%0 Journal Article %T The effect of service constraint on EPQ model with random defective rate %A Yung-Fu Huang %J Mathematical Problems in Engineering %D 2006 %I Hindawi Publishing Corporation %R 10.1155/mpe/2006/79028 %X Chiu studied the effect of service-level constraint on the economic production quantity (EPQ) model with random defective rate. In this note, we will offer a simple algebraic approach to replace his differential calculus skill to find the optimal solution under the expected annual cost minimization. %U http://www.hindawi.com/journals/mpe/2006/079028/abs/
