本文讨论了以分层法进行中药药效评价时权重设立的问题，主要由以下几部分组成: 1．建立递阶层次结构；2．构造两两比较判断矩阵；3．计算单一准则下元素的相对权重；4．计算各层元素的组合权重。由于中药作用具有多途径、多靶点的特性,因此评价过程中权重的设立就占有重要位置。它直接影响对被评价对象药效作用的评判。全面解决中药作用多途径、多靶点药效学评价的数学方法,客观量化的评价中药的综合药效，是中药现代化进程中一个值得研讨的命题。

This article discusses the establishment of weight in the assessment of TCM effectiveness by the method of stratification, which is composed of the following parts: （1） the establishment of hierarchical strata structure, （2） the construction of pair wise comparison decision matrix, （3） the computation of the relative weight of elements under a single norm and （4） the computation of the combined weight of elements in all the strata. The establishment of weight plays a significant part in the assessment since the functions of traditional Chinese medicine is characterized by multi - ways and multi - targets, which is able to directly influence the judgement of the effectiveness of assessed medicaments. It is a subject worthwhile being studied in the progress of the modernization of TCM to generally settle down the mathematic method for the assessment of TCM effectiveness with multi - ways and multi - targets and to assess the comprehensive effectiveness of TCM by means of objective quantization.
