潜艇应用的C3I系统作战效能分析

为了定量分析C3I系统对潜艇作战的影响,运用了层次分析法(AHP)和模糊综合评判法对C3I系统在潜艇上应用的作战效能进行分析,结果表明,C3I系统能极大提高潜艇的作战能力,但在C3I系统的发挥重要作用的同时,指挥员的决策能力的高低是影响潜艇战斗力的关键因素。     

Petri网潜艇作战指挥效能分析

作战指挥效能系统是一个实时系统,是一个具有分布、并发、异步等特性的复杂系统.为了分析、评价和开发此类系统,依据潜艇作战指挥系统的战技指标要求,运用模糊Petri网的原理结合层次分析法,对其性能采取定性分析与定量分析相结合,以定量分析为主的方法进行评价.结果表明,这个评价模型简便可行,在军事系统效能评价中具有推广应用价值.     

潜艇作战指数计算研究

潜艇的作战指数是反映其综合作战能力的效能指标,由于传统的作战指数计算方法在实际应用中操作难度较大且横向可比性不高,提出了一种由已知的潜艇作战指数推算待求的潜艇作战指数的较为简便的新方法,即采用层次分析法确立潜艇作战能力的因素集和权重集,运用拓展的灰色关联法求得所选潜艇的灰色关联度,利用已知的作战指数和所求的关联度通过数值分析建立两者的函数关系,并由此推算出待求的作战指数.以攻击型潜艇对水面舰艇作战指数为例,求取潜艇作战指数.     

无人机保障条件下的炮兵C4ISR系统作战效能评估

针对无人机保障条件下的炮兵指挥自动化(C4ISR)系统的作战运用特点,运用模糊理论探索其作战效能评估的有效方法.综合运用模糊综合评判和层次分析法(AHP)两种决策方法对无人机保障条件下的炮兵C4ISR系统的作战效能进行了评估,评估结果表明,无人机保障条件下的炮兵C4ISR系统的作战效能水平为正常.通过对影响炮兵C4ISR系统作战效能发挥的各个因素进行定量分析比较,认为当用无人机来保障炮兵C4ISR系统时,应当把确保系统的稳定性和提高无人机与炮兵C4ISR系统之间的通信控制能力作为重要环节来抓.     

车载反坦克导弹火力分配优化模型

在车载反坦克导弹指挥控制系统软件设计过程中,火力分配模型在车载反坦克导弹射击中具有极其重要的地位作用,而传统反坦克导弹射击主要是根据攻击区进行划分,并未涉及火力分配问题,这将直接影响车载反坦克导弹作战效能的发挥.而AHP层次分析法是解决火力分配问题的有效模型,根据车载反坦克导弹的作战运用特点,并结合AHP层次分析法理论,建立了反坦克导弹火力分配的优化模型.通过对模型的求解,证明该算法对于某型车载反坦克导弹作战单元火力分配问题切实有效.     

基于AHP和模糊评价法的舰艇编队编成优化方法

海军舰艇通常以编队的形式执行各种作战任务.由于武器装备科技含量的不断提高,使得海战对抗强度日益激烈.舰艇编队作为海战的战斗单元,其作战效能的高低直接影响着海战的胜负,不同的作战任务决定了不同的编队编成.以封锁任务为作战背景,运用层次分析法(AHP)确定舰艇编队作战效能评价体系中各指标的权重,使用模糊综合评价方法对各模糊指标进行评价,评价结果表明该方法能够比较科学合理地对舰艇作战编队的编成进行优化,从而为海军舰艇作战编队编成的科学性和合理性提供了一种论证方法.

Panjwai: a tale of two COINs in Afghanistan

The US Army has two approaches to counterinsurgency operations in Afghanistan. One is hard, or combat-focused, and the other is soft, or development-focused. This study examines two US Army task forces deployed to Panjwai District, Afghanistan from 2012 to 2013. CTF 4-9 and 1-38 offer a meaningful comparison because they pursued these contrasting approaches among the same population and against the same enemy at the same time and place. The study compares each unit’s approach and finds that neither approach was successful absent the other. The article concludes by recommending further research into combining the approaches at the operational level.

Putin – the masked nemesis of the strategy of ambiguity

Recent events demonstrate the complex and adaptive approach employed by Russia to reassert influence in Europe. The changing face of Russia’s strategy commenced in 2007 when it launched a crippling cyber-attack against Estonia. This was followed by a large Russian conventional attack against Georgia in 2008, occupying two large areas of the nation. 2014 witnessed the Russian annexation of Crimea where in just a week, Russia seized control of Crimea “without firing a shot.” The annexation of Crimea was rapidly followed by a Russian inspired and led subversive war in eastern Ukraine. The common thread among these diverse Russian operations is its use of ambiguity to confound and confuse decision makers in the West.     

Forecasting a Hurricane: Israeli and American Estimations of the Khomeini Revolution

The surprising ‘Arab Spring’ raises the question as to what would enable national intelligence to provide high quality warnings prior to the eruption of popular revolutions. This article uses new sources of evidence to trace and explain Israel's success in comparison to US failure at correctly estimating the course of the Iranian Revolution in 1977–79. In explaining this variance, the article shows that it was mainly the result of the intimate acquaintance of Israel's representatives in Iran with the local language, history and culture, as well as the ability to communicate with locals – tools which the Americans completely lacked.     

关于教师继续教育培训模式的思考

继续教育作为终身教育的重要组成部分和基本形式,对教师的发展成长意义重大。继续教育工作开展十多年来,取得了一定的成绩,但还存在不少问题,如学习动机较为被动,管理认识不到位,教学内容陈旧空泛,教学方法呆板机械等。随着课程改革的不断深入,继续教育必须采取相应的改进措施,树立以人为本,服务至上的观点,教学内容的前瞻性与实用性并重,教学人员进行整合,教学方法灵活多样,评价考核规范科学等,以此激活受训教师内在的学习动机,更大程度地提高继续教育培训的实际效果。

Interpreting the Ribchester Helmet

In 1796 a 13-year-old boy playing on wasteland behind his father’s house in Ribchester, Lancashire discovered an assemblage of over 30 Roman artefacts, including a decorated brass helmet. Although partially corroded the Ribchester helmet is a fine example of a first-century AD cavalry sports helmet. This article considers how the interpretation of the helmet has evolved since its discovery. The multi-faceted iconography of the helmet with its mural crown diadem is that of an elite soldier and is paralleled in other examples of cavalry sports helmets of the Ribchester type. The long-neglected imagery on the helmet bowl is reinterpreted and seen not as a haphazard collection of randomly placed combatants but as a highly structured, symmetrical composition specifically designed to be viewed from different directions.     

Desert insurgency: lessons from the third Tuareg rebellion

This article provides an in-depth examination and analysis of the 2006–2009 Tuareg rebellion in Mali and Niger. It identifies the underlying reasons behind the rebellion, explores contrasting counter-insurgency (COIN) strategies employed by the two governments, and presents some lessons learned. While both COIN approaches ultimately produced similar peace settlements, the article argues that the Malian strategy of reconciliation combined with the selective use of force was far more effective than the Nigerien iron fist approach at limiting the size and scope of the insurgency and producing a more sustainable peace. It concludes by looking at the role of external actors, particularly the United States, and how the failure to internationalize the conflict was actually more beneficial to the local COIN effort, as well as to the longer strategic interests of the United States in the region.
