藉由動態可靠度模型可預測系統平均壽命，以此依據為評估系統設計之重要指標。一產品在設計結束，加工製造之前，其可靠度已大致決定，故欲擁有一高可靠度的系統，從設計階段著手乃其根本。本文藉由條件機率法與馬可夫鏈法對非等強度分負荷(k,n)系統進行分析，討論負荷相關等值失效率及負荷相關累積失效率之分負荷(k,n)系統，並以黃舉錐博士所提出之「分系統壽命相同」策略對其進行最佳負荷分配設計。以裕度觀點為考量，乃希望能爭取較多的緩衝時間以進行維護保養亦或更換等應用，故可選擇備用系統作為設計策略。最後，考慮在相同元件個數條件下之負荷相關等值失效率系統，評估其為備用系統設計時之可靠度變化與平均壽命，並透過黃舉錐博士所提出之效用因子與裕度因子觀點使系統比較更具意義。System MTBF can be anticipated from dynamic reliability model as a reference and important index to assess system design. Reliability of one product is generally defined prior to manufacture after design completion. Hence design phase is the commencement of a high reliability system. In this thesis, analysis to shared-load k-out-of-n:G system is performed in accordance with conditional probability method and Markov chain method. In order to discuss shared-load k-out-of-n:G system of load-dependent failure rate and load cumulative failure rate. As well as optimal load allocation design will be proceeded based on the “once a system fails it is better to have all its components fail simultaneously”strategy developed by Dr. J. J. Huang[6]. The purpose is to obtain more buffering time to carry out maintenance or replacement works. Therefore standby redundant systems can be one of the design strategy option in consideration of tolerance. Eventually, in considering of system load-dependent failure rate under the same component amount condition to assess the reliability variation and MTBF while performing its standby redundant system. Effectiveness factor and tolerance factor addressed by Dr. J. J. Huang[6] had been applied as well to make system comparison more meaningful.
