Application of a robust statistics based fuzzy comprehensive evaluation method in quality assessment between coal property laboratories
摘要
将稳健统计分析中的能力统计量Z比分数与模糊综合评价相结合
建立了Z比分数-模糊综合评价模型。该模型可建立一组用于多因素集中所有元素的模糊隶属度函数
以进行整体判断和描述
降低了运算复杂度。以某烟煤为检测对象
对34个煤质实验室检的测结果进行分析
结果表明
Z比分数-模糊综合评价模型克服了稳健统计分析和模糊综合评价的不足
适用于多因素集、多指标集的煤质实验室检测能力比对。
Abstract
Combining the Z-score from the robust statistics analysis method with fuzzy comprehensive evaluation(FCE)method
a Z score-fuzzy comprehensive evaluation model was established. This model is applied to a case study in ability evaluation of coal labs.The test result was transferred into Z scores
then converted to a fuzzy membership function
thus to perform a fuzzy comprehensive evaluation(FCE)on the satisfaction degree of the multi-variables to evaluate the laboratories' testing ability.Analysis on detection results of 34coal labs indicated that
the Z scorefuzzy comprehensive evaluation model can conduct an overall judgment and evaluation on labs
overcome the shortcoming that the RSA method can only deal with single factor problems and that the conventional methods have a large computational complexity
which can be applied in laboratory ability test with multi-factor set and multi-index set.
