空天环境对作战效能的影响——基于云模型的评估方法

空天环境作为传统战场空间的拓展,是打赢信息化战争、维护国家安全的重要战略高点。为更好了解空天环境对作战效能的影响,运用云模型的评估方法,从自然环境、作战平台、武器装备等方面对空天环境进行研究,以期对空天作战发展方向提供参考。研究表明,应根据空天作战时自然环境对作战的影响权重,增强空天作战平台与新概念武器自主适应环境的能力。     

基于BP神经网络的UCAV航迹综合评价

针对目前航迹规划过程中评价指标难以统一且指标权重确定过分依赖主观经验的问题,在建立较为完备的UCAV航迹评价指标体系基础上,引入BP神经网络对UCAV备选航迹进行综合评价,从备选航迹的样本数据出发,客观分析航迹的优劣,为决策者提供更加科学合理的参考依据,最后结合仿真算例,验证了该方法的可行性。     

联合作战战场态势一致性评估

本文从战场态势一致性的影响因素出发,分析给出了动态目标一致性评估指标体系,并从作战需求和指标关系分析入手,采用效用函数和综合赋权相结合的方法对战场态势一致性进行了评估。经仿真验证该评估方法合理可行,对联合作战战场态势一致性的评估具有指导意义。     

技术成熟度多维评估模型研究

技术成熟度直接关系到武器装备的研制和应用。针对技术成熟度评估存在过度依赖专家智慧、操作周期长、费用高;指标单一、可信度缺乏;数据难以获取、评价方法难度较大等问题,研究了技术发展与技术对应文献关系,提出了基于技术分解结构构建技术成熟度多维评估模型,分析了基于S曲线知识图谱划分技术成熟度等级,并以航母电磁弹射器技术为例进行模型验证。研究表明,技术成熟度多维评估模型具有客观、简便、费用低、易操作等特点,可以与TRL互为补充。     

基于复杂性的战场损伤定位流程评价模型研究

损伤定位流程制定的合理与否是衡量一个评估员水平高低的重要指标之一。对损伤定位流程的评价涉及到所用时间、工具、操作的难度等指标都可以用其复杂性来表示,目前鲜有关于损伤定位流程评价的研究,因此提出战场损伤定位流程的复杂性,并借鉴软件工程领域的程序复杂性量化方法——图熵法对其进行量化。经过数据验证,复杂性与评估时间之间存在较好的拟合关系,并用实例说明了模型的应用效果。     

Portfolio analysis for defense: taking account of networking

To manage their assets at an enterprise level, defense organizations have turned to portfolio theory for the planning, analysis and management of their military forces and materiel. Despite being well established in the commercial sector, the application of portfolio approaches in defense is problematic. The vexatious question for defense of how to define and measure benefits arising is complicated by the increased utility and effectiveness achieved through networking of military forces and the equipment they use. The authors discuss the challenges for defense in using a portfolio approach and propose a conceptual model for dealing with the effects arising from networking with information and communications technologies.     

Linking a throughput simulation to a systems dynamics simulation to assess the utility of a US Navy foreign humanitarian aid mission

The success of any humanitarian aid mission is generally measured by the timeliness of critical supplies that are delivered to the affected area. However, a more interesting analysis may be to determine the effect of the aid on the overall satisfaction of the local population. The authors' research focused on the delivery of humanitarian aid to a notional region that was decimated by flooding with ships, landing craft and security personnel provided by the US Navy and Marines. While the research effort addressed naval force structure, the focus of the research was: (1) to assess different delivery methods for the aid; and (2) to determine how the aid delivery impacted the overall satisfaction of the local population. To examine both concerns, two simulation models were developed, with one examining the throughput of aid delivered during the operation, and the other the satisfaction of the population based on the humanitarian aid effort.     

海上远程精确打击体系作战能力评估指标空间建模方法研究

现代战争的信息化程度、复杂性和不确定性不断提高,对海上远程精确打击（LPSS）体系作战能力的评估提出了更高的要求．要想准确评估系统的作战能力,建立合理的LPSS体系作战能力评估指标体系非常关键．然而影响LPSS体系作战能力的指标繁多,指标间存在冗余和相关性,不同层次指标间还存在交叉性,直接采用这些指标会增加后续评估的时空复杂度．在创建LPSS体系作战能力评估指标体系的基础上,对评估指标空间的建模方法进行研究,创建了可供评估的数据样本空间,为后续对底层指标集合进行约简、降维处理奠定了基础．     

舰炮对海上集群小目标射击的毁伤概率

海上集群小目标是水面舰艇面临的主要威胁之一。以单管大口径舰炮对海上集群小目标射击作为研究对象,对集群目标进行了等效处理,分析了弹种、引信和装药的选择以及效力射中的表尺分配问题,提出多表尺效力射方法,利用该方法对海上集群小目标射击的毁伤概率进行了分析。结果表明,采用该方法并使用空炸榴弹或杀伤爆破弹,可有效破坏敌运输工具,杀伤其有生力量。     

The Practice and Power of Firing Broadsides in British Men of War During the Age of Fighting Sail

The development of naval broadside tactics and practice is discussed. The technology of smooth bore ordnance is examined, with an account of naval gunfiring trials. The fundamental purpose of gunnery at sea — damage to ship structure and casualties sufficient to disable an enemy ship — is reviewed.
