基于变异离散粒子群的协同空战攻击决策算法

为了提高智能协同空战攻击决策算法性能,将变异策略引入到DPSO(Discrete Particle Swarm Optimization)协同空战攻击决策算法中,提出了一种新的基于变异离散粒子群(Mutation Discrete Particle Swarm Optimization,MDPSO)的协同空战攻击决策算法。基于典型空战想定背景,仿真验证了算法的有效性。采用对比实验方法,基于准确性、可靠性和快速性等关键性能指标,分析比较了基于MDPSO协同空战攻击决策算法与多种智能决策算法,验证了基于MDPSO的协同空战攻击决策算法有着较好的综合性能。     

基于双向启发式属性约简的战术决策建模研究

从预警机指挥引导的多机协同空战原则分析出发,针对超视距协同空战决策过程中的不确定性和不完备性问题,提出了一种不完备信息系统中的基于双向启发式属性约简的战术粗决策建模方法。首先考虑粗糙集决策过程中条件属性发生缺失或不确定的情况,根据扩展不完备信息概念建立了不完备决策信息系统的最优完备选择;其次基于分辨矩阵的属性约简算法,以属性频度的大小作为启发信息进行决策信息系统约简的双向选择,得出决策信息系统的最佳约简集合;然后依据使决策最有可能发生的原则,给出决策信息系统的最优选择,以该最优选择为代表提取出决策规则;最后根据软、硬杀伤结合使用的CGF实体超视距协同空战作战想定,建立了CGF实体综合战术决策模型,并通过作战决策实例对该方法的正确性和有效性进行了验证。结果表明：该方法能在作战态势信息不完备的情况下正确给出CGF实体综合战术行为。     

基于队形相对运动带的舰艇编队规避航向优选方法

机动规避是舰艇编队避开潜艇威胁的重要措施。针对编队队形模型的特点,从舰艇编队规避潜艇于预定距离之外的角度出发,深入分析了编队队形相对运动带与规避距离关系,提出了基于队形相对运动带舰艇编队规避航向优选方法。通过战术想定实例表明,基于编队队形运动带的优选航向能够成功引导编队避开潜艇威胁,极大地简化了绘算,可为舰艇编队反潜提供一定的理论依据。

基于ANSYS的油罐拱顶稳定性分析

针对加肋拱顶稳定性十分复杂的问题,基于ANSYS建立了加肋拱顶油罐的三维有限元模型,对加肋拱顶的结构稳定性进行了数值模拟。对加肋拱顶在外压作用下的线性与非线性临界屈曲载荷进行了对比分析,利用弧长法获得了拱顶在加肋情况下径向、环向、轴向的载荷-位移曲线。结果表明:数值模拟的加肋拱顶屈曲方向和屈曲区域与实际失稳结果相一致,可以为加肋拱顶设计和稳定性分析提供一定参考。     

Do Military Expenditures Crowd-out Health Expenditures? Evidence from around the World, 2000–2013

Abstract

The paper examines the relationship between health and military expenditures using pooled cross-sectional (197 countries) and time series (2000–2013) data. Simultaneous equation models were employed to estimate the relationship between an array of public sector expenditures in order to address potential endogeneity. Our empirical findings strongly support the crowding-out hypothesis whereby increased military expenditures reduce the capacity of government to direct expenditures to health expenditures. These findings were robust to alternative specifications explored in the sensitivity analyses. Compared with upper-middle-income countries, the crowding-out effect became more pronounced among lower-middle-income countries. Consequently, this study shows that increased military expenditures negatively impacts health expenditures, and therefore poses as an important risk factor for population health and individual well-being. Moreover, it is the poorest of nations that are most sensitive to the negative effects of increased military expenditures.     

Better is the Neighbor?

Abstract

This study applies the Sequential Panel Selection Method (SPSM), to investigate the convergence properties of the military expenditure of the North Atlantic Treaty Organization (NATO) during the period of 1990–2015. Compared to the traditional methods, SPSM considers fundamentally general spatial homogeneous and heterogeneous relationships with countries and examines the evolution of military expenditure. We find that four-fifths of NATO member countries have been convergent with the UK, but no country’s military expenditure is convergent with the US. This means that there is no significant linkage effect in the US for NATO military expenditure. While they are allies of the US, the majority of NATO member countries’ military expenditures are consistent with UK military expenditure. The main reasons are due to the geographical space layout and the international relationship convergence. The results indicate that more than four-fifths of NATO member countries have been coordinated with convergence theory and spillover effect.
