Abstract
自從1980年代以來,田口式直交表實驗計算法被廣泛應用於產品與製程設計以提昇產品之品質。本文應用田口式直交表實驗,配合統計分析與模擬方法,對批量再訂購點存貨模式的決策參數進行穩健設計,以求達到降低存货成本的目的。爲了提昇批量再訂購點摸式的功能,本文首先構建改良型的批量再訂購點模式(具有四個決策參數);然而,一般存貨模式的數理解法不易求得這個新模式的參數,所以本文應用田口式實驗計畫法來決定改良型批量再訂購點摸式的決策參数。因爲田口式參數設計的過程已經考慮了影響存貨系統運作的雜訊效應,所以設計得到的結果具有穩健性,使系統能夠抵抗外界商場環境的衝擊,讓輸出更穩定(變異最小),從而降低存貨成本。文中舉一範例說明田口式參數設計之實驗及求解過程。在此範例中,對因子間的交互作用進行分析後,克服了確認實驗失敗(再現性不佳)所造成的困擾,使田口方法在確認實驗失敗後仍能找到理想的參數水準組合以降低存貨成本。Keywords
