隨著時代的變遷,科技進步的速度也越來越快,技術、儀器設備、原物料等不斷創新和改善,帶動了社會的發展,也影響消費者的生活。在現今社會中,消費者生活水準提高,再加上消費意識抬頭,消費者購買商品也由價格導向慢慢轉變為品質考量。允收抽樣為統計品質管制工具,可藉此提供生產或消費者判斷貨批品質水準是否滿足自身需求,驗收抽樣計畫可分為兩大類一類為計量型抽樣計劃(Variable sampling plan)另一類為計數型抽樣計劃(Attribute sampling plan)。
本研究重點著重在改善重複抽樣計畫中可能會抽樣無限多次的情況,一般重複抽樣計畫會對同一批次貨品進行抽樣,直到能夠做出執行決策還會結束,但可能會導致抽樣成本及時間成本的浪費,尤其當供應商製程能力較為一般時,更可能發生此情況。因此,本研究目標為在限制式的條件下,擁有高機率完成抽樣之最小平均樣本數。最後在相同參數條件下,將本研究結果與單次抽樣計畫及傳統重複抽樣計畫,將三者抽樣計畫進行相互比較。
經研究發現,無論是否擁有限制式,重複抽樣計畫的決策效率優於單次粥樣計畫。而傳統的重複抽樣計畫與有限制重複抽樣計畫在相同參數條件下,有限制重複抽樣計畫的抽樣樣本數會略大於傳統的重複抽樣樣本數,藉由抽樣樣本數略微增加,卻可以在有限抽樣次數內有高的完成抽樣機率,相信以決策者角度來觀察,增加小量的抽樣樣本數,卻可以減少檢驗時間及檢驗成本,以達製程管制之目標。
With the changes of the times, the speed of scientific and technological progress is getting faster and faster, which drives social development and affects consumers' lives. Today the improvement of living standards and the rise of consumer awareness. When the consumers buying products gradually changed from price-oriented to quality-oriented considerations. Acceptance sampling is a control tool of statistical quality, which can be used to provide producers or consumers the ability to judge whether the quality level of the batch meets their own needs.
The research focuses on improving the situation that repeated sampling many times. In generally, repeated sampling plans will sample the same batch of goods until an execution decision can be made, but it could lead to sampling costs and waste of time. Therefore, the goal of this study is to have the minimum average number of samples with a high probability of completing sampling under restrictive conditions.
The report show that the decision-making efficiency of the repeated sampling plan is better than that of the single sampling plan, regardless of whether there is a restriction or not. Under the same parameter conditions, the number of sampling samples of the limited repeated sampling plan will be slightly larger than the number of traditional repeated sampling samples. By slightly increasing the number of sampling samples, it could result in a high probability of completing the sampling within the limited number of sampling times. It is believed that from the perspective of decision makers, the study show an new idea for increasing the small number of sampling samples can reduce the time of inspection and cost of inspection to achieve the optimization goal of process control.
