国内装备采购研究现状与趋势研究——基于CiteSpace知识图谱软件的可视化分析

本文利用CiteSpace知识图谱分析和可视化工具,从时间分布、期刊来源和作者机构等方面对CNKI中文期刊全文数据库2001年1月1日至2020年6月30日间收录的以"装备采购"为关键词的642篇学术论文及文献进行数据可视化分析,并通过关键词词频共现分析对该领域的高频关键词进行了词频统计。在利用CiteSpace软件对"装备采购"相关文献进行统计分析后,详细论述了装备采购研究的发展趋势,并总结出目前军队装备采购研究的现状与不足,如军队内部科研力量作为装备采购领域研究的核心组成部分,相互间缺乏交流研究;装备采购领域研究方向多元,但基础理论、概念研究不够深入等。在此基础上梳理出优化后期装备采购领域研究发展的建议,以期为完善军队装备采购领域的研究工作提供一定参考。     

大力开展基于智能技术的数字化战例库建设

战例研究是进行军事问题研究的重要基础,也是汲取战争经验、深化军事斗争准备的现实需要。开展战例研究的前提是建立起知识体系完备、检索运用便捷的战例库。随着智能技术的发展,战例数据的标准化描述、规范化存储、智能化分析成为可能,极大地支撑了便捷、高效的数字化战例库系统开发工作。本文首先从战例研究的重要性入手,分析了当前战例运用和研究的基本现状,梳理了存在的典型问题;其次,从数字化技术对战例描述和战例库建设的影响角度剖析了数字化战例库构建的基本需求;最后,通过对智能技术的把握,分析了智能技术对数字化战例库构建的支撑作用,并对如何开展基于智能技术的数字化战例库建设提出了初步设想。     

基于可信度的网络安全性分析方法

提出了一个基于可信度方法的网络安全性分析模型。该模型在脆弱点信息、脆弱点之间的关系、脆弱点与安全性的关系的表示中引入可信度因子,通过不确定推理对主机和网络的安全性进行分析。该模型能综合考虑诸多因素,有效处理安全性分析中的不确定知识。     

部队建设政绩观存在的偏差与调适

树立以人为本,全面、协调和可持续发展的政绩观,是新世纪新阶段部队贯彻落实科学发展观的根本保证。当前部队建设政绩观存在若干偏差,必须通过观念变革、立足基层、提高本领和制度建设来加以纠正和调适。     

对知识经济时代下培养大学生自主创新能力的思考

随着知识经济时代的到来,自主创新能力是经济和社会发展的重要支撑。作为高等学校,担负着培养自主创新能力人才的任务,但是传统的高等教育观念,制约着学生自主创新能力的形成和发展。如何更新高等教育观念,积极探索培养学生自主创新能力的新途径,是每个教育工作者需要认真研究和思考的新课题。     

舰艇协同作战导弹防御模型研究

舰艇协同作战是未来战争的主要作战形式,导弹防御是其主要的作战职责.运用信息论的方法对舰艇协同作战中敌方导弹发射策略的不确定性进行建模,运用可靠性理论对协作效果进行建模,并引进知识的概念作为其度量,同时用边的函数对网络复杂性进行建模,综合这两种因素在以最大化防御时间为总的决策目标,以己方导弹储备和敌方来袭速率为决策因素对导弹防御作出辅助决策.     

Optimization and mediated bartering models for ground delay programs

The Federal Aviation Administration (FAA) and the airline community within the United States have adopted a new paradigm for air traffic flow management, called Collaborative Decision Making (CDM). A principal goal of CDM is shared decision‐making responsibility between the FAA and airlines, so as to increase airline control over decisions that involve economic tradeoffs. So far, CDM has primarily led to enhancements in the implementation of Ground Delay Programs, by changing procedures for allocating slots to airlines and exchanging slots between airlines. In this paper, we discuss how these procedures may be formalized through appropriately defined optimization models. In addition, we describe how inter‐airline slot exchanges may be viewed as a bartering process, in which each “round” of bartering requires the solution of an optimization problem. We compare the resulting optimization problem with the current procedure for exchanging slots and discuss possibilities for increased decision‐making capabilities by the airlines. © 2005 Wiley Periodicals, Inc.

Patents and Dual-use Technology: An Empirical Study of the World's Largest Defence Companies

Abstract

This paper examines the generation of technological knowledge by leading companies in the defence industry. In particular, we test whether the characteristics of large defence companies are related to both the production of different types of patents (civilian, military and mixed), and the generation of dual-use technologies. To explore these links, we rely on economic data for the top 100 defence companies from the Stockholm International Peace Research Institute database, and patent information from the Worldwide Patent Statistical Database. Our results show that the relationship between the production of civilian patents and the size of the company is positive and significant. However, this relationship does not hold for the production of military patents. Furthermore, the military commercial profile is unrelated to the generation of military patents. Regarding the involvement in dual-use technologies, firms engaged in dual-use are those with higher military sales, a greater number of employees and a larger number of patents (civilian, military and mixed) than those not engaged in dual-use. Furthermore, we found a skill effect (more involvement in dual-use per employee) in European firms compared to US firms. These findings help to identify which firms should be targeted by government policies if increasing dual-use technologies becomes a political objective.     

利用网络动力学评估复杂社会网络知识传播性能

为了对复杂社会网络知识传播性能进行评估,提出了利用复杂网络动力学和知识传播指数相结合的评估模型,该模型综合考虑了网络的拓扑特性、个人的知识普及能力和对知识的感兴趣程度,通过网络知识传播指数阈值的大小来衡量网络的知识传播性能.通过仿真发现,知识在社会网络中的传播对均匀网络平均度值和无标度网络初始传播节点度值的依赖性小,对知识传播指数的依赖性大;在相同条件限制下,无标度社会网络的知识传播性能要高于平均度值相等的均匀社会网络.
