面向多星观测调度的分层迭代算法

提出一种基于分治策略的多星观测分层调度框架,在该框架下,用蚁群优化算法把任务分配至各轨道圈次上,并利用自适应模拟退火算法求解各轨道圈次的调度问题。根据各轨道圈次调度结果的反馈情况,再调整任务分配方案,重复上述过程直到达到算法终止条件。为了提高算法的性能,在设计蚁群算法的启发式信息模型时,应充分考虑卫星调度问题的领域知识;在模拟退火算法中设计两个邻域结构,采用动态选择策略在优化过程中确定最佳邻域搜索结构。仿真实验表明,该方法有效地降低了问题求解的复杂度,尤其在求解大规模多星观测调度问题时表现出优异的性能。

Elements of ‘armed non-state actors’ power: The case of al-Qaeda in Yemen

Over the past few years there is an apparent re-regionalization of al-Qaeda activity, intensified by the ongoing Middle East turmoil. Its main characteristic is a trend towards the abandonment of focoist strategies and their replacement by more popular-based ones. This article aims at evaluating their capacity to implement such a strategy shift and sustain the required level of violence. As a means of evaluating this capacity, this article proposes the use of a DIME (diplomatic, informational, military, and economic) framework, which will hopefully provide an alternative angle of theorizing and understanding ‘armed non-state actors’ (ANSAs). The model is applied in the case of al-Qaeda in the Arabian Peninsula (AQAP), which appears to have effectively developed the military and informational dimensions, due partly to its own prowess and partly to the Yemeni state's weaknesses and the shortcomings of counterinsurgency. In contrast, the economic and diplomatic dimensions suffer from the lack of resources and the anti-systemic nature of AQAP.

ANALYSING QUITS AND SEPARATIONS FROM THE ROYAL NAVY

Manning difficulties and retention of skilled personnel is a timely issue in the British armed forces, and especially in the all‐volunteer Royal Navy. Allied with difficulties of matching personnel numbers and posts, significant skill mismatches can take a long time to eradicate, with obvious financial and operational penalties. In the light of these factors, a holistic understanding of the exit behaviour of naval personnel is vital for naval manpower planners. This paper analyses ratings’ voluntary (quits) and involuntary (separation) exit patterns from the Royal Navy using an independent competing risks hazard regression analysis framework. The results show that both voluntary and involuntary exits are pro cyclical with respect to macroeconomic and labour market conditions for both male and female ratings. Male ratings are more likely to quit or separate due to a lack of promotion to higher ranks as compared with females. Male ratings are also more likely to quit as a result of a hectic operational tempo when compared with their female counterparts. Frequency of sea/shore deployments also seems to exert a significant effect with respect to quits and separation outcomes of both genders. In terms of marital status married males are less likely to quit compared with their unmarried male counterparts, whereas the opposite is the case for female ratings.
