Here an inventory control model of a decaying item with zero lead time is studied. Two mathematical models under different assumptions are developed.In the first model deterioration rate is time-dependent and demand rate is price sensitive while in the second model deterioration rate is constant and demand rate is time- and price-dependent. Aim of this research is optimizing total cost by deriving decision variables such as dispatch cycle length, order quantity and wholesale price. To optimize the total cost a shipment group dispatching policy is used. %U https://scientiairanica.sharif.edu/article_4449_516efb2cb04c9dfd8e04908af1019019.pdf
