指挥员作战决策行为的EWA学习模型分析

摘要：为在根本上提高作战决策质量,从行为学角度入手,以指挥员这一“人”为中心,并结合认知科学、心理学等知识对指挥员作战决策行为进行研究。从博弈角度出发,通过引入EWA模型,对指挥员作战决策行为进行分析和优化。结果表明,EWA模型,特别是加入“老练”指挥员后的模型能够明显改善指挥员决策行为,对指挥员,尤其是经验匮乏的指挥员决策行为表现有着重要的作用。     

舰用中冷回热燃气轮机装置动态性能分析

中冷回热循环(ICR)燃气轮机因其优越的全工况性能正日益受到船舶和工业领域的关注。通过分析ICR燃气轮机的变工况特性,采用模块化建模法仿真,对ICR燃气轮机进行动态性能分析,并与简单循环燃气轮机仿真结果进行比较。结果表明,换热器的热惯性对机组的动态性能影响较大,时间常数愈大,达到新平衡所需时间愈长;ICR燃气轮机不仅在设计工况点的效率和功率都有明显提高,而且在低工况下仍有良好的经济性,动力涡轮采用进口导叶面积可调可进一步改善ICR燃气轮机装置的部分工况性能。     

一种基于辩论的协作型CGF分层协商模型

针对作战仿真对人类行为表示(HBR)的准确性要求,建立真实反映战场行为的冲突消解模型是非常重要的.根据已有研究的不足和冲突行为分析,提出了基于辩论的协作型计算机生成兵力(CGF)分层协商模型,在给出相关定义的基础上,研究了冲突下的协商行为过程,实现了基于效用理论的论据强度定量评估算法,算法用于实现首选议题的选取和共同信...     

Why they fight? Reconsidering the role of motivation in combat environments

The current combat motivation model based on primary group thesis assumes that the main force behind motivation is peer-bonding or otherwise known as unit cohesion. Cohesion is perceived as an all-encompassing factor that leads to satisfactory (or unsatisfactory in lack thereof) military effectiveness and performance in conflict environments. However, the article identifies three main problems with this perspective: 1. mono-dimensional view of motivation; 2. motivation based on heteronomy, and 3. self-reporting bias. The current model does not consider motivation as a separate entity from cohesion; it does not place motivation as fundamental human value; lastly, it takes motivation as granted by-product of socialization. The article proposes a new combat motivation model based on The Self-Determination Theory. The theory maintains that human motivation requires satisfaction of three psychological needs of competence, relatedness, and autonomy. The degree of satisfaction of those three needs leads to different types of regulated motivations – a continuum from intrinsic to extrinsic – each of which has specifiable consequences for learning, performance, and well-being of an individual.     

灭雷具CGF仿人操控行为建模

灭雷具在动力上受海流和电缆的非线性耦合作用力影响,其水下操控十分复杂。针对灭雷具CGF(Computer Generation Force)系统行为建模的需求,建立了简化的四自由度动力学模型,同时考虑了海流和电缆扰动的影响并对缆长和动力分配进行优化计算以实现最优缆长控制和最短路径规划;综合分析了灭雷具水下操控规则,从动力控制和路径规划两个层次来建立其行为规则库,得到了与实际相符的灭雷具智能体仿人操控轨迹。仿真结果表明了该行为模型的正确性和有效性,能较好的满足仿真系统的需求。     

基于Agent构建群体行为模型

基于Agent建模理论的提出打破了传统方法的局限,为复杂的群体行为建模提供了一条新的途径。将仿真群体中的个体看作独立自主、智能适应的Agent,从微观行为和局部规则入手,重点论述了Agent模型的感知、决策和运动3个方面的设计与实现。实验表明:在没有整体规则的作用下,整个模型能够以涌现的方式生成不同场景中的群体行为仿真,且模型易于构建实现,仿真效果逼真生动。     

Meeting the growing safeguards burden

ABSTRACT

The International Atomic Energy Agency (IAEA) faces challenges in fulfilling its safeguards mandate as a result of an expanding safeguards burden and a relatively static budget. This dilemma has been exacerbated by the additional burdens of implementing the Joint Comprehensive Plan of Action (JCPOA) in Iran, but would not go away if implementation of the JCPOA were to end. There are three main areas of opportunity for the Agency: (1) budgetary expansion tied to changes in staffing policies, (2) changes in safeguards approaches, and (3) technological innovation. Barriers and limitations are associated with each approach, and advancing any of them will face a difficult political environment in Vienna.     

EU Global Strategy in a changing world: Brussels’ approach to the emerging powers

The world is entering a period of power transition, at the outcome of which some new form of global order (or disorder) is likely to emerge. Critical to this process is the interaction between the established powers, the USA and the European Union (EU), and the emerging powers, particularly China, Brazil, India and Russia. Many analysts have classified the EU as a declining power, a perception that has been enhanced with the triple crises of sovereignty that have rocked the Union since the mid-2000s (money, borders and defence). In this context, the publication of the EU Global Strategy was an opportunity for the EU to state clearly the nature of its ongoing and future relations with the rest of the world. This article argues that, in reality, Europe as a bloc (as opposed to its member states severally) has very limited purchase with the other major powers, and an ambivalent or ill-defined grasp of how to engage with them. They, for their part, have difficulty in knowing how to understand the EU as an actor and prefer to deal bilaterally with its key member states.     

拉伸载荷作用下基体表层激光离散预处理对铬镀层／45钢基开裂行为的影响

采用激光离散预处理钢基体再电镀铬层技术得到了一种新型复合结构，研究了这种新型复合结构在拉伸载荷作用下的开裂行为特征，并与无激光处理钢基体的试样在同样试验条件下的开裂特征进行了对比分析。结果表明：有激光离散预处理钢基体试样的承载能力要高于无激光预处理钢基体试样的承载能力，且有激光处理的试样开裂区域在两个激光带之间（无激光处理区），主裂纹呈现明显的周期性特征。本研究结果可归结为激光预处理钢基体不仅改善了基体表层的应力状态和力学性能，而且还改善了后续铬镀层的力学性能。
