Abstract
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.
