffic safety are discussed. The discussion is mainly based on research conerning driver’s use of safety equipment, their speed adjustment and drunken driving with respect to safety potential, effects of the rules, and effects of enforcement on driver behaviour. Factors influencing drivers’ decisions to comply with rules are also considered. It is concluded that only rules that are possible to enforce should be implemented and that police surveillance should be visible to the drivers. Also, the traffic system should be seen as a social system where drivers are interacting with other drivers and road users. Rules and regulations are important to help the actors of the system to function in a safe and effective way.
