一种通用型舰载防空硬武器火力优化算法?

针对当前武器优化分配算法缺少通用性,难以兼顾效率和时间的问题,提出了一种通用型舰载防空硬武器火力优化算法。该算法首先提取各舰载武器能够攻击的目标集合,然后对各武器的目标集合逐一进行时间分配,并计算对目标的毁伤概率,最终完成所有武器的分配。计算表明,该算法具有很好的通用性和实时性,可适用于较大规模舰载防空硬武器的火力优化分配问题。

Challenges of institutional coordination in complex defense acquisition programs: the case of the Republic of Korea’s F-X program

Decision-making in defense acquisition programs in the Republic of Korea (ROK) has been problematic, especially in highly advanced complex systems. The highly disputed force modernization program for the ROK Air Force’s fifth-generation fighter, dubbed the Fighter eXperiment, went through extreme turbulence during the type selection phase. The gist of the turbulence became evident through poor institutional coordination within the defense acquisition authorities that eventually forced them to rescind the decision generated from their own yearlong efforts, thus basically shooting themselves on the foot. The paper highlights the background of the program and reviews the institutional elements that influenced the decision-making process, and conclude that the absence of an effective coordination mechanism has made decision-making in complex defense programs even more troublesome.     

Defense policy in Brazil: bridging the gap between ends and means?

This article aims to analyze the Brazilian Defense Policy in terms of its ability to reduce the gap between ends and means. Since 2003, the Brazilian defense policy has evolved along with Brazil’s increased role in the international system. Sustaining this process depends on institutional, economic, and operational conditions that are yet to be fully guaranteed. They require negotiations, reforms, and strategic perspective. By identifying specific challenges emerging from the national security institutional framework, the combat capability building process, the budgetary cycle, as well as from the defense industrial base, we sought to explain their rationale and to offer concrete policy pointers to overcome obstacles. As a general conclusion, the Brazilian defense policy was strengthened by the 2008 National Defense Strategy (END) due to its clearer strategic goals. Bridging the gap between those ends and the proper means is a continuous effort for any given country, but in the case of Brazil it has been addressed with firmer steps since the END, even in the face of harder economic and political conditions.     

特种作战力量网络空间防御作战效能评估方法?

根据特种作战力量网络空间防御作战系统的结构模型的预警、保护、检测、响应和恢复五个方面,按照指标的不同类型和特点,利用模糊综合评判法对指标进行量化、一致化和标准化处理,利用层次分析法确定各指标的权值,最后利用综合加权法建立综合效能评估模型从而实现对网络空间防御作战的效能评估。该方法适用性和实用性强,为网络空间防御作战效能的评估提供一种方法和思路。     

基于支持向量机的多目标分类和识别

支持向量机(SVM)算法广泛应用于模式识别等领域,但是SVM最初是针对二类别分类提出,在多分类识别中稍显逊色。对将SVM由二分类扩展到多分类的算法进行了研究,发现有向无环图(DAG-SVM)是其中用的最多的算法之一。因此,针对军事领域图像的多目标分类,选择有向无环图算法来实现军事图像中单兵、装甲、低空等多目标的分类识别。

返回器飞行管道的快速预测算法

针对返回器回收任务中对安全空域和期望落点的计算需求,提出了基于Koopman算子的飞行管道快速预测算法,给出了搜救直升机安全飞行空域的判定流程。建立了物伞动力学模型,利用Halton采样方法从随机空间中均匀采点,计算得到多条可能弹道;采用Koopman算子的后拉机制,将初始概率密度值与当前状态关联,得到不确定条件下返回器及其分离部件的飞行管道和期望弹道。仿真结果表明,基于Koopman算子的飞行管道快速预测算法在收敛速度和精度上都要显著优于Monte Carlo方法;利用飞行管道计算结果对搜救直升机飞行路线进行规划后,碰撞风险最大降低54%且搜索时间减少70%。飞行管道预测算法已成功应用到嫦娥五号的回收任务中。
