高雄捷运红橘线安全管理系统

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。

A multiobjective chance constrained programming model for supplier selection under uncertainty

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.     

Why do some motorbike riders wear a helmet and others don’t? Evidence from Delhi,India

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.     

对体系运行中假记录的探讨

国际安全管理规则（ISM）实施后,各航运公司相继实施了体系化管理,体系的建立与运行推动了各航运公司的各项管理工作,对保障船公司船舶安全与防污染起到了根本性的作用。然而,体系运行的有效性问题一直困扰着各家公司。本文分析了体系运行中＂假记录＂的产生原因、危害及治理方法,仅供同行参考。     

租约与战争风险

随着恐怖分子对美国的袭击及其后战争风险的加剧,战争风险问题已成为航运业的热门话题,船舶所有人除了要面对海上保险业中愈来愈苛刻的战争保险条款,更要面对租约中变化多端的战争条款。二战后,BIMCO推荐的各种标准战争条款(例如Voywar条款和Conwartime条款)已被广泛地采用;然而实践也表明,BIMCO标准的战争条款并不能涵盖所有的战争风险,作为船舶所有人若知道船舶将进入战区,对BIMCO标准战争条款的内容根据实际情况进行重新设计是必要的,但这要建立在对BIMCO标准战争条款仔细研究的基础上。本文将以BIMCO标准战争条款(Voywar1993和Conwartime1993)为基础,对几种常用的标准战争条款做一评析和比较。     

轨道交通引进社会资本合作项目的风险分担机制
