AHP法改进及其在目标威胁等级评估中的应用 总被引:4,自引:1,他引:3
目标威胁等级评估有利于合理分配战场资源,进行科学的攻防决策,既能更好保存自己,又可有打击敌人。应用模糊综合评判和成对比较法构造判断矩阵,改进了层次分析法(AHP法),提高了判断矩阵的准确性和科学性。采用改进后的AHP法评估威胁水下潜艇生存的海面和水下目标,得到了目标威胁的量化结果。改进后的AHP法可用于其它类型目标的威胁等级评估,为进一步提高评估的准确性,模糊综合评判时专家评分权值可取不同值,但判断矩阵的特性有待进一步研究。 相似文献

基于主成分分析法的目标威胁评估 总被引:4,自引:0,他引:4
为提高防空作战指挥员对空中来袭目标实施火力分配的量化决策水平,本文提出了基于主成分分析法的目标威胁评估模型及方法。主成分分析法在将原始变量转变为主成分过程中,同时形成了反映主成分的权数以计算综合评价值,这样在指标权重选择上克服了主观因素的影响,客观反映了各指标因素间的现实关系。通过引入实例,对来袭空中目标进行多指标综合评价,根据综合评估值对各批目标威胁进行排序,所得结果合理且符合客观实际,切实为防空作战指挥员科学合理地实施火力分配提供了数据支持和科学依据。 相似文献

This article investigates how US national security planners have envisioned the emerging strategic environment during the early twenty-first century and evaluates how their perceptions of this strategic environment have changed during these years. This conceptual evolution can be seen in how defense planners define threats, identify defense priorities, and design security strategies. Five key strategic planning documents serve as the basis for this analysis and illustrate significant shifts in how the US government has envisioned its own security requirements as well as the context within which its strategic vision will need to be realized. These planning documents are: (1) Joint Vision 2020, (2) the Bush Administration's 2002 National Security Strategy of the United States, (3) the Obama Administration's 2010 National Security Strategy, (4) US Strategic Defense Guidance entitled Sustaining US Global Leadership: Priorities for 21st Century Defense, and (5) the US Chairman of the Joint Chiefs of Staff's Capstone Concept for Joint Operations: Joint Force 2020. 相似文献
