Conflict management in the Central African Republic: making genocide prevention work

This commentary analyses the international response to the crisis that struck the Central African Republic (CAR) in early December 2013. It examines three intertwined dimensions defining the courses of action available to policymakers dealing with pre-genocidal crises: the politics and institutional manoeuvring shaping the United Nations (UN) Security Council's decision to authorise an enforcement mission without deploying ‘blue helmets’ on the ground; the operational complexities involved in launching rapid reaction forces; and the interdependent logics between peacebuilding and atrocity prevention. The author argues that there are three ways for the UN Secretariat to ensure a more effective response to CAR-type situations: generating political will to respond swiftly to deteriorating crises leading to widespread abuses of human rights by advancing the concept of Responsibility to Protect as a core component of states' national interests; developing strategic frameworks for the deployment of multi-plural missions equipped to avert the actual or potential threat of atrocities; and developing joint early warning and scenario planning between peacebuilding and atrocity prevention agencies.     

装甲装备器材库存超(欠)储状态分析与程度评价

定义了装甲装备器材库存超(欠)储的概念,提出了维修保障资源点器材储存状态的定性判别和量化方法;考虑数量、时间、空间等影响因素,提出了资源点维修器材超(欠)储程度的评价指标和评价方法,并结合某军区实际数据进行了验证。结果表明:资源点的平均超(欠)储程度反映了保障体系内所有资源点库存偏离正常水平的平均程度,可为确定调剂资源点的优先次序和供应数量提供依据。     

Multidirectional scheduling scheme in resource‐constrained project schedulingproblem

In 2000, Klein showed that bidirectional scheduling schemes (bidss) outperform single‐directional scheduling schemes (e.g., forward or backward schemes). In 2010, Yoosefzadeh, et al. [J Math Model Algor 9 (2010), 357–373] showed that depending on the nature of the problems and also the type of priority rules used, schedules produced by a so‐called tridirectional scheduling scheme (trdss) yields shorter makespans when compared to forward, backward, and even bidss. Since the justification technique is applied in many of the state‐of‐the‐art algorithms nowadays, we show that the tuned version of the trdss outperforms the double justification technique. Moreover, we investigate the circumstances under which the trdss is more probable to generate schedules with shorter makespans. To this end, we introduce a new measure of resource requirements and their distributions, namely total amount of overflows. Our analytical as well as empirical investigations show that when the new measure is increased, it is more probable to obtain schedules with shorter makespans using the trdss. © 2013 Wiley Periodicals, Inc.

有源干扰条件下基于NSGA-Ⅱ的雷达网优化部署方法

在有源干扰条件下,雷达网部署直接影响着防区内指挥信息系统的预警监测能力。由于防区内由分散于不同位置,且重要度不同的责任区组成的,那么实现全方位全纵深的预警能力,将是雷达网部署的重要方面。根据覆盖系数和重叠系数为主要优化目标,基于NSGA-Ⅱ算法进行多目标优化。首先定义了覆盖系数和全局重叠系数两个指标,尤其是全局重叠系数打破了以往重叠系数的概念,从全局出发引导雷达网优化部署;同时,提出基于NSGA-Ⅱ的多目标优化部署算法,采用诱导跳跃、基因到位、诱导交叉等候选解生成方式,保持种群多样性,提高算法收敛性。实验表明,部署优化算法耗时较低,不同干扰源部署态势使网络节点部署产生较大差异,多样的候选解生成方法明显提高了算法的收敛速度。
