一种新的机电系统模糊评判方法

摘要

给出了一种新的机电系统模糊评判方法。该 方法允许系统指标所包含的每一个子项目具有不同的可以用三角模糊数表达的权重，综合得 出用三角模糊数表达的系统指标的模糊分值，再根据α水平截集和乐观指标λ进行模糊 区间运算，得出系统的综合模糊评判结果。实例表明：本文方法科学合理、简单实用，具有 一定的工程应用价值。%A new fuzzy analysis hierarchy process (fuzzy AHP) of the system is presented in this paper. The method allows that the sub-items of the system indexes have the different weights presented by the triangle fuzzy numbers, uses the weighting method to get the total fuzzy evaluating value of the system. The comprehensive evaluating result is given through fuzzy interval arithmetic based on α level sets and optimistic index λ. The example shows that new fuzzy AHP method of the system is scientific and reasonable, and has important value of engineering application.
