讨论轨道交通系统的安全问题。在规划台湾高雄捷运红橘线时,就已考虑在整个生命周期内建立安全管理系统,符合EN50126的标准;在制定兴建运营合约时,就要求在高雄捷运红橘线兴建及运营期间必须实行安全管理,并且在合约内制定安全风险标准(包括可忍受及不可忍受的安全风险水平、执行安全管理过程所需程序等),以确保风险降为"低到合理且实际可行"的情况。重点介绍安全管理系统中的安全管理过程,包括危害辨识、危害分析、风险分析与评估、风险处理等过程,并说明高雄捷运红橘线的安全管理过程。 相似文献

工程一切险作为工程保险的最主要构成部分,对投保人顺利进行工程建设有着重要影响。目前由于投保人工程一切险索赔专业水平受限,本文将范围管理理念引入工程一切险索赔领域,从工程一切险索赔过程中的四个主要范围:保险的标的范围、保险的时间范围、保险的事件范围和保险的赔偿范围进行分析,以利于提高投保人的工程一切险索赔管理水平。 相似文献

Risk management is an inherent part of supplier selection. While companies are enjoying the benefits of outsourcing, risks brought by this practice should be taken into account in the process of decision making. This paper presents a multiobjective stochastic sequential supplier allocation model to help in supplier selection under uncertainty. Demand for products, capacities at suppliers as well as transportation and other variable costs are the main sources of uncertainty and are modeled using probability distributions. Disruptions are exogenous events and the model provides proactive mitigation strategies against disruptions by assigning backup suppliers who can be used in case of a default at a primary supplier. When there is no disruption, the model’s solution is an optimal supplier order assignment, considering operational risks. 相似文献

Road traffic accident fatalities lead to important private and social costs in the metropolitan areas of most low and middle income countries. An important share of these fatalities is due to injuries to the head and the neck. Helmets can provide efficient protection, but many drivers do not use them. We focus on helmet use behavior among motorbike users in Delhi. We use a detailed data set collected for the purpose of the study. To guide our empirical analysis, we rely on a model in which drivers decide on self-protection and self-insurance. The empirical findings suggest that risk-averse drivers are more likely to wear a helmet and that this has no systematic effect on speed. Helmet use also increases with education. Drivers who show a higher awareness of road risks seem to be both more likely to wear a helmet and to speed less. Controlling for risk awareness, we observe that drivers tend to compensate between speed and helmet use. The results can provide a basis for awareness-raising policies. They also show that improvements to the road infrastructure risk leading to risk-compensating behavior. 相似文献
