An Economic Two-Sided Screening Procedure Using a Correlated Variable with Multi-Decision Alternatives

다 결정 대안을 갖는 대용특성을 이용한 경제적 양측 선별검사방식

For situations where there are several markets with different profit/cost structures, an economic two-sided screening procedure using a correlated variable is developed. It is assumed that the performance variable and the screening variable are jointly normally distributed. A profit model is constructed which involves selling price, cost incurred by imperfect quality, and screening inspection cost. Methods of finding the optimal screening procedure are presented and numerical examples are given.
