逐步應力加速型一區間設限下之允收抽樣計畫 / Acceptance Sampling Plans under Step-stress Test and Type Ⅰ Interval Censoring Data陳信豪, Chen, Hsin-Hao Unknown Date (has links)
在壽命檢測試驗中,當我們因故或基於實驗上的方便無法連續觀察檢驗產品時,可以採用區間設限方式進行試驗,此外,對於許多長壽命的零件與產品,我們很難在試驗結束之前觀測到足夠的試驗單位死亡個數,此時可以採用加速壽命試驗的方式進行試驗,此種試驗方法可使受測的試驗單位提早故障,以有效地減少試驗所需的時間,並達到縮減成本的目的。本論文結合逐步應力加速試驗、型一設限以及區間設限,探討當產品壽命服從Rayleigh分配時,如何建立壽命檢驗計畫,在給定生產者風險與消費者風險下,求出壽命檢驗計畫所需的最小樣本數,以及判定貨批是否接受的壽命檢定臨界值,並將以上結果編製成表,以利實務界使用。 / In life test experiment we use interval censoring to complete it when we can not inspect the experiment units continuously due to some accidents or for convenience. Furthermore, it is difficult to obtain enough units of breakdown products for many long life components and products. At this moment we can adopt step-stress life test to proceed the experiment. Using this method we can make the test units breakdown early for reducing the time test needed effectively and save prime cost. In this thesis, acceptance sampling plans are established for Rayleigh lifetime data under step-stress and type I interval censoring scheme. The minimum sample sizes and the corresponding critical values of lifetime needed for test plans are found. Some tables are provided for the use of the proposed test plans.
