摘要

本研究以美國軍規標準(MIL-HDBK-217F)、貝爾實驗室規範(Bellcore RPP)及中國大陸規範(Chinese Standard 299B)三種可靠度預估標準，探討在不同規範標準下，產品可靠度預估的差異及各種方法之優缺點，並以衛星通信船艦接收系統為案例說明闡釋之。本論文研究方法是透過設備失效率影響因子特性分析、產品敏感度分析及零組件影響設備之權重比較，以及評判說明預估值與實際使用值之差異原因，分析評估產品可靠度預估的應用價值。本論文在探討影響設備失效率之主要因子特性分析時，考慮之主要因子有品質因子、溫度因子及電氣應力因子。觀察得到在品質因子方面，MIL-HDBK-217F及Chinese Standard 299B對品質因子的定義較嚴謹；在溫度因子方面，Chinese Standard 299B對溫度因子定義最完整；在電氣應力強度因子方面，Bellcore RPP應用最便利。影響設備失效率之零件敏感度分析時，MIL-HDBK-217F規範中以環境因子的影響最大；Bellcore RPP中以電氣應力因子影響最大；在Chinese Standard 299B中是以環境因子影響最大。零組件影響設備失效率之權重比較時，MIL-HDBK-217F中開關裝置所佔權重最大(53.99%)，在Bellcore中IC晶片所佔權重最大(58.99%)，在299B中IC晶片所佔權重最大(39.64%)。本論文之研究成果希望提供業者產品後續研發生產之參考，以增快產品研發速度，提高產品可靠度。

The purpose of this research is to exploit the differences of product reliability predictions and to compare the advantages and disadvantages for three different standards and criteria, including the USA military standards, the Bell laboratory standards, and the Chinese reliability prediction standard. A shipboard satellite communication receiving system is used to study the difference among these three standards. The methodology adopted in this thesis includes: The characteristic analysis of the factors affecting equipment failure rates, the sensitivity analysis of parts, the weighting comparisons of the parts affecting equipments, and the evaluation explanation of the different reasons between the prediction values and practical application values. The main affecting factors considered quality, temperature, and electric stress. Both of the MIL- HDBK- 217 F and the Chinese Standard 299 B are more strict and concise for quality factor definitions. The Chinese Standard 299 B is more strict and concise for temperature factor definitions, and the Bellcore RPP is for electric stress factor definitions. The results of parts sensitivity analysis affecting equipment failure rates reveal that the most affected factors in the MIL- HDBK- 217 F, Bellcore RPP, and Chinese Standard 299 B are environmental, electric stress and environmental, respectively. In the weighting comparisons of the parts affecting equipment, we obtain switch devices (53.99%) in the MIL- HDBK- 217 F, IC chip (58.99%) in the Bellcore RPP, and IC chip (39.64%) in the Chinese Standard 299 B are the dominated weighting factors for the three standards. From this research, we hope the research results can be adopted by the manufacturer for the future research, development and manufacturing.
