随着数字化造船技术的发展,在舰船装备研制过程中,对定量风险分析的需求越来越强烈。针对我国舰船装备系统复杂、研制周期长的特点,本文提出了一种基于全寿命周期数据管理(PLM/PDM)系统的风险管理和决策支持系统。并结合概率风险分析方法与定性风险分析方法在船舶系统应用的特点,在风险数据收集、风险模型和风险知识库建立及完善等几个方面进行了深入分析。 相似文献

舰船装备研制中的顶层设计 总被引:1,自引:0,他引:1
舰船装备的设计研究中越来越多地引入顶层设计的概念。但长期以来,在舰船装备发展过程中,对于顶层设计的内涵和任务并不十分明确。本文根据未来舰船装备体系和新型舰船装备发展的需求,分析军事需求变化与舰船装备顶层规划之间的联系,研究舰船装备总体工程和舰船装备系统工程的内在规律、彼此之间相互作用相互依赖的关系,对现代舰船装备研制过程中涉及的各方面问题进行系统工程分析,讨论舰船装备研制中顶层设计的目的、意义、基本概念和主要内容,提出舰船装备研制中的顶层设计应针对不同对象,给出了舰船装备发展战略和型号系统顶层设计的不同内容和基本过程。研究结果为在舰船研制中正确运用顶层设计提供了依据。 相似文献

舰船装备保障仍处于职能管理阶段,难以满足新形势下快速、全面、持续、精确保障等要求,实施高效合理的舰船装备保障流程管理,对减少保障资源需求、提高保障效率具有重要意义。为此,在全面分析舰船装备保障流程管理的内涵、特点与意义的基础上,将舰船装备保障流程划分为业务流程、管理流程、辅助流程3个类别和海军级、部门级、岗位级3个层次,对舰船装备保障流程建设与实施的原则和方法进行研究,提出了舰船装备保障流程再造的时机、目标和方法等,并以舰船装备保障模式由技术支援型向总体技术责任型转变为例,说明了装备保障流程再造的过程。 相似文献

引入广义梯形模糊数描述风险等级,增加了评价者的置信度指标.提出由顶点间距和重心间距相结合的综合贴近度概念,合理解决了模糊语言与模糊数的匹配关系.利用乐观指标把风险和风险报酬结合起来,建立基于双理想点的风险优属度模型,克服了传统风险度量模型只考虑风险而不考虑风险报酬的弊端.对几个舰船装备研制方案进行风险分析,MALTLAB仿真计算结果表明,风险优属度模型直接反映出了决策者自身的风险偏好程度,更加符合实际决策过程. 相似文献

Stated choice studies have been applied regularly to the valuation of time savings and other attributes of travelling as perceived by individuals. In such experiments, respondents often provide reference levels for the attributes and the hypothetical choices presented to them are pivoted around actual behaviour. However, most individuals are not able to provide reference levels for the number of casualties on the road they travel. Thus, if valuation of this important element is attempted, it is the researcher who must provide casualty risk reference levels to the respondents. Some studies have applied route choice experiments including a safety attribute but the majority has been limited to only one particular road section with a common baseline risk for all respondents. 相似文献

Environmental risk evaluation criteria 总被引:1,自引:0,他引:1
Harilaos N. Psaraftis 《WMU Journal of Maritime Affairs》2008,7(2):409-427
This paper describes an approach to incorporating environmental risk evaluation criteria within IMO’s guidelines for Formal Safety Assessment (FSA). Such criteria are currently absent from FSA, and the discussion to include them has just started. Said criteria are relevant for evaluating on a cost-benefit basis Risk Control Options (RCOs) for reducing oil spill pollution risk. Oil pollution may comefrom any ship, including bunker spills from non-tank vessels. RCOs are not necessarily ship-based, and may include vessel traffic management information systems (VTMIS) and other options. The proposed approach may be useful in extending FSA to cover environmental risk evaluation criteria and combines such criteria with criteria already in use in FSA. It can also readily be extended to environmental consequences other than oil pollution. Recent IMO developments on this matter are also reported. 相似文献

This paper presents a qualitative assessment of the risk perceptions held by key Australian stakeholder groups in the context of tollroads operated under the public-private-partnership model. The findings confirm that experience accumulated in recent years has contributed toward the betterment of risk-sharing optimisation amongst the contracting parties. The knowledge acquired through in-depth interviews supports the common view that equitable risk sharing is the vital ingredient of value for money. The proposition that the private sector is better equipped to manage commercial risks involving economic decision making whilst risks that have embedded unquantifiable social and public values and those in the domain of public governance are best left with government alone, appears to be replete with refutable implications. Public perception is a malleable concept and should be managed by both sectors. 相似文献
