| Abstract: |
| In this paper, inventory policies problem for deteriorating goods is studied under permissible delay in payments correlated with order quantity. When deteriorating rate is very low, by using the second-order Taylor expansion, matrix theory and optimization techniques, we obtain the optimal out-of stock time, the optimal ordering cycle and the optimal retail price; when deteriorating rate is relatively large, we provide an interior point algorithm for acquiring the retailer's optimal decision marking solution. Finally, a numerical experiment is to illustrate and discuss the influence of parameters on the optimal decision marking. |
