Z比分数-模糊AHP评价模型在卷烟成品实验室检测能力评价中的应用

为解决Z比分数法只能对卷烟成品实验室单个指标进行分析评价问题,将Z比分数、层次分析法(Analytic Hierarchy Process)与模糊综合评价法相结合,建立了Z比分数-模糊AHP评价模型。评价分为8个步骤:构建卷烟成品实验室评价指标体系,利用AHP确定各指标权重,将实验室每个样品的指标检测值转化为Z比分数(Z,ZB,ZW),利用模糊评价方法建立评语集和对应的分数集,把每个指标各样品Z比分数在评语集各等级所占比例作为隶属度,形成模糊判断矩阵,最终得到实验室物测、烟气以及综合检测能力评价得分及排序。以10个实验室为例验证了该模型的综合评价能力。结果表明,该综合评估方法适用于多样品和多指标的实验室比对综合能力评价,可以整体评价实验室物测、烟气和综合检测能力,并可分析查找存在问题的指标,为卷烟成品实验室的优化改进及提升检测能力水平提供了支持。 

Application of Z Score-Fuzzy AHP Model to Evaluation of Testing Capability of Cigarette Laboratory

A Z score-fuzzy AHP model was established by combining Z score, AHP(Analytic Hierarchy Process) with fuzzy comprehensive evaluation method. The evaluation process involved eight steps: establishing a cigarette laboratory evaluation index system, determining the weight of each index with AHP, converting the test results of each index for each sample into Z score(Z, ZB, ZW), establishing a set of evaluation term and a score set with fuzzy evaluation, taking the proportion of Z score of each index for each sample in the evaluating term set as membership degree, forming fuzzy judgment matrix, and finally obtaining the score and rank of cigarette laboratories in terms of physical property testing, smoke analysis and overall testing capability. The established model was verified by taking ten cigarette laboratories as examples.The results showed that this method was suitable for evaluating the testing capability of a cigarette laboratory concerning multi-sample and multi-factor, it could evaluate the physical testing, smoke analysis and overall testing capabilities of a laboratory and find out the indexes which might be problematic, to provide a reference for optimizing and improving the testing capability of the laboratory.
