進行可靠度試驗的目的是為了在產品的研發與製造的過程中，評價、驗證、保證或提高產品可靠度，以確保交貨之後，在規定的使用時間內及規定的使用條件下，能夠達到規定的可靠度指標並提供有關的數據；而加速壽命試驗是在物理與時間上，加速或加嚴產品退化的肇因，以較短的時間進行試驗，造成產品失效，據以估計產品的操作壽命，使產品做進一步的改良。台灣自來水公司為了確保水表計量的正確性，在水表檢定合格有效期間到期前會主動免費替顧戶更換水表，為了避免造成顧客使用上遇到麻煩，自來水公司會強烈要求供應商的產品品質，而電子水表中最重要的零件為電子水表之LCD顯示器。本研究以兩間供應商提供之電子水表之LCD顯示器作為研究對象，以高濕高溫執行加速壽命試驗，運用派克模型(Hallberg-Peck)估計電子水表之LCD顯示器可靠度相關參數，並使用R語言執行數據分析，探討出產品在正常使用下之平均壽命，最後藉由試驗結果選出最佳供應商。

The purpose of the reliability test is to evaluate, verify, guarantee or improve the reliability of the product in the process of product development and manufacturing to ensure that after delivery, it can be achieved within the specified use time and specified use conditions The specified reliability index and provide relevant data; and accelerated life test is physical and time, accelerate or tighten the cause of product degradation, test in a shorter time, resulting in product failure, based on the estimated product operation Longevity makes the product further improved. In order to ensure the accuracy of the water meter measurement, the Taiwan Water Supply Company will take the initiative to replace the water meter for the customer free of charge before the expiry of the validity period of the water meter verification. In order to avoid causing trouble for customers, the water supply company will strongly demand the quality of the supplier ’s products. The most important part of the electronic water meter is the LCD display of the electronic water meter. In this study, the LCD monitors of electronic water meters provided by the two suppliers were used as the research object. The accelerated life test was carried out with high humidity and high temperature. The Hallberg-Peck model was used to estimate the reliability parameters of the LCD monitors of the electronic water meters, and the language R was used. Perform data analysis, discuss the average life of the product under normal use, and finally select the best supplier based on the test results.
