Method for determining multi-point production cigarette standard samples by membership function

Abstract

The invention discloses a method for determining multi-point production cigarette standard samples by a membership function. The method comprises the following steps: (1) respectively detecting quality indexes of the multi-point production cigarette samples; (2) normalizing the numerical value detected in the step (1) by adopting a membership function; and (3) respectively substituting the index values of the cigarettes produced at each point, which are obtained by the normalization of the membership function in the step (2), into the following formula for calculation, m=X11*0.20+X12*0.05+X13*0.05+X21*0.25+X22*0.05+X23*0.05+X31*0.35; and (4) determining the highest M value of the cigarettes produced at each point as a cigarette standard sample according to the step (3). The method providedby the invention is more objective, scientific and reliable to determine the multi-point production of the cigarette standard sample.

Description

technical field [0001] The invention belongs to the technical field of tobacco production, and in particular relates to a method for normalizing cigarette indexes and corresponding weighting by using a membership measurement function, quantifying the comprehensive quality score of cigarette samples, and determining multi-point production cigarette standard samples. Background technique [0002] Under the layout of tobacco brand development of big brands, big enterprises and big markets, multi-point production and cooperative production of cigarettes of the same specification have become the mainstream way of large-scale brand development in recent years. What cannot be ignored is that the physical, smoke, and sensory quality indicators of cigarettes of the same specification vary to varying degrees in multi-point production. For this reason, the tobacco industry regularly carries out the determination of cigarette standard samples. The determination of cigarette standard sam...

AI Technical Summary

Problems solved by technology

There are many deficiencies in the determination method of the cigarette standard sample in the prior art: 1. Emphasis on the sensory quality score of the sample, and less consideration of indicators such as physics and smoke, resulting in relatively poor physical indicators, smoke, etc. corresponding to the cigarette standard sample. large fluctuations

2. The U-turn rate of cigarettes and the rate of sticky notes are not considered. With the improvement of testing technology and the continuous improvement of the testing standard system, the quality standard requirements of cigarette standard samples need to be updated and improved. Insufficient key quality indicators considered in cigarette reference sample determination process

3. It is common for smokers in the current cigarette standard sample determination process to rate their sensory quality in favor of the target production site, such as the sample from the first manufacturer of the product, and the objectivity of selecting cigarette standard samples is insufficient.

4. The current national standards, industry standards and norms for the quality scoring items involved in standard samples of cigarettes are all qualified and roughly graded, without quantitative scoring; in the context of the gradual increase in brand cooperative production sites, there are often multiple The situation where the scores of the production points are the same or the difference is small, resulting in the need for multiple rounds of paired comparison tests or three-point test sensory quality evaluation, which increases the workload of the evaluation accordingly

Due to the above-mentioned deficiencies in the current determination method of the multi-point production cigarette standard, the determination result of the current cigarette standard sample cannot represent the sample of the brand and specification with the best comprehensive quality, and the cigarette standard sample cannot be used to guide the multi-point processing cigarette manufacturing process and formula. , Standard functions of product maintenance
