當製造商的元件來自兩個供應商，且個別供應商的元件品質可能不一致時，在混合的比例已知的條件下，本論文採用元件壽命服從韋伯分配的假設，研究在逐步型一區間設限樣本之混合韋伯分配下的參數估計問題，使用 Metropolis-Hasting 馬可夫鏈蒙地卡羅演算法得到模型的參數估計的結果，並以蒙地卡羅模擬評估估計方法的成效。通過模擬結果得到在大樣本下，本論文提出的估計結果相對穩定。 When two suppliers supply components to a manufacturing company and the components from different suppliers could have different levels of quality, the mixed Weibull distributions is considered as the lifetime model of components. Moreover, an analytical Metropolis-Hasting Markov chain Monte Carlo procedure is proposed to estimate the model parameters. A simulation study is carried out to evaluate the performance of the proposed estimation method. Simulation results show that the proposed estimation method perform well with large samples.
