基于GO法的多阶段共因失效任务系统可靠性评估

为了解决部件阶段依赖性与共因失效给系统可靠性分析带来的复杂性,针对多阶段共因失效任务系统,结合GO法易于处理有时序、含共因失效系统可靠性分析的特点,首先,将前一阶段的输出信号作为后一阶段的输入信号,建模时首尾连接各阶段模型,建立整个任务系统的隐性GO模型;其次,在进行各信号流状态组合运算时,融入阶段代数处理部件的阶段依赖性;再次,用隐性共因失效分析,将共因失效对系统的影响在状态组合的定量分析中表达出来,得到所需系统可靠性指标;最后,与基于二元决策图的算法进行对比验证。结果表明:GO法可以简捷、准确地处理多阶段共因失效任务系统可靠性评估问题。

An application of the MTP2 property on bounds on system reliability

This paper is concerned with the joint prior distribution of the dependent reliabilities of the components of a binary system. When this distribution is MTP₂ (Multivariate Totally Positive of Order 2), it is shown in general that this actually makes the machinery of Natvig and Eide [7] available to arrive at the posterior distribution of the system's reliability, based on data both at the component and system level. As an illustration in a common environmental stress case, the joint prior distribution of the reliabilities is shown to have the MTP₂ property. We also show, similarly to Gåsemyr and Natvig [3], for the case of independent components given component reliabilities how this joint prior distribution may be based on the combination of expert opinions. A specific system is finally treated numerically. © 1997 John Wiley & Sons, Inc. Naval Research Logistics 44: 741–755, 1997

美军“作战信息中心”的概念、内涵及启示

自20世纪中叶,美军舰载指挥控制系统中频繁出现一个词“CIC（ Combat Information Center）”,由此,CIC作为舰艇中枢神经,几乎成为美军各型舰艇的标准配置。国内很多技术人员和参考书籍将CIC翻译成“作战情报中心”,这容易引起很多误解。注意CIC用词“Information”,不是“Intelligence”,一词之差、谬之千里,应该译为“作战信息中心”。侧重于对CIC的内涵进行剖析,试图揭示其内在的发展规律。 CIC的演化过程中蕴涵着美军在装备发展过程中的各种试错、实践、经验和教训,美军装备建设的严谨、求实和科学的成份,特别是其技术进步的持续性和连贯性,值得借鉴和思考。     

Beyond Just War: Military Strategy for the Common Good

The objective of this article is to move ethical discourse on military strategy beyond the confines of the established War Convention. This is achieved by utilising the common good, a concept found in political philosophy and theology. The common good acts as a positive organising concept for socio-political activity. With its focus on peace, development and the flourishing of the individual and community, the common good poses a significant challenge to strategy. This article constructs an approach to strategy that is compatible with the common good. Importantly, it does so whilst respecting the pursuit of victory as an indispensable component of strategy’s true nature. The theory presented in this article is then tested in relation to four different modes of strategy: regular war, irregular war, deterrence, and cyberwar.     

军用柴油机高压共轨系统共轨管设计与仿真

结合大功率柴油机配机要求,进行了高压共轨喷油系统共轨管结构设计研究。针对某型军用柴油机结构和共轨管结构特点,提出适合的柴油机高压共轨系统方案,确定了双轨结构型式的共轨管,计算了不同共轨管的结构参数。通过建立双共轨管的简化仿真模型,分析双轨结构不同参数的共轨管压力波动变化,提出了双共轨管参数方案,结果表明该方法能获得较合理的双共轨管参数。
