摘要


訂定最適製程目標值,對製造業而言是十分重要的課題。在產品製造過程中,管理決策者或工程師若為了節省製造原始物料成本,降低製程目標設定值,易使產品不符合顧客規格的機率提高;反之,提高製程目標設定值,雖然會降低不符合顧客規格產品的機率,但對於高原始物料成本或大量生產的產品而言,也易使成本提高、利潤減少。本文考量了再製成本等製程的經濟條件考量,建立期望利潤模式;本文並決定了「再製成本臨界值」;亦即,當再製成本大於此臨界值時,期望利潤將會減少,本文並將藉由範例說明我們的方法,及如何獲得最適製程目標值。

The determination of the quality target for a manufacturing process represents an intricate and fiscally vital decision. Although the quality characteristics of the finished product may satisfy consumer expectations when the process target is set high, the raw material and production costs necessary to maintain such high quality levels may prove prohibitively expensive. Conversely, while the manufacturer may avoid excessive production costs by setting lower process targets, the finished product's quality characteristics may not meet the customer's specifications. This study considers the rework costs in the expected profit function. This study also determines the ”critical value of rework”, in which when the rework cost is greater than this critical value, then the expected profit would be decreased. A method for identifying the optimal process target that reflects holding costs and rework costs is presented and illustrated by the example.
