Defence industrial policy – a sound security strategy or an economic fallacy?

This article explores whether it makes sense for national governments to employ defence industrial policies – such as offsets and discriminatory procurement practices – to support their domestic defence industries. This question has so far primarily been discussed by economists, who have argued strongly against the use of defence industrial policies. This article maintains that these economists fail to address the often complex motivation behind the introduction of these policies. It illustrates these shortcomings by contrasting their arguments against a case study of Norway, which accounts for the country’s use of defence industrial polices from the early post-Second World War era up until today. The article concludes that, depending on their objectives, defence industrial policies can be seen as either a sound security strategy or an economic fallacy.     

Terminal allocation problem in a transshipment hub considering bunker consumption

This article investigates the method of allocating arriving vessels to the terminals in transshipment hubs. The terminal allocation decision faced by a shipping alliance has the influence on the scheduled arrival time of vessels and further affects the bunker consumption cost for the vessels. A model is formulated to minimize the bunker consumption cost as well as the transportation cost of inter‐terminal transshipment flows/movements. The capacity limitation of the port resources such as quay cranes (QCs) and berths is taken into account. Besides the terminal allocation, the QC assignment decision is also incorporated in the proposed model. A local branching based method and a particle swarm optimization based method are developed to solve the model in large‐scale problem instances. Numerical experiments are also conducted to validate the effectiveness of the proposed model, which can save around 14% of the cost when compared with the “First Come First Served” decision rule. Moreover, the proposed solution methods not only solve the proposed model within a reasonable computation time, but also obtain near‐optimal results with about 0.1～0.7% relative gap. © 2016 Wiley Periodicals, Inc.

制约警卫形式改革的体制机制和法制因素分析

警卫工作体制、勤务运行机制和警卫法制是顺利完成警卫任务的制度保障,当其不适应警卫工作的发展要求时,就会成为警卫工作健康发展的掣肘因素,对警卫形式改革也会产生某些负面影响。当前,警卫规格由职务确定的体制,警卫勤务层层加码的运行机制,不合理的警卫勤务质量考评机制,难以实行的警卫危险评估机制,不科学的警卫工作领导管理体制及不健全的警卫法制,已成为制约警卫形式改革的重要因素。     

朝核问题对中国边境安全的影响

朝核问题一直是困扰东北亚地区安全的核心问题,自20世纪90年代第一次朝核危机至今．朝核问题不但没有得到妥善解决,反而更加复杂。2006年10月9日,朝鲜宣布成功进行了地下核试验,朝鲜半岛再一次成为全球关注的焦点。在前人研究的基础上,就朝核问题产生的背景,朝核问题对中国边境地区经济、地区稳定以及生态环境等方面产生的影响进行分析和探讨。     

试论“大警卫”格局的构建

随着我国社会主义现代化进程的不断发展及党和国家领导人对警卫形式的要求,警卫工作的格局也在随社会的进步、发展而不断发展完善。“大警卫”格局的构建需要党委和政府,军、警等武装力量,人民群众等各方面的共同努力。     

关于加强公安现役部队科研环境建设的思考

目前公安现役部队科研环境建设,还存在项目申请难度大、投资渠道单一化、团结协作攻关难、科技资源共享少、学术科研氛围淡等问题,对人才队伍建设造成一定影响。坚持“以人为本”,加强制度建设,解放思想,增加投入,活跃学术氛围,树立科研标兵,以进一步改善和优化公安现役部队科研环境。     

公安现役部队后勤专业人才队伍建设的思考

公安现役部队后勤专业人才队伍建设是后勤信息化建设的重要智力基础,关系到部队后勤全面建设和长远规划。当前,复杂的国际国内形势与繁重的边、消、警任务,对后勤专业技术人才队伍建设提出了更高要求。如何认清形势,更新观念,实现部队后勤工作的跨越式发展,关键在于更快更好地培养融指挥、管理、技术为一体的“复合型”高素质人才。     

一种基于图论的网络安全分析方法研究

随着信息技术安全问题的日益突出,对网络系统进行安全分析日益重要.提出了一种基于图论的网络安全分析方法NEG-NSAM,在进行网络参数抽象和脆弱性关联分析的基础上,构造网络渗透图模型,刻画了威胁主体逐步渗透安全目标的动态过程.针对大规模网络环境,提出了渗透图简化算法.最后,运用NEG-NSAM方法进行了实例分析,验证该方法的可行性和有效性.     

基于内容分析的协议识别研究

为解决多模式同时匹配的协议识别性能问题,提出了一种多模式组合有限状态机;以Thompson算法为基础,提出了一种压缩ε的NFA构造算法,该算法通过减少ε边及其对应状态,有效提高在协议模式编译时,NFA转换成DFA及DFA最小化过程的性能;基于上述理论与算法实现了一种One-Pass的组合多模式协议识别系统.实验表明:结合上述技术实现的系统,编译性能比标准DFA构造过程提高了7倍以上,匹配性能比L7-Filter提高了近20倍.
