Terrorism research: should we focus on the opponent or on our own people?

In terrorism research, three different sources of information and data exist: the terrorists and their environment; the incidents; and the population. This article discusses the strengths and weaknesses of research that is concerned with, or relies on, any of the mentioned sources. An in-depth understanding of the methodological issues that come with these sources is important to correctly interpret results from scientific studies. It is highlighted how the different scientific approaches add to a holistic view of terrorism as a phenomenon. Furthermore, the double-edged sword of information in the field of terrorism is discussed. From these deliberations, guidance concerning the future work of both scholars and decision-makers can be deducted.     

云模型在雷达干扰资源多目标优化配置中的应用

鉴于干扰效果/效益评估在雷达干扰资源优化分配中的重要地位,提出了一种基于云模型和匈牙利算法的雷达干扰资源优化分配模型。利用一维云模型单条件单规则发生器和逆向云发生器构建了评估指标干扰效果推理器,利用基于风险态度因子的云模型映射函数定义了云模型之间距离的度量方法。提出了一种基于云模型与逼近理想解法的雷达干扰效益矩阵求解方法,最后运用匈牙利算法实现了干扰资源优化分配。将所建模型应用到干扰资源分配中,结果表明该模型能够较好的处理评估中的不确定性知识,是合理、可行的。     

信息化条件下空战威胁评估指标体系

目标威胁评估是空战决策研究的重要组成部分,评价指标是进行威胁评估的前提和基础。根据现代空战的特点,借鉴网络中心战思想,从空间态势、物理域、信息域、认知域4个角度,构建了信息化条件下空战目标威胁评估指标体系,并对指标体系进行了完备性、合理性、有效性检验。通过实例分析表明威胁评估指标能较好地反映信息化条件下空中目标的实际威胁,为空战决策研究提供参考。     

具有不完全信息语言多指标电子对抗计划优选方法

针对指标权重信息不完全且指标值为语言评价信息的电子对抗行动计划优选问题,给出了一种新的决策分析方法。首先建立并规范化了电子对抗行动计划的评价指标;其次给出了计划的优选步骤,其核心是通过计算理想点与计划值的距离、建立线性规划模型,确定指标权重;将语言评价信息转化为三角模糊数,相应地建立可能度,进而获得计划的综合评价值。最后通过算例分析说明了该方法的合理性和有效性。     

Performance measurement in military operations: information versus incentives

We explore the impact of strategic assessment efforts on military organizations at war. To do so, we construct a model to explore the impact of a principal’s choice among imperfect performance metrics for a military operation. In doing so, the principal must consider both the incentivizing and informational properties of the metric. We show the conditions under which uncertainty regarding the nature of the agent, as well as uncertainty regarding the operational environment, drives a metric choice that induces pathological behavior from the agent. More specifically, a poor metric choice can create an overly optimistic assessment and end up prolonging the conflict. We illustrate the model’s insights in the cases of World War II and the Vietnam War.     

图像融合的客观质量评估

随着图像融合技术在武器自动化系统中的广泛应用,图像融合的质量评估问题,即图像融合的性能评估问题,在融合方案的选择中具有重要地位。由于人工主观的图像融合评估具有很大的工程化和自动化难度,国际上研究人员都将研究目标投向了客观图像融合质量评估的研究中。从历史发展的角度系统地回顾了客观图像融合质量评估的发展历程和研究现状,对近十年来的客观图像融合质量评估方法进行了分类和分析。同时,对于国际上几种流行的图像融合质量评估方法的性能测定思路进行了介绍。对于图像融合质量评估现状的分析和讨论有助于我们对图像融合的质量评估方法进行更深入的研究。     

UN-Consistent: A Comparison of Australia's Military Interventions in Somalia and Rwanda

This article seeks to compare Australia's involvement in two key 1990s peace missions: those to Somalia in 1992–93 and Rwanda in 1994–95. While there are many similarities between the two missions in terms of time, scale and theatre, the differences are more important. Both missions are usually recalled as failures despite the Australian troops having been extremely successful in their roles during both deployments. Moreover the experiences with intervention in Africa seem to have forever blighted Australian participation in peace missions on that continent.     

基于定性信息的装备技术状态评估

利用定性信息对装备技术状态进行评估是提高评估时效性的有效手段.通过对装备技术状态评估研究现状的分析,论证了运用D-S证据理论进行装备技术状态评估的可行性.结合D-S证据理论的特点,提出了适用于装备技术状态评估的可信度分配策略.采用基于投影的证据融合方法,以解决传统D-S证据理论在融合高冲突证据时的缺陷.在评价决策中运用最大基本信度状态评价准则进行评价决策.最后,将提出的分析方法,应用于某具体装备的技术状态评估中,验证了该方法的有效性.     

有人机/无人机协同空地攻击效能评估的综合指数模型

研究了未来有人机/无人机协同空地攻击的典型作战模式,然后根据混合编队的作战过程和特点,提出了一种建立有人机/无人机协同空地攻击效能评估的综合指数模型;同时确定了综合指数模型中各分系统和分项能力的评估模型。最后以6种有人机和6种无人机的协同空地攻击效能评估为例计算并检验了模型的可用性。     

防空旅(团)战斗保障体系效能评估模型

防空旅(团)战斗保障体系的效能是形成良好防空作战能力的关键因素之一,结合防空旅(团)的实际情况,建立了防空旅(团)战斗保障体系的效能指标体系,应用AHP法(层次分析法)确立了各因素的权重,给定了防空旅(团)战斗保障体系效能的评价指标,采用模糊综合评判,建立了二级的评估模型,实现了对防空旅(团)战斗保障体系效能的量化评判模型,并通过实例分析证明了该方法的可行性。
