Reforming China’s defense industry

ABSTRACT

Even with sizable economic inputs, access to foreign technologies, and considerable political will, China, up until the late 1990s, experienced only limited success when it came to the local design, development, and manufacture of advanced conventional weapons. Not surprisingly, therefore, reforming the local defense industry in order to upgrade its technology base and manufacturing capabilities and to make armaments production more efficient and cost-effective has long preoccupied the Chinese leadership. The fact that most of these efforts had little positive impact on the country’s military technological and industrial capabilities only encouraged Beijing to experiment with additional reforms in the hopes of finally getting it right.     

指定目标不延误条件下的拦截决策算法

从现有的拦截排序准则出发,根据实际作战中进袭目标的特点,应用现代排序理论,分别建立了动态目标拦截排序模型和总损失最小化模型,给出相应的求解算法。最后实例计算得出模型既体现了现有的拦截准则,又对现有的准则进行了推广。     

基于可视化交互的国动指挥所设计

国防动员的指挥控制中大量的信息数据(如部队需求、地方资源)和错综复杂的多方关系,使得指挥员难以在短时间内从浩如烟海的信息中提取有用的决策信息和作出快速准确地指挥协调。为此,着眼未来指挥所的发展趋势,提出基于可视化交互的国动指挥所设计方法:通过分析国动指挥任务的关键路径,提取重要的决策信息,利用可视化交互技术,实现对国动任务的信息化指挥控制。以某部演习的国防动员指挥为例,验证了方法的可行性和有效性。     

A trajectory for homeland ballistic missile defense

The Ground-based Midcourse Defense system is intended to protect the US homeland against limited attacks from intermediate- and long-range ballistic missiles. It has succeeded in intercepting target missiles and can engage a threat launched from North Korea or the Middle East, targeting any point in the USA. Nevertheless, high-profile struggles and program changes related to homeland ballistic missile defense (BMD) continue to make headlines. The most significant struggle has been a string of three straight intercept test failures over five years, followed by the recent successful intercept test in June 2014. This article first briefly reviews the current threats of concern. It then examines homeland BMD policy objectives, followed by the current major technical issues in supporting these objectives and, then, the likelihood of negating a warhead. Finally, it highlights major considerations that should be part of the trajectory the US government takes moving forward.     

From rivals to partners: AirSea Battle and the US air force–navy relationship

AirSea Battle (ASB) has generated significant publicity, controversy, and debate among scholars, analysts, commentators, and observers of US defense strategy. However, a research gap exists concerning formal analysis of the impact of the operational concept on the relationship between the US Air Force (USAF) and the US Navy (USN). The impact of the ASB operational concept on the USAF–USN relationship is examined across the issue areas of strategy, budgets, weapons procurement, and training. These four issue areas represent important areas of historical conflict and competition between the Air Force and Navy. The conclusion is that ASB is ushering in a new era of Air Force–Navy partnership that advances the inter-service dynamic from “jointness” toward integration. The emergent USAF–USN partnership therefore represents a significant development in US defense politics and defense strategy.     

Epidemics,national security,and US immigration policy

What are relationships between epidemics, national security, and US immigration policy? This question is important because it sheds light on transnational or nontraditional security areas, American immigration policy, and a pressing issue for US leaders who have recently faced epidemics such as the West Africa Ebola outbreak that began in 2013. This article answers it and lays ground in the area by reviewing epidemics in world history, using International Relations and Security Studies works to specify dangers of contagions for states, and identifying three general immigration measures that American leaders have utilized from the seventeenth century to the present day to protect against contagions, which are (1) policies restricting entrance of foreigners thought to carry specified diseases, (2) the isolation or quarantining of immigrants with contagious disease, and (3) delegating the President with authority to stop immigration in the event of an epidemic abroad. This study has implications for research and contemporary US immigration policy.     

韩国军事改革探析

韩国自20世纪80年代以来积极推进系统性军事改革,特别是卢武铉政府的《国防改革基本计划2006-2020》,充分吸收先前改革经验教训,通过法制化实现了此后历届政府的继承与坚持,引领着韩军当前及未来的建设方向。韩国当前军事改革在主动适应国际新军事变革发展潮流的同时,充分结合自身实际,在作战思想、指挥体系、编制体制、国防管理等各领域均表现出较强的针对性,致力于实现部队的减员增效和均衡发展,推动自主国防建设,提升应对朝鲜军事威胁的能力。同时,韩军在改革过程中,也暴露作战能力受到质疑、军费预算跟进不足,兵源难以为继等系列问题,成为影响韩国军事改革实施进度和最终成效的不确定因素。     

纳米技术与国家安全

纳米技术的兴起为全世界带来了一场全新的科技变革。纳米技术在信息、化工、医药、农业、环保、航空航天等众多领域具有重要的应用价值和广阔的发展前景,被誉为21世纪的三大高新技术之一。然而,经过近五十余年的发展,纳米技术的"双刃剑"效应逐渐显现,纳米技术的滥用对国家安全可能产生的风险正在日益积聚,集中体现在人类健康与生态环境、国家经济安全、国防安全等领域。     

基于三维科研态势演化图谱的国防科技发展评估

当前随着信息技术的深入发展,大数据时代已经悄然而至。大数据为国防科技发展带来了重大机遇的同时,其所带来"数据眩晕"和"数据冗余"效应不容忽视。面对大数据对国防科技发展所带来的巨大挑战,准确、快速、实时地把握和预测科研发展态势,已经成为科研工作者和科研管理高层决策者的迫切需要。在对传统科学知识图谱深入研究的基础上,本文提出一种基于网络和单词分布式嵌入的三维态势演化图谱模型,模型充分利用了文献中的结构信息和语义信息,并对结果进行可视化展示,实验表明,该方法对于掌握国防科技发展动向,挖掘技术前沿,把握技术机会,促进国防科技发展具有较大的参考价值。
