灰色关联投影法的威胁排序算法

威胁评估与排序是作战系统和C4I系统必须具备的重要功能.结合多指标决策理论和灰色系统理论,提出了基于多指标决策灰色关联投影法的威胁排序算法.首先通过建立灰色关联判断矩阵将威胁排序转化为多指标决策问题;其次为缩小极端值的影响提出了基于信息熵的威胁指标权重算法;最后从矢量投影角度应用灰色关联投影值进行威胁排序;并分别研究了分辨系数和指标权重对威胁排序的影响.通过现代防空作战实例验证了算法的有效性和工程实用性.     

模糊群体决策的多方案评价方法

针对多方案评估中因素评价难于精确表示的问题,提出了一种基于模糊语言变量和OWA(OrderedWeightedAveraging)集结算子的群体评价模型与方法,给出各因素的方案两两对比偏好语言评价值,并通过对多决策者、子因素、主因素的三次集结和对模型中α值的恰当选取,可得到方案集的优序排列。该方法可行、有效,可为群体决策提供新的途径。     

基于模糊折衷理论的目标威胁度综合评价模型

由于海洋环境的复杂性和水声信道的特殊性,多目标跟踪过程中的目标威胁评估一直是水声信号处理领域的突出难题.目标威胁度是目标分配的重要依据,必须综合考虑目标的多种特征信息.针对水下声自导系统,提出了目标威胁度评估指标体系,构建隶属度函数对各个指标进行了量化,并建立了基于模糊折衷的目标威胁度综合评价模型.仿真结果证明该方法能有效节省航程,为提高水下航行器的作战效能提供了有效途径.     

基于可变权重模糊集的搜索方案模糊决策模型

运用模糊决策理论,研究了反潜巡逻机在执行反潜任务时,从多种搜潜手段及其组合中选择合理的搜潜方案的决策模型,特别是针对声纳浮标为消耗性器材的特点,引入了基于AHP方法思想的、与声纳浮标存有量有关的可变因素权重模糊集向量,通过计算和判断各种备选方案与理想方案之间的模糊距离,建立了针对不同航行状态潜艇的搜索行动方案优选模型,最后给出了决策算例,验证了模糊决策模型的合理性,可应用于反潜巡逻机作战指挥的计算机辅助决策.     

Lesotho’s 2015 elections in the context of an ongoing security vacuum

After inconclusive elections in 2012, Lesotho had a coalition government for the first time, made up of three political parties that had a narrow majority in parliament. The new government, however, faced several challenges, some of which were of its own making. The agreement among the three parties was to literally divide the government into three parts, leading to a continuous stalemate in its operation; the most serious consequence was the prorogation of parliament and the resultant attempted coup. The flight of the prime minister to South Africa and his return under a Southern African Development Community (SADC) security detail provided a short-term solution to Lesotho's security crisis. Under Cyril Ramaphosa's mediation, the prorogued parliament was conditionally opened and the election date set for 28 February 2015. However, the security dilemma – whereby the prime minister, who is also minister of defence, has no control over the military – remains. When elections are held, there does not seem to be a guarantee that they will be held in peace; moreover, there are now fears that the losers will not accept the results of the elections because of the security vacuum in Lesotho. This article argues that peace can only be salvaged by enhanced SADC security before, during and after the elections. It argues that the SADC mission should remain beyond the elections to oversee the constitutional changes that are necessary for ensuring long-term stability. On their own, Lesotho politicians are unlikely to be able to work together in order to move the country forward.     

EHW实现过程中VHDL程序自动生成研究

论述了在基于FPGA的EHW内进化实验中特定格式的染色体编码表示和相应的VHDL程序自动生成的基本概念,制定了具体规则和方法,奠定了硬件进化及评估过程实现全自动运行的基础,并对自动生成的结果予以实际验证。该方法能在使用不同的FPGA芯片作为演化载体时,避免对不同的数据流进行格式分析,以便在通用的EDA环境中,直接实现以二进制数串表示的染色体自动处理和相关配置文件的形成。按此方式可在很大程度上摆脱对某些固定类型FPGA芯片的依赖,有助于建立方便、实用的EHW环境。     

救捞工程中的多指标决策方法探讨

建立了基于综合权重的双基点多指标决策模型。分别从主观和客观两个方面来分析评估指标的权重,迭加得到综合权重,并利用它进行相对贴近度分析,从而判断方案的优劣,得到最佳方案,使问题的优化与决策更加科学、合理。以拖带方案的优化决策分析为例,验证了多指标决策模型的可行性,简述了它在救捞工程中的应用方法。

首都周边维稳预警机制研究

在构建首都大周边维稳预警机制中,情报工作具有监测、预测和辅助决策功能。社情监测离不开情报的收集,维稳社情预测依赖于情报的分析、研判、传递与通报,危害社会安全稳定案件预控离不开情报支撑。做好首都周边地区维稳预警工作,需要健全和完善情报收集制度、情报分析和研判制度、情报送报制度、相关情报工作制度以及社会舆情信息汇集与分析制度。     

When the Going Gets Tough… Monitoring Missions and a Changing Conflict Environment in Sri Lanka, 2002–2008

This article analyzes how the conflict environment in which a civilian monitoring mission is deployed influences the monitors' assessment of the operation. It draws on unique empirical material from the experience of the Sri Lanka Monitoring Mission (SLMM), deployed to oversee a ceasefire agreement in Sri Lanka 2002–2008. With material from a survey and in-depth interviews, experiences of the monitors are analyzed and changes over time are traced in relation to the monitors' assessment of the mandate and organizational set-up of the mission. The study points to the difficulty of monitoring missions to address escalation during an ongoing peace process. Its function is dependent on the goodwill of the parties. In essence, monitoring missions have the potential to strengthen peace when there is momentum in favor of progress, but when relations between the parties turn sour and the conflict escalates a civilian monitoring mission basically loses its potential. During the final stages of the war, which saw a very large number of civilian casualties, the war-torn areas were closed to international observers. Moreover, international pressure for a short-term ceasefire to alleviate the humanitarian situation was dismissed by the Sri Lankan government, which also saw the backing of several important actors, not the least China.
