由于决策个体控制战场作战平台资源实体,通过平台资源实体执行作战任务,作战平台资源实体在任务上的聚集导致决策个体间需要复杂的交互协作与交流,兵力编成需要为任务的执行创造良好的交互结构。基于任务执行的兵力编成包括两方面的内容:一是指控决策结点间的协作关系;二是指控决策结点间的指挥关系。本文基于决策个体在任务上的协作关系设计兵力编成的指挥关系,以最小化编成中总的协作工作负载为目标,并描述了编成指挥决策关系的生成过程,对生成过程的求解采用了优化协作树算法。 相似文献

在联合火力打击战役中,计划上的潜在缺陷容易造成己方部队的行动冲突甚至误伤,利用兵棋系统中的联合作战计划子系统提供的冲突校验功能,对将要执行的联合火力打击计划中可能存在的缺陷进行校验,可以有效避免冲突的发生。首先对联合作战计划子系统中所有火力打击计划进行数据预处理,采用聚类分析的方法得到火力打击覆盖区,其次计算时间最短条件下己方机动部队的最优路径,最后对火力覆盖区与路径的冲突进行校验,得到冲突地点和冲突时间。在多次兵棋推演中,联合作战计划子系统采用此方法对联合火力打击计划进行冲突校验,实验结果验证了该校验算法的可行性。 相似文献

针对军事任务计划执行环境中普遍存在的资源不确定性,提出了基于资源缓冲区的军事任务计划预测调度算法。算法首先基于平台有效资源功能向量进行任务—平台分配,分配过程中通过调节平台有效资源功能向量,获得不同的平台资源缓冲区分配方案;然后基于NSGA-Ⅱ算法框架对军事任务计划进行多目标求解,进而获得问题的Pareto最优解集。文章通过仿真算例对算法的可行性和有效性进行验证,实验结果表明,该算法能够有效求解资源不确定军事任务计划问题。 相似文献

针对联合作战环境下的装备资源精确保障协同规划问题,考虑以所有保障任务完成时间最短为目标,以保障任务的执行时序和资源需求、保障编组占用冲突,以及资源平台能力更新机制等复杂条件为约束,构建数学模型,提出了基于动态列表调度(Dynamic List Scheduling,DLS)和自适应进化变异二进制蝙蝠算法(Adaptive Mutation Binary Bat Algorithm,AMBBA)的混合装备资源协同保障规划方法.通过动态列表调度选择当前执行保障的任务,在二进制蝙蝠算法寻优中引入自适应学习因子以平衡全局搜索和局部搜索能力,通过在当前可用资源集中搜索最优解为选定任务分配资源,以复杂地域联合作战为例仿真并验证规划效果,结果显示,所提方法可对大规模装备资源协同分配保障问题进行精确高效求解. 相似文献

The US Army has two approaches to counterinsurgency operations in Afghanistan. One is hard, or combat-focused, and the other is soft, or development-focused. This study examines two US Army task forces deployed to Panjwai District, Afghanistan from 2012 to 2013. CTF 4-9 and 1-38 offer a meaningful comparison because they pursued these contrasting approaches among the same population and against the same enemy at the same time and place. The study compares each unit’s approach and finds that neither approach was successful absent the other. The article concludes by recommending further research into combining the approaches at the operational level. 相似文献

Recent events demonstrate the complex and adaptive approach employed by Russia to reassert influence in Europe. The changing face of Russia’s strategy commenced in 2007 when it launched a crippling cyber-attack against Estonia. This was followed by a large Russian conventional attack against Georgia in 2008, occupying two large areas of the nation. 2014 witnessed the Russian annexation of Crimea where in just a week, Russia seized control of Crimea “without firing a shot.” The annexation of Crimea was rapidly followed by a Russian inspired and led subversive war in eastern Ukraine. The common thread among these diverse Russian operations is its use of ambiguity to confound and confuse decision makers in the West. 相似文献

The surprising ‘Arab Spring’ raises the question as to what would enable national intelligence to provide high quality warnings prior to the eruption of popular revolutions. This article uses new sources of evidence to trace and explain Israel's success in comparison to US failure at correctly estimating the course of the Iranian Revolution in 1977–79. In explaining this variance, the article shows that it was mainly the result of the intimate acquaintance of Israel's representatives in Iran with the local language, history and culture, as well as the ability to communicate with locals – tools which the Americans completely lacked. 相似文献

继续教育作为终身教育的重要组成部分和基本形式,对教师的发展成长意义重大。继续教育工作开展十多年来,取得了一定的成绩,但还存在不少问题,如学习动机较为被动,管理认识不到位,教学内容陈旧空泛,教学方法呆板机械等。随着课程改革的不断深入,继续教育必须采取相应的改进措施,树立以人为本,服务至上的观点,教学内容的前瞻性与实用性并重,教学人员进行整合,教学方法灵活多样,评价考核规范科学等,以此激活受训教师内在的学习动机,更大程度地提高继续教育培训的实际效果。 相似文献

In 1796 a 13-year-old boy playing on wasteland behind his father’s house in Ribchester, Lancashire discovered an assemblage of over 30 Roman artefacts, including a decorated brass helmet. Although partially corroded the Ribchester helmet is a fine example of a first-century AD cavalry sports helmet. This article considers how the interpretation of the helmet has evolved since its discovery. The multi-faceted iconography of the helmet with its mural crown diadem is that of an elite soldier and is paralleled in other examples of cavalry sports helmets of the Ribchester type. The long-neglected imagery on the helmet bowl is reinterpreted and seen not as a haphazard collection of randomly placed combatants but as a highly structured, symmetrical composition specifically designed to be viewed from different directions. 相似文献

This article provides an in-depth examination and analysis of the 2006–2009 Tuareg rebellion in Mali and Niger. It identifies the underlying reasons behind the rebellion, explores contrasting counter-insurgency (COIN) strategies employed by the two governments, and presents some lessons learned. While both COIN approaches ultimately produced similar peace settlements, the article argues that the Malian strategy of reconciliation combined with the selective use of force was far more effective than the Nigerien iron fist approach at limiting the size and scope of the insurgency and producing a more sustainable peace. It concludes by looking at the role of external actors, particularly the United States, and how the failure to internationalize the conflict was actually more beneficial to the local COIN effort, as well as to the longer strategic interests of the United States in the region. 相似文献
