The present study was carried out to investigate Yang’s model by using an algebraic method (neither applying the first-order nor the second-order differentiations) to determine the optimal replenishment policy. The number of delivery and the integrated total cost is immediately provided by the proposed algebraic derivation as well. As a result, students who are unfamiliar with calculus may be able to understand the solution procedure with ease.
