    Abstract: This study discusses a deterministic EOQ model under conditions of permissible delay in payments. In many inventory systems suppliers offer some fixed credit periods to retailers for settling the accounts for the goods. This study explores a deterministic inventory model for deteriorating items with stock and time dependent demand for which the supplier permits a fixed trade credit period. In this study we assume that excess demand is partially backlogged. Finally numerical examples are given to elucidate the model.
