基于“综合赋权”模糊物元模型的机场运行安全评价

为了保证机场运行安全,防止事故的发生,依据模糊物元分析理论,结合机场运行安全评价指标体系,构建了基于综合赋权的机场系统模糊物元安全评价模型。在该模型中,通过层次分析法和熵值法主客观综合所确定的权重,为指标体系进行线性加权,实现综合赋权,从而将计算得到的综合权重用于模糊物元建模与评价。实例分析结果表明,该模型步骤简单,过程科学合理,并兼顾了主客观因素的影响,评价结果总体反映了机场的真实安全水平,也为机场安全的科学评价提供了新思路。     

Peace enforcement in Africa: Doctrinal distinctions between the African Union and United Nations

When the United Nations (UN) Security Council needs to authorize a peace enforcement operation in Africa, its partner of choice is the African Union (AU). Africa has developed significant peace operations capacity over the past decade. In addition to deploying eight AU operations, Africa now contributes 50% of all UN peacekeepers. African stability operations, like its mission in Somalia, are often described as peace enforcement operations. In this article, I question whether it is accurate to categorize African stability operations as peace enforcement? I answer the question by considering what the criteria are that are used to differentiate between peace enforcement and peacekeeping operations in the UN context. I then use the peace enforcement criteria to assess whether AU stabilization operations would qualify as peace enforcement operations. In conclusion, I consider the implications of the findings for the strategic partnership between the AU and the UN.     

基于LOB的辐射源无源定位算法对比研究

分析了4种具有代表性的基于辐射源方位线(Lines Of Bearing,LOB)的无源定位算法,即Pages-Zamora定位算法、布朗定位算法、概率定位算法和模糊定位算法。在此基础上提出了融合-迭代定位算法,并进行了蒙特卡罗仿真对比实验,对5种算法的定位精度和运算量进行了比较分析。实验结果表明:融合-迭代定位算法的综合性能优于其他定位算法。     

浅谈“合训”学员“能打胜仗”的素质能力培养

习主席提出的强军目标,能打胜仗是核心,关键在人才。武警院校作为武警初级指挥“合训”人才培养基地,要紧紧围绕“能打胜仗”要求,加强政治、军事素质和战斗精神培养,使培养的学员懂打仗、会打仗、练打仗、打胜仗,真正成为“一懂五会”的合格人才。     

潜艇自航模控制系统设计

为满足自航模操纵性试验的需要,设计了潜艇自航模控制系统的结构,建立了基于TCP/IP的网络通信协议,为保障自航模操纵性实验的安全性,设计了应急处理流程,通过对自航模定深控制过程的分析,完成了升降舵模糊控制器的设计。基于实现的自航模控制系统在操纵性实验中表现良好,对于类似系统的设计与实现具有一定借鉴意义。

针对INS/GPS制导炸弹对地面目标的精确打击问题,提出带落角约束的模糊变结构制导律。在变结构制导律的基础上,引入终端落角约束项,应用模糊规则对所设计制导律中的变结构开关项系数增益进行在线调节。仿真结果表明,在对地面目标进行攻击时,该制导律降低变结构控制系统的抖振,同时满足制导精度和期望落角的要求,具有有效性和鲁棒性。     

基于粒子群优化的模糊交通控制器设计

城市中存在着一些关键路口,其交通通畅与否会对周围路网的交通流起着很大的影响,这些路口需要优先保持通畅.针对此情况,设计了基于上下游交通信息的二级模糊交通控制器来对路网进行协调控制.在此基础上,提出了针对交通特性改进的粒子群优化算法（TIPSO）,并采用TIPSO对第一级模糊规则进行优化,实验结果表明TIPSO对模糊规则具有较好的优化效果,能够离线训练,获取到比人工设定的更优的模糊规则.

A gentle occupation: unravelling the Dutch approach in Iraq, 2003–2005

This article examines the so-called ‘Dutch approach’ to conducting stabilisation operations. The term is mostly used in relation to the mission carried out by the Netherlands armed forces in Afghanistan's Uruzgan province from 2006 to 2010, but actually originates in the Iraqi province of Al Muthanna. Here, a 1350-strong battle group operated from July 2003 until March 2005 as part of the US-led coalition, after which the Dutch forces left Iraq relatively unscathed and self-confident of their ability in dealing with this type of conflict. On the basis of archival research and interviews, the authors unravel the ‘Dutch approach’ in southern Iraq by tracing its roots and by examining the Dutch operation in the context of the American and British experiences. They argue that despite predominantly effective tactical reflexes and an overall adequately broad interpretation by battle group commanders of a too narrowly defined political mandate, stability in Al Muthanna was conditions-driven rather than the result of a unique and effective approach. The term ‘Dutch approach’ turned out to be a convenient fabrication which, after the relatively successful mission in Al Muthanna, became increasingly politicised in the run-up to a dangerous new operation in southern Afghanistan.
