Quality homogenized evaluation method for multi-spot produced cigarette products and difference index screening method

Abstract

The invention discloses a quality homogenized evaluation method for multi-spot produced cigarette products and a difference index screening method, which belong to the field of cigarette quality homogenized evaluation. The method is improved on the basis of the prior art. In the method, a lower limit which can be accepted by a main plant, namely a 6 or 3 sigma lower limit is calculated by using n index detecting results according to a Shewhart control chart theory; on the premise that the products are qualified in routine examination, the homogenized evaluation is performed between plants and the main plant or among the plants by using the Euclidean similarity coefficient matrixes of the plants; and by comparing and analyzing the inter-index variation coefficients of one couple or a plurality of couples of plants with the highest Euclidean similarity coefficients with the inter-index variation coefficients of one couple or a plurality of couples of plants with the lowest Euclidean similarity coefficients, the indexes are screened according to the condition that the absolute value of the difference of the variation coefficients is more than or less than 1 percent, and the screened indexes are the indexes which highly influence the quality difference of the products of the different plants. The method has the advantages of high operability and comprehensive and accurate detecting result, and is novel.

Description

Technical field: [0001] The invention relates to a multi-point production cigarette product quality homogenization evaluation method and the screening of difference indexes, belonging to the field of cigarette quality homogenization evaluation. Background technique: [0002] The so-called product homogeneity means that the quality of different batches of products tends to be consistent, and the quality of products of the same brand and specifications produced by different manufacturers tends to be consistent. At present, with the merger and reorganization of Chinese cigarette companies and the acceleration of the integration and expansion of cigarette brands, more and more cigarette brands have a realistic need for multi-point processing. The homogenization of product quality of cigarette brands under the conditions of remote processing and multi-point production has become an important topic of concern to the industry and an urgent problem to be solved by many cigarette com...
