编队对地攻击联合火力分配问题的Swt-opt算法

根据未来战争中编队对地攻击的特点,运用一致算法(consensus algorithm)的思想对Swt-opt算法进行改进,解决关于传感器-武器-目标的联合火力分配问题。改进算法继承了Swt-opt算法解决资源分配问题在通信、计算以及对战场态势的容错能力方面的优势,克服了Swt-opt算法受限于网络拓扑结构的缺点。最后,证明了改进算法的可行性,并运用Matlab对改进算法进行了仿真实现。     

The Shi Lang,a vehicle for regional change?

In a succession of disclosures over the summer of 2011, the People's Republic of China acknowledged the near completion of its first aircraft carrier and the initiation of a carrier building program. These revelations have come at a time of increased tension in the South China Sea on top of the wider worries in the region concerning China's overly assertive stance and the pace of its military modernization. This perspective will examine why the status of the vessel and the program have now been made public, in addition to surveying the wider implications this upgrade to Chinese maritime capabilities will have on the stability of the region over the coming years. However, this paper concludes that there is, at present, no reason for the sensationalism nor the threat‐mongering seen in many media outlets, of late. Hastily drawn conclusions based primarily on realpolitik fail to understand the nuances of this issue.     

编队辐射源威胁估计研究

针对编队辐射源威胁估计结果在用途上的不同要求,以编队辐射源识别过程为依据,提出了便于编队指挥员把握战场电磁态势的宏观辐射源威胁等级划分方法,并以此为基础,利用多属性决策理论研究了微观编队辐射源威胁系数的计算方法,并以编队电子对抗中的融合识别为例给出了仿真实例。实例表明,该方法可实现编队辐射源威胁估计结果在宏观与微观使用上的统一。     

基于任务的连续出动舰载机航空保障重调度研究

对舰载机和各种保障资源进行调度是提高舰载机航空保障效率、保证舰载机所承担作战任务顺利完成的有效手段。为了克服以往研究中没有考虑作战任务变更对舰载机航空保障调度的影响,使用重调度的理论与方法研究了基于任务的连续出动舰载机航空保障重调度问题,建立了连续出动舰载机航空保障重调度模型。采用免疫算法对模型进行求解,可以避免模型的解空间可能出现组合爆炸问题。最后通过一个实例表明该模型可以很好的应对由作战任务变更所引起的重调度问起,算法求解速度满足作战需求,从而验证了模型的准确性及算法的有效性。     

编队一体化协作指挥决策概念构建

以海上编队一体化作战需求为牵引,以提升编队整体指挥决策效能为目的,在系统地分析了编队指挥决策的协同与协作的基础上,提出了编队一体化协作指挥决策的概念,并探讨了协作的一体化、指挥决策过程的一体化及元决策与指挥决策的一体化,对进一步研究编队一体化协作指挥决策过程和面向协作的辅助决策技术有着重要的参考意义。     

单一来源同类装备价格形成机制存在的问题及对策

近年来,随着国防和军队全面深化改革的深入推进和装备建设的快速发展,装备价格管理工作的重要性不断提升,但军队目前承担的装备审价任务日趋繁重,存量不减、增量日增等新情况和新问题给装备价格管理工作带来了新挑战。本文以单一来源同类装备为研究对象,借鉴《军品定价议价规则(试行)》中竞争议价和征询议价不审价的原理,从单一来源同类装备价格的形成主体、装备审价任务量、装备价格的测算方法、装备价格的形成过程以及装备价格的影响因素等五个方面分析了价格形成机制存在的问题,并从主观因素和客观因素两方面探讨了存在问题的原因,提出应在明确价格形成主体的职能权限、科学确定价格的测算方法、完善价格法律法规、建设价格数据平台、加强价格人才队伍建设等方向优化单一来源同类装备价格形成机制的对策建议。     

Damage to aircraft composite structures caused by directed energy system: A literature review

This paper presents a comprehensive review of the research studies on direct energy system effect on aircraft composite structures to develop a good understanding of state-of-the-art research and devel-opment in this area. The review begins with the application of composite materials in the aircraft structures and highlights their particular areas of application and limitations. An overview of directed energy system is given. Some of the commonly used systems in this category are discussed and the working principles of laser energy systems are described. The experimental and numerical studies re-ported regarding the aircraft composite structures subject to the effect of directed energy systems, especially the laser systems are reviewed in detail. In particularly, the general effects of laser systems and the relevant damage mechanisms against the composite structures are reported. The review draws attention to the recent research and findings in this field and is expected to guide engineers/researchers in future theoretical, numerical, and experimental studies.
