中文摘要 | 如何決定一確切的壽命分配來擬合一組產品壽命的可靠度資料,是可靠度工程師 常面臨之決策問題。對數常態分配與韋伯分配常被考慮用在一個非負值隨機變數的非對稱 型分配的情形上;而對於高可靠度產品來說,其壽命分配資料大都會是這兩種分配之其一。 對於完整的加速壽命試驗資料,本文主要是探討三種有關對數常態分配與韋伯分配之分類 法則,並利用S-Plus程式來模擬,分別為這三種檢定方式產生一個所需要的臨界值與檢定力 的表格。如此可以這分出這三種分類法則採用的檢定統計量顯現出不同的檢定能力,而且 可以在使用的便利性上採用最為適當的檢定統計量來作為選擇確切分配的工具;最後, 文中並將舉實際上的以及模擬出來的資料範例來說明分配選擇的問題。 |
英文摘要 | The reliability engineers often face on the decision problem about how to decide the suitable life distribution to fitting the reliability data of product life. Log-Norma1 distribution and Weibul1 distribution are often considered to use in non-symmetry distribution of non-minus random variable. The data of life distribution could be one of both of them. For completed accelerated life test data, the study explored three discrimination rules and simulated the tables of critical values and power by using S-Plus program within the referred distributions. Using the test statistics of these three discrimination rules could appear different test power and could be adopted as a suitable tool in convenience use. Finally, this study took the practical and simulated data as examples to describe the problem of distribution choice. |
