改革国防科技评价制度,完善国防科技评价体系

国防科技评价是国家科技评价的组成部分,是国防科技管理的重要内容,是构建军民融合创新体系的内在要求。分析了国防科技评价的基本内涵,阐述了构建国防科技评价体系的总体设想,提出了改革国防科技评价制度的几点思考。研究认为,改革国防科技评价制度,完善国防科技评价体,要加强国防科技评价理论研究,重视国防科技评价机构建设,充分发挥第三方评价的作用,建立多元化的国防科技评价体系,完善国防科技专家选择机制,建立健全国防科技评价指标,加快国防科技评价人才培养,优化国防科技评价环境建设。     

技术成熟度多维评估模型研究

技术成熟度直接关系到武器装备的研制和应用。针对技术成熟度评估存在过度依赖专家智慧、操作周期长、费用高;指标单一、可信度缺乏;数据难以获取、评价方法难度较大等问题,研究了技术发展与技术对应文献关系,提出了基于技术分解结构构建技术成熟度多维评估模型,分析了基于S曲线知识图谱划分技术成熟度等级,并以航母电磁弹射器技术为例进行模型验证。研究表明,技术成熟度多维评估模型具有客观、简便、费用低、易操作等特点,可以与TRL互为补充。     

Portfolio analysis for defense: taking account of networking

To manage their assets at an enterprise level, defense organizations have turned to portfolio theory for the planning, analysis and management of their military forces and materiel. Despite being well established in the commercial sector, the application of portfolio approaches in defense is problematic. The vexatious question for defense of how to define and measure benefits arising is complicated by the increased utility and effectiveness achieved through networking of military forces and the equipment they use. The authors discuss the challenges for defense in using a portfolio approach and propose a conceptual model for dealing with the effects arising from networking with information and communications technologies.

射频前端强电磁脉冲前门耦合研究

针对强电磁脉冲能量经天线进入射频前端的威胁,给出强电磁脉冲环境的评估方法,通过分析天线-射频前端工作原理,提出全频带脉冲耦合能量的理论计算公式.并以中馈天线-短波电台为例,用电磁仿真软件CST实现了天线仿真与前端电路仿真的有机连接,得出前门耦合数据及其影响因素,此仿真方案也为更深入分析耦合效应、验证防护技术提供了良好平台.最后根据仿真为前门防护提出若干意见.     

SLOWING DOWN TO KEEP THE LEAD IN MILITARY TECHNOLOGY

We develop a model of military technology competition among states. States can choose to introduce new military technology, mimic rivals’ level of technology, or withdraw from the contest. States can choose to implement any level of technology within their current feasible technologies. We find that states with significant technological leads should sometimes withhold new technologies, only strategically releasing them to trump rivals’ efforts. We develop the model by refining Admiral Jackie Fisher’s roughly articulated concept of ‘plunging’. We then use this refined argument to reanalyze the case of naval rivalries among European powers between the Crimean War and the First World War. Finally, we conclude by discussing the model’s implications for current US military force structure planning.     

Country Survey XIII: Japan's security posture and defense industry prospects

Defense budgets in Japan have been complicated compromises from numerous inputs ‐ including threat perceptions, domestic industrial/technological base development, support for the bilateral security treaty with the United States and internal bureaucratic politics ‐ but with the fall of the former Soviet Union, the clearest justification for higher spending disappeared. Double‐digit defense spending increases that were common in the 1980s have been replaced by annual increases lower than present inflation rates, resulting in negative real growth in the country's defense budget. Domestic economic problems and consistent government pressures for smaller budgets have further slowed annual growth in total spending and have contributed to lower procurement budgets. As a result, the domestic Japanese defense industry is facing far more constrained conditions from the growth years of a decade before.

Government policymakers are examining Japan's regional security environment as well as its alliance with the United States to determine the appropriate course for the country to take in the coming years. The formal security treaty with the United States is likely to remain a major element of government positions, but other aspects of the country's overall security posture are open to debate. Perceptions of a reduced threat environment are fueling additional pressures for defense budget cuts.

The domestic defense industry seeks means to assure its survival in domestic defense markets in this constrained environment. Expansion into overseas markets to offset declining domestic markets is an option that currently is constrained by policy restrictions on arms exports. Industry is advocating re‐examination of those policies and unlike earlier years, government appears willing to respond positively but cautiously to this lobbying.
