基于Multi-Agent的防空导弹武器系统模型设计

建立科学的结构模型是进行防空导弹武器系统仿真的基础和关键环节。针对防空导弹武器系统的特点,提出了基于Multi-Agent的防空导弹武器系统模型建模方法,设计了防空导弹武器系统模型结构。利用Multi-Agent建模技术,把防空导弹武器系统实体映射成相应的Multi-Agent系统,并以Agent的形式对防空导弹武器系统这一客观复杂系统进行了深刻的认识,为防空导弹武器系统建模仿真奠定了基础。     

A rent‐seeking model of international competition and alliances∗

This paper presents an alternative approach for analyzing international competition and alliances as rent‐seeking contests that are able to capture the impure public good nature of defense spending. Two‐country Cournot and Stackelberg games are considered and comparative static results derived. A three‐country model is investigated, and alliance behavior is explored in the context of this rent‐seeking model. The conjecture that an alliance may become less effective if the allies’ interests become more closely aligned is verified. Finally, the model is generalized, and a Nash‐Cournot equilibrium is computed.     

ON THE CHOICE OF MULTI-TASK R&D DEFENSE PROJECTS: A CASE STUDY OF The ISRAELI MISSILE DEFENSE SYSTEM

Investments in R&D constitute a major share of the expenditures of the hi-tech industry since, generally, they enable firms to successfully compete in the rapidly and constantly changing markets for hi-tech products and services. The role of R&D projects is particularly important in the areas of defense and homeland security due to the nature of warfare and the continuous threats posed by arms races and by terror organizations. This study analyzes the choice of the R&D projects designed to counter multiple related military threats. It develops the methodology required to assess whether it is preferable to develop one project to thwart several related threats, or several distinct projects, each of which provides an answer to one specific threat or a partial set of the threats. An analytic solution is provided and assessed for two simple models with two related threats. A solution of the model is then provided for any number of related threats, using a dynamic programming methodology. Finally, we demonstrate the usefulness of our model and methodology to Israel’s missile defense problem; that is, we show how to optimally develop systems aimed at thwarting the multiple threats of short-, medium-, and long-range missiles.

Missile defense and strategic stability: Terminal High Altitude Area Defense (THAAD) in South Korea

South Korea is threatened by its troubled relationship with North Korea. North Korea possesses a large cache of missiles as well as chemical and biological weapons, and the future potential to mount nuclear weapons on its missiles. The United States is also challenged because of its defense commitments to Seoul. As a countermeasure, the United States and South Korea decided to deploy Terminal High Altitude Area Defense (THAAD) missile defenses in South Korea. However, China has objected. Chinese scholars believe the THAAD radar would be able to track Chinese inter-continental ballistic missiles, thereby weakening their deterrent. A technical analysis does not support this assertion. However, it is vital for South Korea, given its proximity and economic interdependence, to reassure China. South Korea should highlight that THAAD will be deployed by the United States Forces Korea and is not a commitment by Seoul to become part of U.S.-led missile defenses in the Asia-Pacific.     

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。
