一种计算主观权重系数的新算法及其C语言实现

One New Calculating of the Subjective Weight Coefficients and C-language Realization

如何合理地确定各评价指标的主观权重是综合评价理论和实际应用中的一个关键问题。为此提出了利用心理学中的配对比较法来确定各评价指标权重的新思路。本文给出了用配对比较法计算主观权重的原理和算法，并用c语言编写程序对教学效果评价指标体系中各指标的权重进行进行计算，取得了较好的效果。该方法原理清楚，步骤简单，计算结果较为客观，在综合评价中具有很好的推广应用价值。

How to reasonably determine the subjective weight coefficients of every factor is a key problem in comprehensive assessment.One new approach of paired comparison is brought forward to decide the weight coefficients of every assessment factor.The theory, method and procedure are discussed.And the new approach is easy to understand and very simple to be implemented.The result is rather objective,and shows great potential in co mprehensive assessment.
