信息支援条件下协同空战态势评估研究

针对现有空战态势评估方法表现形式不够直观、模型简单的问题,提出一种将威力场与遗传神经网络相结合的态势评估方法,并将其应用于信息支援条件下的协同空战态势评估.分别从攻击能力、探测能力、电子干扰能力、生存能力、通信能力、告警能力、协同能力以及决策能力等方面构建威力势模型.利用遗传算法优化BP神经网络,并将其应用于编队作战能力评估.最后利用具体算例进行仿真验证,结果表明该方法是正确可行的.相比于传统态势评估方法,该方法在信息支援条件下的超视距协同空战态势评估中具有全面性、直观性、准确性等优势.

Effects of cueing in cooperative search

We consider the effects of cueing in a cooperative search mission that involves several autonomous agents. Two scenarios are discussed: one in which the search is conducted by a number of identical search‐and‐engage vehicles and one where these vehicles are assisted by a search‐only (reconnaissance) asset. The cooperation between the autonomous agents is facilitated via cueing, i.e., the information transmitted to the agents by a searcher that has just detected a target. The effect of cueing on the target detection probability is derived from first principles using a Markov chain analysis. In particular, it is demonstrated that the benefit of cueing on the system's effectiveness is bounded. © 2006 Wiley Periodicals, Inc. Naval Research Logistics, 2006     

违宪审查制度研究

由于我国目前违宪审查、宪法诉讼机制还不完善,所以在司法实践中出现了“宪法私法化”现象。考察了国外有关国家的相关制度,以期对我国建立科学、完善的违宪审查、宪法诉讼制度有所裨益。     

Technical note: Characterization of binomial semivalues through delegation games

Semivalues are allocation rules for cooperative games that assign to each player in a given game a weighted sum of his marginal contributions to all coalitions he belongs to, where the weighting coefficients depend only on the coalition size. Binomial semivalues are a special class of semivalues whose weighting coefficients are obtained by means of a unique parameter. In particular, the Banzhaf value is a binomial semivalue. In this article, we provide an axiomatic characterization for each binomial semivalue. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007     

Spies,advisors, and grunts: Film portrayals of counterinsurgency in Vietnam

Vietnam was a complex conflict, which historians and political scientists have struggled to understand. Some of the bitterest disputes in the historiography revolve around the US approach to counterinsurgency in Vietnam. Many different facets of the war have received the attention of filmmakers, and an examination of their work suggests new ways of thinking about the conflict. This article considers film portrayals of three phases of the Vietnam War – firstly, the early period of ‘political action’, then the advisory period, and finally the Americanization of the war after 1965. It suggests that by examining the experiences of participants in each of these phases, Vietnam War cinema helps to illustrate the problems that faced various American approaches to counterinsurgency in the conflict. Combined with the importance of films in determining popular perceptions of both historical conflicts and counterinsurgency in general, it suggests that they are worthy subjects of study and critique.     

基于“招标—投标”策略的舰艇编队协同反导优化

针对舰艇编队协同防空反导的作战过程,以缩短舰艇编队协同反导的整体拦截时间、降低反导资源的消耗为目标,构建了一种"招标—投标"策略的舰艇编队协同反导优化模型。该模型利用模糊数学和动态规划相结合的优化技术,在单个作战单元需要编队内其他作战单元协同反导的情况下,运用"招标—投标"策略建立满足反导策略的决策方案,能实时、动态的调整舰艇编队整体协同反导策略。
