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。     

SVM在空中目标威胁值评估中的应用

构建了基于回归型支持向量机的空中目标威胁值评估模型,确定了基于粗糙集理论的空中目标威胁因素,并建立了数据离散化、归一化的标准。将常用的4种核函数应用于对空中目标威胁值的估计,并通过基于网格法和遗传算法的搜索方法找到模型的最优参数。最后通过Matlab对算例进行了仿真验证。     

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。     

直升机载制导火箭弹命中精度评定研究

针对直升机载制导火箭弹特点,根据命中精度概念,分析出直升机载制导火箭命中精度的合理表示方法;考虑研制成本、试验条件等因素,提出研制阶段基于点估计和区间估计的制导火箭命中精度评定方案,并通过试验数据验证其正确性。鉴于产品批量生产交付阶段抽检质量时实弹难以统计弹着点和用弹数量有限的困难,提出了CEP评定转换为命中率考核,采用截尾序贯法,并进行优化的评定方案。     

装备合同履行管理的动态演化博弈研究

在装备合同履行中存在着明显的信息不对称现象。为提高装备合同的履行效益,减少信息不对称的影响,在有限理性假设的前提下,建立了装备合同履行监督的动态演化博弈模型。对合同履行过程中承制单位与军事代表、合同履行管理部门之间的博弈关系进行了探究,得到了各参与方在不同条件下均衡策略的选择,并对优化装备合同的履行管理提出了建议。     

Remotely Piloted Aircraft,Risk, and Killing as Sacrifice: The Cost of Remote Warfare

In this paper I argue that a remotely piloted aircraft (RPA) pilot’s act of killing remotely, when it is done in the defense of another person, can be viewed as an act of sacrifice. This argument concludes from two premises. First, the RPA pilot faces psychological risk to self by carrying out such an action; second, the RPA pilot is motivated to some significant degree by something other than self-interest. Moreover, I challenge both the view that RPA represent merely an incremental development in technology yielding an incremental expansion of the distance between the war-fighter and the target and the view that RPA is revolutionary in some fundamental sense. I instead argue that, based upon the natural geometric boundary imposed by the earth’s shape, RPA have maximized the physical distance between the war-fighter and the target and, over time, this fact will change, not only the psychological effects on the RPA pilot, but also the way we view killing and distance in general. When taken together, these two broad claims, that other-defense can justify killing in war and that there is a psychological cost paid by remote killers, yield a conception of remote killing as an act of sacrifice that will inform the broader conversation about ethics, risk, killing, and RPA.     

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。     

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.
