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.]]>Banerjee, A.,198617292311Ben-Daya, M., M. Darwish and K. Ertogral,2008185726742Cardenas-Barron, L.E.,200170289292Chou, C.L., Y.F. Huang and H.F.
