军用飞机综合效能/费用评估方法

军用飞机的效能与费用是两个相互制约的因素,对两者进行科学合理的综合评估,对于军用飞机的发展和使用有着很重要的意义。在分析综合效能/费用的基本评估指标基础上,提出了在军用飞机全寿命周期综合效能/费用评估指标,重点对作战使用阶段的最佳效能/费用进行评估分析,最后给出结论。     

不平衡数据的软件缺陷预测方法

数据的不平衡问题是数据分类领域中的一个热点问题。当分类算法处理这些数据时,算法将偏向多数类而忽视少数类。在软件缺陷预测领域,它并没有引起足够的重视,在4组NASA不平衡数据上比较和分析了14种分类算法的性能,为了克服数据的不平衡性,采用SMOTE技术对软件缺陷数据进行平衡化,最后在AUC和F-measure评价指标下对算法进行评估。实验结果表明随机森林算法在4组数据上表现最佳,这为软件缺陷预测提供了很好的参考。

Regional Support for Afghan Insurgents: Challenges for Counterinsurgency Theory and Doctrine

After the fall of the Taliban regime in 2001, several thousand Afghan Taliban forces fled across the border to Pakistan, and the area became a safe haven for Afghan insurgents. In 2014, the transnational dimension of the insurgency is still highly prominent. Although regional support for insurgents is not uncommon, how to counter this aspect is mostly ignored in counterinsurgency (COIN) theory and doctrines. In this article, a regional counterinsurgency framework is developed, using the regional counterinsurgency efforts in Afghanistan as an example. The framework will facilitate the systematic inclusion of regional COIN measures in theory and doctrine.     

Generalized orienteering problem with resource dependent rewards

We introduce a generalized orienteering problem (OP) where, as usual, a vehicle is routed from a prescribed start node, through a directed network, to a prescribed destination node, collecting rewards at each node visited, to maximize the total reward along the path. In our generalization, transit on arcs in the network and reward collection at nodes both consume a variable amount of the same limited resource. We exploit this resource trade‐off through a specialized branch‐and‐bound algorithm that relies on partial path relaxation problems that often yield tight bounds and lead to substantial pruning in the enumeration tree. We present the smuggler search problem (SSP) as an important real‐world application of our generalized OP. Numerical results show that our algorithm applied to the SSP outperforms standard mixed‐integer nonlinear programming solvers for moderate to large problem instances. We demonstrate model enhancements that allow practitioners to represent realistic search planning scenarios by accounting for multiple heterogeneous searchers and complex smuggler motion. © 2013 Wiley Periodicals, Inc.

Rubber match: a third Lebanon war

Israel and Hezbollah have applied the lessons learned from the 2006 Lebanon War and have been preparing for a future conflict with both sides aiming for a more decisive victory. With improved capabilities from 2006, future hostilities will be far more destructive. This article analyzes their performance in 2006 and the lessons they have drawn to predict what a future conflict is likely to look like. The article analyzes both parties in three categories: ground forces; rockets, missiles, and anti-armor weapons; and lastly, Israel's air and sea dominance and Hezbollah's efforts to counter that dominance. Finally, this article argues that, contrary to conventional wisdom, a large-scale conflict between Israel and Hezbollah is unlikely to become a larger regional conflict involving Syria and Iran.
