摘要
基于模糊理论 ,采用三角模糊数来表示 AHP判断矩阵中的元素大小 ,根据α水平截集和乐观指标λ ,进行模糊区间运算并得出模糊判断矩阵的特征值 ,从而提出了机电系统综合评判的模糊 AHP法 ,并给出了该方法的工程应用算例。结果表明 :本文方法科学合理、简单、实用 。
Fuzzy analysis hierarchy process (Fuzzy AHP) for evaluation of electromechanical system is presented in this paper. The method uses triangle fuzzy numbers to establish judgement matrix, and to improve the unbalance problem of AHP's judgement matrix. The eigenvalue of fuzzy judgement matrix is given through the fuzzy interval arithmetic based on a level sets and optimistic index λ, then we analyse and evaluate electromechanical system according to the eigenvalue. The example shows that fuzzy AHP method for electromechanical system is feasible.
