【摘要】 关联算子和分辨系数是灰色关联分析中的2个重要参数.结合地区电网建设规模评估应用背景,以抗干扰性和差异最大化为基本原则,提出确定该2参数的系统方法.对原始序列施加扰动以检验关联算子抗干扰能力,以“区间覆盖率”和“差异度”测度关联算子对原始序列差异程度的影响,实现对关联算子性能的全面评价;按整体性和抗干扰性要求及差异最大化原则确定最佳分辨系数.提出的关联算子和分辨系数确定方法理论严谨,实践表明简便有效,使地区电网建设规模评估的原理和方法更加科学完善.更多还原

【Abstract】 The grey relation operator and the distinguishing coefficient are two significant parameters in grey relational analysis(GRA).Under the application background of distribution network building size evaluation, the authors systematically investigate the influence of grey relation operator and distinguishing coefficient on the results obtained by GRA.In order to meet the needs of anti-disturbing ability and optimizing discrimination,the authors proposed the criteria and some practical methods to determine grey relation operator and distinguishing coefficient based on the strict mathematical formulation.The simulation result shows that the criteria and practical methods are reasonable and efficient.更多还原
