隨著科技的快速發展，產品的可靠性大幅的提升，然而，傳統的壽命測試所能夠在短時間內收集到的資訊非常有限，因此需要更有效率的方法來獲得關於產品壽命的資訊。如果產品存在一個品質特徵與其壽命有關，且會隨時間的增加而漸漸退化，並使用更嚴苛的測試條件加速產品失效，利用此退化路徑來估計產品之壽命資訊，稱為加速退化試驗，此外，過去學者提出了將壓力水平從最低到最高逐步提升的Step-stress 加速退化測試（SSADT），能夠用於縮短測持續時間和減少所需樣本量。
當買方向生產者訂購了一批產品時，生產者需要透過檢驗的方式來判斷產品的好壞，以確定是否符合買方所指定的可靠性要求。然而，如果採取全部檢驗的方式，將會耗費大量的時間和成本，因此採用隨機抽取一定比例的樣本的驗收抽樣方式，將會是更有效率的方法。但由於產品的更新速度非常快，無論是生產者還是消費者都無法忍受長時間的驗收抽樣。因此，建構一個在較為嚴苛環境條件下的加速退化抽樣計畫是非常必要的。
由於Wiener退化過程已被廣泛應用於退化建模和可靠性分析，因此本研究建立一個假設產品退化路徑服從Wiener過程的Step-stress退化測試抽樣計畫，以最小化允收標準檢定統計量的漸進變異數為目標，在滿足預算下求得最佳的樣本量及測量次數，並同時考量消費者風險與生產者風險，訂定允收標準判定是否允收貨批，最後利用操作特性(OC)曲線，來探討其最佳SSADT抽樣計畫的判別能力。

With the rapid development of technology, the reliability of products has been greatly improved. However, the information that can be collected in a short period of time by traditional life testing is very limited. In the past, scholars proposed a Step-stress accelerated degradation test that gradually increases the stress level from the lowest to the highest, which can be used to shorten the test duration and reduce the required sample size.
When the buyer orders a batch of products from the manufacturer, the manufacturer needs to judge whether the product meets the reliability requirements specified by the buyer through inspection. However, it will consume a lot of time and cost if the method of all inspections is adopted, so it will be more efficient to adopt the method of acceptance sampling.
Therefore, this study establishes a Step-stress degradation test sampling plan assuming that the product degradation path obeys the Wiener process, with the goal of minimizing the asymptotic variation of the acceptance standard test statistics, and obtaining the optimal sample size and Measure the number of times, and consider consumer risk and producer risk at the same time, set acceptance criteria to determine whether to accept the batch, and finally use the operating characteristic curve to explore the discriminant ability of the best SSADT sampling plan.
