建立新型消防勤务机制探索

随着经济社会的快速发展,消防部队的职能也正在由过去的单一灭火向多元化灭火救援发展,这就给消防勤务工作提出了研究的新课题,揭示了目前消防部队在勤务机制中遇到的警力严重不足、灭火救援骨干队伍薄弱、灭火救援训练效率不高、适应现代灭火救援作战的观念意识不强等突出问题,论证了消防勤务机制改革势在必行,并提出了应采取的四个方面的改革措施。     

重大活动防爆安全检查面临的困难及对策

重大活动防爆安全检查工作涉及的点多、线长、面广,内容十分广泛,参与部门较多,装备器材需求量大,防爆安全检查工作的计划、组织、指挥、协调、保障及具体检查实施将面临一定的困难。做好重大活动防爆安全检查工作．要建立高效顺畅的防爆安全检查指挥机构,制定切实可行的安检方案;要强化科技致胜的意识,进行有力的装备保障;要运用科学的方式方法,加强宣传沟通,争取群众的支持配合;要增强服务意识,缓和警卫形式。

Dynamic capacity reservation and due date quoting in a make‐to‐order system

We consider a make‐to‐order manufacturer facing random demand from two classes of customers. We develop an integrated model for reserving capacity in anticipation of future order arrivals from high priority customers and setting due dates for incoming orders. Our research exhibits two distinct features: (1) we explicitly model the manufacturer's uncertainty about the customers' due date preferences for future orders; and (2) we utilize a service level measure for reserving capacity rather than estimating short and long term implications of due date quoting with a penalty cost function. We identify an interesting effect (“t‐pooling”) that arises when the (partial) knowledge of customer due date preferences is utilized in making capacity reservation and order allocation decisions. We characterize the relationship between the customer due date preferences and the required reservation quantities and show that not considering the t‐pooling effect (as done in traditional capacity and inventory rationing literature) leads to excessive capacity reservations. Numerical analyses are conducted to investigate the behavior and performance of our capacity reservation and due date quoting approach in a dynamic setting with multiple planning horizons and roll‐overs. One interesting and seemingly counterintuitive finding of our analyses is that under certain conditions reserving capacity for high priority customers not only improves high priority fulfillment, but also increases the overall system fill rate. © 2008 Wiley Periodicals, Inc.

空间救援发射窗口分析

从发射窗口的基本特性出发,推导了空间救援任务发射窗口的解析求解方法.将空间救援发射窗口问题分解为平面窗口问题和相位窗口问题,分别建立了平面窗口与相位窗口的解析求解模型,最后获得了发射窗口解析解.用直观曲线描述了同一经度的不同纬度所有发射点对应的发射窗口,为空间救援任务发射窗口的分析和快速计算提供了基础.     

随机共振理论在雷达信号截获中的应用

雷达侦察主要通过无源侦察接收设备对空域中敌方雷达辐射源信号进行检测,若要实现对敌辐射源信号的截获,基本条件就是敌雷达信号能量能够达到雷达信号侦收设备的截获灵敏度。然而现代战场中,电磁环境复杂多变,敌雷达信号往往被干扰信号、噪声等掩盖,导致侦收设备漏警概率提高。针对以上问题,提出基于随机共振原理的雷达信号截获判断的方法,增大了截获信号的输出信噪比,解决了由于噪声过大掩盖的雷达信号的侦收问题。将该方法应用于雷达告警接收机的前端截获部分,大大降低了截获系统的漏警概率,保证了整个截获系统的稳定性。仿真实验验证了该方法的有效性。     

‘Responsibility to protect’ and the African Union: Assessing the AU’s capacity to respond to regional complex humanitarian and political emergencies

Despite its many institutional and political weaknesses and limitations, the African Union (AU) has been developing a variety of tools and mechanisms to respond effectively to complex disasters and emergencies (both natural and manmade) by building up a comprehensive regional security architecture. Furthermore, it has become the first and only regional or international organisation to enshrine the principle of ‘responsibility to protect’ (R2P) in its Constitutive Act. This regional approach to and formal endorsement of the R2P principle allowed it to assume a particular place in the promotion of peace and security in its area. This article aims to critically assess the effectiveness of the AU on the African continent by exploring its real capacity in preventing and responding to emergencies and violent conflicts, and therefore in rendering the principle of R2P operational. The article argues that the formalisation of principles does not necessarily mean their effective implementation. The organisation's use of the R2P principle is also greatly conditioned by internal and external factors.
