最佳化允收水準與總成本問題-以蝕刻片材為例

Abstract

目前台灣產業都必須降低生產成本來達到顧客滿意度，但顧客期望的不只是價格上的優惠，更在乎生產品質上的整體表現。因此在投入生產前，最先執行產生就是檢驗這項成本，若能在一開始就檢驗出供應商入料不合格品，即可降低產品入料生產後可能發生的報廢成本、重工成本等…，但實際上，經IQC執行抽樣檢驗時，就有可能發生誤判的機率。抽樣檢驗的結果判定為拒收，但實際上產品品質卻是好的批量，反之，檢驗結果判定為允收，實際產品品質卻是壞的批量。因此若能在檢驗時，修改檢驗方法來微調型一誤差與型二誤差發生的費用，期望總成本最小化。

For now, Taiwan industry must reduce production costs to achieve customer satisfaction, but customers also expect not just preferential price, but also care about the quality of production on the overall performance. Before it is often in the production of semi-finished, the first execution of the cost of the project is to inspect, inspect out first if the supplier nonconforming can reduce the cost of the product into the failure material production that may occur, failure costs, rework costs … In fact, when IQC perform sampling by, the chances of a miscarriage of justice likely occurred. Results of sampling for the rejection, but in fact it is a good batch of product quality, otherwise , the test results for acceptance, the actual product quality is bad batch. So if at the time of inspection, testing methods modified to adjust the occurrence of type I error and the type II error of cost, you can expect the total cost is minimized.
