基于核与灰度的区间灰数多属性群决策方法

针对属性值为区间灰数且专家权重未知、属性权重部分已知的不确定多属性群决策问题,提出了一种基于区间灰数的核和灰度的决策方法。给出了区间灰数的基于核和灰度的简化形式,充分利用区间灰数的核和灰度的信息建立优化模型求得属性的权重。在求出属性权重的基础上,运用灰色关联方法分别求取各专家的核与灰度距理想方案值的关联系数,综合两者得到专家权重,最终综合专家意见并对方案比较排序得出最优结果。鉴于此,提出一种基于区间灰数相对核与灰度的决策方法。最后以一个算例验证该方法的有效性和可行性。

基于数据适应性检验的身管磨损量预测研究

应用灰色系统理论研究不确定系统,对系统进行灰色预测模型建立的同时,需要检验系统原始数据序列是否符合建模要求。主要从3个方面检验数据建模的可行性,分别是光滑比、极比偏差和凹凸性检验。结合某型坦克炮身管内膛烧蚀磨损数据,采用不同的磨损数据作为灰色预测模型建模的原始数据序列,具体分成两种情况进行数据检验,并代入模型计算,分析不同情况下模型的预测精度,通过对比计算结果选出与模型匹配度更高的原始数据序列。     

要地防空敌袭主攻方向判断方法研究

主要对要地防空时多个可能的敌空袭兵器来袭方向进行了分析,并确定每个来袭方向的综合评价指标。应用模糊层次分析法建立多层次的评价指标体系,确立被评事物对各等级模糊子集的隶属度。应用灰色关联理论消除各个因素之间的量纲和数量级差异,将综合运算得到的量值进行排序比较,以供指挥员进行战场情况判断。     

The fertile ground of Hell’s carnival: Charles T. R. Bohannan and the US Army’s Counter Intelligence Corps’ investigations of war criminals,collaborators, and the Huk,in the Philippines 1945–1947

Insurgencies thrive in regions where government legitimacy is absent. In the post-war Philippines, Captain Charles T. R. Bohannan of the Army’s Counter Intelligence Corps became actively aware of this dynamic. Bohannan is best known for his later work with Edward Lansdale and Ramon Magsaysay in defeating the Huk Rebellion (1950–1954). Here the author examines Bohannan’s early investigative work against Japanese war criminals, wartime Filipino collaborators, and the rising threat of communist subversion most associated with the Huk. All of these experiences fed into what would be the successful campaign against the Huk, chronicled in his seminal work, Counter Guerrilla Operations: The Philippines Experience, and offers lessons on the investigative (as opposed to tactical or psychological) nature of effective counter-insurgency work, as it relates to both legitimacy in governance and the rise of insurgencies.     

从大国博弈视角解读与应对第三次抵消战略

在常规军力优势相对衰落、经费预算日益缩紧的背景下,美军为维持其军事霸权,提出了旨在实现兵力全球自由投送的第三次抵消战略(Third Offset Strategy)。通过梳理抵消战略的现实背景、历史沿革和战略目的,我们发现如果把第三次抵消战略简单视作美军的军事技术发展战略甚至军事战略,就会陷入片面而幼稚的认识误区。除了防范潜在的技术诱骗和技术突袭,更应该从大国博弈的战略视角出发,全面审视和应对第三次抵消战略对我国的挑战。美军实现国家利益的需求导向、自我变革的决心勇气和创新能力、科技兴军的先进理念和以军为主的军民融合成功经验值得借鉴。要以我为主参与制定未来战争的"游戏规则",做到"你打你的,我打我的";要深入研究美军作战体系和美国国家战略的薄弱环节,有针对性地"攻其所必救",从而化解重大安全挑战,争得新的战略机遇期。

三维均匀化理论预测多孔混凝土等效弹性模量

应用多尺度渐进展开的均匀化理论,推导三维均匀化理论的有限元解法,求解复合材料等效弹性系数。假设多孔混凝土由光滑均匀一致的球孔与水泥石基质组成,提出改进的随机投放方法,生成三维均匀化理论求解的随机单胞模型。以聚苯乙烯泡沫(EPS)混凝土为数值算例,生成6组不同体积分数的EPS混凝土随机单胞模型,通过三维均匀化理论的有限元法计算得到其等效弹性模量。计算结果表明:随机单胞模型能反映细观的非均质性,三维均匀化理论的有限元法计算得到的等效弹性模量变化趋势比较符合Miled的试验结果。     

Advancing “Defence-in-depth”: intelligence and systems dynamics

This article aims to encourage the fostering of more systems thinking, and its greater exploitation, within the domain of contemporary intelligence. With particular focus on “micro systems thinking” and with reference to key intelligence processes, such as intelligence analysis, the utility of many systems dynamics within the intelligence context seeks to be further revealed. Through their greater collective harnessing, including up to “System of Systems” (“SoS”) dynamics, and promoting all that they can offer, more sophisticated overarching operational-to-strategic/policy “ends,” notably that of “defence-in-depth,” can be viably further advanced in a sustainable manner into the future. Arguably, a much-needed transformative impact on contemporary intelligence can also be increasingly realised through comprehensively engaging in and with more systems and SoS thinking. Aiding civil protection tasks, crisis management, emergency planners, and civil contingency practitioners likewise gain.
