网络中心作战体系效能评估方法初探

网络中心作战体系是信息化战争要求下的一个具体作战体系,其效能评估是网络中心战研究领域的重要问题,是解决网络中心作战体系建设中方案论证、性能效能指标、经济因素等诸多问题的有效方法。首先提出了网络中心作战体系效能评估的基本概念;然后阐述了网络中心作战体系效能评估方法问题,分析介绍了几种较为成熟的评估方法的特点、适用性和不足;最后提出一种基于探索性建模与分析方法的网络中心作战体系效能评估框架,作为研究网络中心作战体系效能评估的参考评估框架。     

Property distribution and configurations of sovereign states: A rational economic model

A nation's wealth is both an object of conquest to covetous aggressors and a resource to its owners for self defense. To maintain autonomy every country must mount a defense which either makes its capture (1) more expensive than any aggressor can afford, or (2) more expensive than it is worth to aggressors. Whether this condition can be satisfied for all countries simultaneously depends as shown in this paper on relative efficacy of military offense versus defense, the aggregate of wealth among nations and its distribution, and the benefits a conqueror may obtain from conquest, including the duration of these benefits. The paper shows how these factors fit together to determine the sustainability and stability of the international distribution of property as embodied in the configuration of sovereign states.     

基于模糊综合决策的航迹相关算法

引用模糊综合决策的思想,提出一种新的分布式航迹相关算法．文中论述了多因素模糊综合评判的基本模型,详细讨论了合成运算模型的选择,重点研究了模糊综合航迹关联准则,并通过仿真将它与两种经典方法进行了比较．仿真结果表明,在密集目标环境下和／或交叉、分岔及机动航迹较多的场合,模糊航迹关联算法的性能明显优于传统方法,其正确关联率比传统方法提高了大约35％．     

基于SNA的指挥控制关系及其中心性分析

社会网络分析方法(Social Network Analysis,以下简称SNA)是指挥控制关系研究领域新近引入的一种有效的定量分析方法.从社会学的角度分析了指挥控制关系网络中权力的"影响"和"支配"两个维度,研究了C2组织中的指挥控制权力和指挥控制关系.结合一个想定,从点度中心性和中间中心性两个方面介绍了指挥控制关系中心性研究的基本思路,并且借助于社会网络分析应用软件,对想定中的C2组织进行了中心性的实际计算和分析,得出的结论对于C2组织及指挥控制关系的设计和建模仿真具有重要意义.

Influence of Al2O3 particles on the microstructure and mechanical properties of copper surface composites fabricated by friction stir processing

The influence of three factors, such as volume percentage of reinforcement particles (i.e. Al₂O₃), tool tilt angle and concave angle of shoulder, on the mechanical properties of Cu–Al₂O₃ surface composites fabricated via friction stir processing was studied. Taguchi method was used to optimize these factors for maximizing the mechanical properties of surface composites. The fabricated surface composites were examined by optical microscope for dispersion of reinforcement particles. It was found that Al₂O₃ particles are uniformly dispersed in the stir zone. The tensile properties of the surface composites increased with the increase in the volume percentage of the Al₂O₃ reinforcement particles. This is due to the addition of the reinforcement particles which increases the temperature of recrystallization by pinning the grain boundaries of the copper matrix and blocking the movement of the dislocations. The observed mechanical properties are correlated with microstructure and fracture features.     

一种航天侦察任务的关联度分析与去冗余方法

针对航天侦察需求响应中可能存在的任务重复产生问题,综合考虑任务的需求来源、质量要求、时间偏好及空间范围,提出一种基于任务关联度的任务冗余分析方法。首先,对航天侦察的相关要素进行分析度量,给出了基于四类要素的任务关联度计算方法,然后提出了通过任务之间的关联度来降低可替代任务产生概率的具体算法,进一步考虑了准确优先、公平优先以及混合等不同情况下的冗余度计算方法,最后,给出一个应用示例,说明所述分析方法的有效性。研究结果表明,该方法具有良好通用性,可为航天侦察任务的预处理提供有效支持。     

Institutional Analysis and Irregular Warfare: A Case Study of the French Army in Algeria 1954–1960

This article proposes a case study to illustrate the usefulness of sociological institutional analysis as a method to uncover ‘blue force’ challenges to deal with irregular warfare. The French Army's adaptation to revolutionary warfare in Algeria, starting in 1954, is used to illustrate both the application of the methodology and how institutional forces can hinder as well as overwhelm transformation for irregular warfare. The analysis emphasizes three key dimensions of the French Army's institutional adaptation: the regulative, normative and cognitive. These empirical elements are used to show how they interacted and influenced the institutional implementation of the French COIN structures.
