‎This paper proposes a multi-supplier multi-product inventory model in which the suppliers have unlimited production capacity, allow delayed payment, and offer either an all-unit or incremental discount. The retailer can delay payment until after they have sold all the units of the purchased product. The retailer’s warehouse is limited, but the surplus can be stored in a rented warehouse at a...

In this paper, we investigate the problem of determining a retailer’s optimal cycle time and the optimal payment policy when supplier offers partially or fully permissible delay in payment linking to payment time. The retailer can obtain the larger fraction of the delay payment permitted by the supplier when the retailer chooses the shorter delayed payment period. The supplier uses this policy ...

In a recent paper, Khanra, Ghosh and Chaudhuri’s (2011) presented an EOQ model for a deteriorating item with time dependent quadratic demand under permissible delay in payment. Deterioration considered in most of the EOQ models is constant, while in most of the practical cases the deterioration rate increases with time. This work is motivated by Khanra, Ghosh and Chaudhuri’s (2011) paper extend...

Kandpal Deepa H. & Tinani Khimya S. Department of Statistics, Faculty of Science, The M.S. University of Baroda Vadodara-390002, Gujarat, India . ABSTRACT This paper develops a model to determine an optimal ordering policy for deteriorating items under permissible delay of payment and allowable shortage for future supply uncertainty for two suppliers. In this paper we have introduced the aspect...

A deterministic inventory model with two levels of storage (own warehouse and rented warehouse) with non-instantaneous deteriorating items is studied. The supplier offers the retailer a trade credit period to settle the amount. Different scenarios based on the deterioration and the trade credit period have been considered. In this article, we have framed two models considering single warehouse ...

The classical economic order quantity model of Wilson’s was developed with the assumption that the buyer must pay off immediately on arrival of the goods in the inventory system. In fact, offering buyers to delays payment for goods received is considered as a sales promotional tool in the business world. With offer of trade credit, vendor increases sales, attracts more buyers and reduces on – h...
