An Inventory Policy for Partial Backorders Case with Interest Rate

이자율(利子率)을 고려한 부분(部分) 부재고(負在庫) 재고(在庫) 모형(模型)에 관한 연구

In this paper, a deterministic EOQ model with interest rate in which a proportion (${\beta}$) of the demand is backlogged and the rest (1-${\beta}$) is lost. The optimal order quantity is derived and the corresponding average cost is obtained, Sensitivity analysis is performed to sec the influence of interest rate on the optimal order quantity and the average cost. Finally a numerical example is given in which optimum quantities of the model developed in this study and those of the conventional EOQ model are compared.
