In recent years, offering credit period by the supplier to the retailer has become a usual strategy. Hence, in the present work, an inventory model for noninstantaneous deteriorating items is framed considering money inflation and time discounting, where a permissible delay period is offered by the supplier as an alternative to price discount. Further, the salvage value associated with deteriorated units is considered, and the shortages allowed are partially backlogged. Focus is made on obtaining the optimal replenishment policy by minimizing the total inventory cost. This is achieved by developing mathematical theorems that determines the existence and the uniqueness of the optimal solutions. Moreover, computational algorithm is designed and illustrated using numerical examples and analysis. Various managerial insights obtained from the analysis are also highlighted.
