This paper uses a new method, modified quadratic-geometric mean inequality, to derive the optimal EOQ model with defective items and known price increase when the special order can be placed at the regular time for replenishment. This study also uses 100% inspection policy and the known proportion of defective items is removed prior to storage after the screening process. The method is very simple to derive the optimal EOQ model without derivative.
