  • 允收抽樣一直是工業中廣泛運用的統計品質管制技術之一,當前的製造環境能夠大量批次的產品,在這個情況下,現存的單一抽樣計畫可能無法滿足生產者與消費者的需求,本論文提供了抽樣計畫的替代方案,像是專用單一屬性抽樣計畫、基於雙重允收標準的抽樣計畫和適用於常態與非常態分配的獨立混和抽樣分配, 研究目標計畫的執行並與現有計畫互相比較。本研究的績效指標包括樣本大小和抽樣計畫對於不符合單位之區分能力,針對零膨脹負二項分配,重新遞交了單一樣本計畫、重複性群組之抽樣計畫及多重依賴性之抽樣分配,而多重依賴性抽樣分配優於重新遞交之樣本計畫、重複性群組抽樣計畫和現存單一屬性之抽樣計畫,針對常態與膨脹型柏拉圖分配(Pareto distributions),提出了基於雙重允收標準之抽樣分配,而此雙重允收標準之抽樣計畫優於單變量樣本計畫,具有邊際品質之獨立混合抽樣計畫優於沒有邊際品質及雙變量之抽樣計畫,而在擬議計畫中呈現良好的績效以確保滿足顧客的需求。此篇論文的說明案例是基於已發表論文和模擬資料所提供的真實數據,說明所提出的抽樣計畫的績效。


    Acceptance sampling has been one of the widely used statistical quality control techniques enabling to ensure quality of industrial products. Due to the production of large size of lots in the current manufacturing environments and the various distributions of quality attributes, the traditional attributes and variables sampling plans may not be suitable for satisfying producer and consumer requirements. This dissertation presents alternative sampling plans such as special purpose single sampling plans by attributes, sampling plans based on dual acceptance criteria and independent mixed sampling plans that are suitable for normal and non-normal distributions. The performance measures such as sample size and the discriminating power of sampling plans are used to compare the proposed sampling plans with existing sampling plans. Resubmitted single sampling, repetitive group sampling and multiple dependent state sampling plans have been proposed for zero-inflated negative binomial distribution. Multiple dependent state sampling plan outperforms the resubmitted sampling plan, repetitive group sampling plan and existing single attributes sampling plan. Sampling plans based on dual acceptance criteria are proposed for normal and inflated Pareto distributions. The sampling plans based on dual acceptance criteria performs better than single variables sampling plans. Independent mixed sampling plan with marginal quality shows better performance in terms of sample size and discriminating power compared with the one without marginal quality and double variables sampling plan. The proposed plans show better performance to ensure the satisfaction of producer and customer needs. Illustrative examples are provided to illustrate the performance of the proposed sampling plans.
