基于模糊理论的空袭目标威胁判断模型 总被引:9,自引:1,他引:8
对空袭目标威胁度进行合理排序是提高防空效能的重要因素。分析了影响空袭目标威胁度的各种因素,利用模糊综合评判的思想,建立了一种进行目标威胁判断的模型,并根据具体情况给出了排序的合理方法。通过实例,给出了具体的计算过程,并将此方法得出的结果与文献中的方法得出的结果进行了比较,充分说明了模型的可行性。 相似文献

This article explores the livelihood pathways of serving Ugandan Army soldiers and traces their methods and motivations for enlistment. All were from areas of northern Uganda affected by nearly two decades of violent instability. With the Uganda People's Defence Forces (UPDF) increasing recruitment eligibility requirements and taking other measures to improve professionalism, some soldiers enlisted using false credentials and names, travelled to skirt unofficial ethnic quotas, and joined against their family's wishes. The Army's defence reform process was intended to preclude such problems. The article concludes with reflections on what strategic deception (by both recruits and the Army) may imply for warriors' honour. 相似文献

ABSTRACTThis article uses the case of illegal street vending in Harare to explore the interface between urban governance and politics. Drawing on the ideas of urban governance and informal governance, it illustrates how polarisation between the opposition political party Movement for Democratic Change-dominated municipal council and the Zimbabwe African National Union Patriotic Front-led government is affecting governance in general and in particular Harare municipality’s ability to handle the illegal street vending problem. While the paper essentially identifies political expediency as the major reason why a lasting solution is elusive in handling the illegal street vending problem, it acknowledges that there are broad reasons for its persistence. Consequently, the article demonstrates some of the reasons why illegal street vending is difficult to end using the conventional methods and provides some alternatives. 相似文献

AbstractIn 2011 a wave of revolutionary movements, the so-called Arab Spring, spread in the Middle East and North Africa. Libya was one of the most affected countries, ending Gaddafi’s dictatorship after an international intervention and a civil war. This paper assesses the effects that this revolution had on Libyan economy. The analysis is made by means of the synthetic control method. Our estimates for the 2011–2014 period show (i) a cumulative loss in the growth rate of per capita real GDP of 64.15%; (ii) a cumulative loss in per capita real GDP of 56,548 dollars; and (iii) a cumulative loss in the aggregate real GDP of 350.5 billion dollars. 相似文献

针对灾害现场应急指挥决策方案优选问题,提出了方案优选评价的可行性、时效性和安全性指标,应用模糊数学的相关理论构建了模糊综合评价的数学模型,采取专家调查打分法解决了方案评价影响因素的权重值及其评价等级的隶属度的确定问题,并采取加权平均算法对权重集A和影响因素评判隶属度矩阵R进行运算,得到的结果不仅反映了所有因素权值的影响,而且保留了单因素评判的全部信息,能够体现"模糊综合评价"的实质。 相似文献

This article explores gender and security sector reform (SSR) in Zimbabwe from 2008 to the present. It firstly postulates that the purpose of gender-sensitive SSR is to transform security services so as to enhance human security, as opposed to having an exclusive focus on state and territorial security. A comprehensive analysis of the policy and legislative framework governing gender and SSR at the global, continental, sub-regional and national levels will be presented, followed by the argument that efforts to reform the partisan and oftentimes non-professional tendencies of the security sector – especially the Zimbabwe Defence Forces, Zimbabwe Republic Police, Central Intelligence Organisation and Zimbabwe Prison Services – to promote democracy have met with firm resistance. However, gender-sensitive SSR has made significant headway in Zimbabwe since it is considered less threatening by the government. It should be noted, nevertheless, that gender-sensitive SSR has the potential to shift levels of professionalism and accountability within the sector as well as change attitudes to enhance security at the personal and communal levels. The process can gradually increase the percentage of women serving in the security sector. In conclusion, recommendations are made to broaden and deepen gender-sensitive SSR as the only viable alternative in the current political environment in Zimbabwe. 相似文献

以吸附后溶液中Cr3+质量浓度低于国家相关标准为目的,采用搅拌动态吸附的方法,研究投加量、吸附时间、吸附温度、pH值对吸附的影响,考察沸石粉对Cr3+深度吸附的条件。实验发现,在沸石粉投加量为1g/L的前提下,吸附时间为2h、温度为55℃、pH值为4~5时分别达到较好吸附效果。开展三因素三水平正交试验,得到深度吸附条件为:投加量1g/L、吸附时间2h、吸附温度35℃、pH=5,此时去除率达到99.7%。对深度吸附条件进行验证,发现在此条件下可以将Cr3+溶液的质量浓度由0.1mg/L降低至0.03mg/L;最后通过实验得出沸石粉对Cr3+的饱和吸附量为79.93mg/g。 相似文献
