基于Fuzzy ANP方法的关天经济区人才竞争力评价模型研究
关天经济区 人才竞争力 FuzzyANP评价法
2014/5/29
网络分析法(ANP)是一种能够有效处理复杂决策问题的多准则决策方法，然而，现有ANP文献在综合集成收益、机会、成本、风险(统称为BOCR)评价值时可能因评价值之间的不匹配而得出错误的方案排序结果和绩效表示。为克服上述缺陷,基于ANP法，结合三角模糊数对关天经济区人才竞争力进行评价，研究其指标之间的内在联系，更多地还原关天经济区人才竞争力现状并预测其发展。运用三角模糊数网络分析法（FuzzyANP...
针对现有背景抑制算法未能有效抑制背景而导致目标检测率低的问题，提出了一种基于模糊自适应共振理论（fuzzy adaptive resonance theory, FuzzyART）神经网络的弱小目标检测算法。首先,采用FuzzyART神经网络结合Robinson 警戒环技术，建立自适应局部空间背景模型，并以此分析像素点的背景模糊隶属度来抑制背景杂波；然后依据目标与残留背景杂波的空间特征采用模板...
