本文将文献[1,2]所给的最小平方逼近法推广应用于层次分析法中的群决策排序。文中对由多个判断决策者给出的多个不同的判断矩阵,提出通过求解群组判断矩阵最小平方偏差的方法得出判断矩阵的最佳排序和理想综合判断矩阵;通过对群组判断矩阵进行一致性讨论,据此又给出了一种用于群组判断矩阵排序的最小加权平方逼近法。理论分析和应用实例表明,应用最小平方逼近法和最小加权平方逼近法对群组判断矩阵进行排序是可行的和有效的。  相似文献

Early in 1904,Hadamard[1]showed the scale implicit function theorem of finitedimensions.Then it was generalized to infinite dimensions.In this paper a new proof of this theoremis given and the unique existence of the periodic solution for a class of ordinary differential equationsystems at resonance is obtained.  相似文献

In this paper, an approach to improving consistency of judgement matrix in the Analytic Hierarchy Process (AHP) is presented, which utilizes the eigenvector to revise a pair of entries of judgement matrix each time. By using this method, any judgement matrix with a large C.R. can be modified to a matrix which can both tally with the consistency requirement and reserve the most information that the original matrix contains. An algorithm to derive a judgement matrix with acceptable consistency (i.e., C.R. < 0.1) and two criteria of evaluating modificatory effectiveness are also given.  相似文献

In this paper we obtain the necessary and sufficient condition for the connec-tivity of the Cayley color graphs or the Cayley graphs to be equal to their minimum degree.The sharp lower bounds of connectivity of Cayley color graphs and the Cayley graphs arealso obtained. Our results generalize the previous results obtained in [1] to [3].  相似文献

为了解决传统粒子滤波器粒子退化与贫乏问题,提出了快速变异的遗传重采样粒子滤波算法.该算法将快速Metropolis-Hastings(MH)移动作为遗传算法的变异算子,使得快速变异算子与传统交叉算子、传统选择算子组合为一种新的粒子重采样算法.快速MH变异能对粒子进行移动,使得粒子的稳定分布为目标的后验概率密度分布.快速变异能有效解决一般变异算法易发散的问题,可以更快地提取到反映目标概率特征的典型粒子.实验证明,基于快速MH变异的遗传重采样方法可以快速提高粒子的多样性,避免粒子退化,减小跟踪误差.  相似文献
