摘要
本文从多指标综合评价方法基本原理上出发,对指标体系的构造原则和方法以及目的做了详细论述,在这基础上对指标的无量纲化、权重系数和指标综合值的确定提出了新的方法和建议。
评价方法的改进方面:在灰色关联度综合评价中,本文考虑到评价指标的相对重要性,引入了权数,避免了仅凭借关联度系数的简单平均值来排序,使得评价结果更加准确、客观;引入了系数100,使得评价结果变为百分制,使得灰色关联度评价方法更合理、更实用。
评价方法的创新:采用“0~1”评分法,避免了指标赋权的自相矛盾;引入系数9,实现了0~1评分与九分位比例刻度的顺利转换,尽量减少了主观赋权法对指标权重的影响,提高了权数确定的客观性和可操作性,使得评价结果更加客观。

ABSTRACT
This article from the many indexes prehensive evaluation method based on the basic principle of the construction of the index system of principles and methods and purpose do detail, in the basis of the index dimensionless, weight coefficient and indexes prehensive value puts forward a new method to determine the and Suggestions.
Evaluation method improvement aspects: in prehensive evaluation of grey correlation, this paper consider the relative importance of evaluation indexes, we introduce the weighted function, to avoid the correlation coefficient of only with simple average for sorting, makes the evaluation result more accurate, objective; Introducing the coefficient, makes the evaluation results of 100 to points, improving the gray relational degree evaluation method is reasonable and practical.
The innovation of the evaluation method to use "0 ~ 1" evaluation method, to avoid the weighting of contradictions: Introducing coefficient realize the 9,bring about 0 ~ 1 score and nine points a proportion of the smooth transfer scale, try to reduce the subjective method to the influence of the index weight, improve the rights to determine the objectivity and operability of the evaluation result, make more objective
