Kappa系數(shù)在卷煙外觀檢驗一致性評價中的應(yīng)用

摘" 要：煙草行業(yè)對于卷煙成品的外觀質(zhì)量具有較高的要求，卷煙外觀方面檢驗仍主要依靠人工目測，但是目前卷煙物理檢驗師考評外觀檢驗一致性檢驗缺少直觀量化的數(shù)理評價指標(biāo)及方法，因此提出Kappa系數(shù)在卷煙外觀檢驗一致性評價中的應(yīng)用思路。以GB 5606.3—2005《卷煙 第3部分：包裝、卷制技術(shù)要求及貯運》中的5項箱裝外觀質(zhì)量指標(biāo)，7項條狀裝外觀質(zhì)量指標(biāo)，13項盒裝外觀質(zhì)量指標(biāo)，13項煙支外觀質(zhì)量指標(biāo)為研究對象，設(shè)計3個方案，選擇5名具有從業(yè)資質(zhì)和工作經(jīng)驗的卷煙檢驗員進(jìn)行外觀檢驗一致性試驗，并使用Minitab軟件分析檢驗員的Kappa值，重點研究樣品設(shè)計中外觀質(zhì)量指標(biāo)有定量要求和無定量指標(biāo)僅為定性描述的樣品占比對Kappa值的影響。結(jié)果表明，樣品方案中有定量要求的指標(biāo)樣品占比多時，方案越簡單，檢驗員的Kappa系數(shù)越大，無定量要求僅為定性描述要求的指標(biāo)樣品占比多時，方案越難，檢驗員的Kappa系數(shù)越小。Kappa系數(shù)一致性檢驗可直觀量化檢驗員外觀檢驗的重現(xiàn)性、再現(xiàn)性、準(zhǔn)確性等指標(biāo)，有利于質(zhì)量風(fēng)險管控。

Abstract： The tobacco industry has higher requirements for the appearance quality of cigarette products， and cigarette appearance inspectionmainly depends on manual visual inspection， but at present， cigarette physical inspectors lack intuitive and quantitative mathematical evaluation indexes and methods for external light inspection consistency inspection， so the application idea of Kappa coefficient in cigarette appearance inspection consistency evaluation is put forward. Taking 5 items of package appearance quality index， 7 items of strip package appearance quality index， 13 items of box appearance quality index and 13 items of cigarette appearance quality index in GB 5606.3-2005， Cigarettes， Part 3： \"Packaging， Rolling Technical Requirements and Storage and Transportation\" as the research object， three schemes were designed， and 5 cigarette inspectors with professional qualifications and working experience were selected for appearance inspection consistency test. Using Minitab software， this paper analyzes the examiner's Kappa value， focusing on the impact of the proportion of samples with quantitative requirements and no quantitative index only qualitative description on the Kappa value in sample design. The results show that when there are more quantitative index samples in the sample scheme， the simpler the scheme is， the larger the Kappa coefficient of the inspector is， and the more difficult the scheme is， the smaller the Kappa coefficient of the inspector is. The consistency test of Kappa coefficient can directly quantify the reproducibility， re-occurrence and accuracy of the inspector's vision， which is beneficial to quality risk control.

在卷煙成品質(zhì)量的評價指標(biāo)中，目測為檢驗中的重要手段。人眼目測檢驗精度有限且存在差異，檢驗員外觀檢驗一致性評價亟需一種直觀科學(xué)量化的數(shù)理評價指標(biāo)及方法來評價檢驗員的準(zhǔn)確性、穩(wěn)定性和人員之間的一致性。……
