Jamal et al. [2000. Optimal payment time for a retailer under permitted delay of payment by the wholesaler. International Journal of Production Economics 66, 59–66] study a wholesaler–retailer supply chain where the retailer is given a permissible credit period to pay back the dues without paying any interest to the wholesaler. The problem is modeled as a cost minimization problem with two deci...

Some products like green vegetables, volatile liquids and others deteriorate continuously due to evaporation, spoilage etc. In this study, an inventory model is developed for deteriorating items with linearly time dependent demand rate under inflation and time discounting over a finite planning horizon. Shortages are allowed and linearly time dependent. Mathematical model is presented for the p...

in this paper, we develop an inventory model with delay in payments for deteriorating items. in our model, retailer who purchases the items enjoys a fixed credit period offered by his/her supplier and, in turn, also offers a credit period to his/her customers in order to promote the market competition. the demand is assumed to be linear function of the retailer's current-stock level. the effect...

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...

In this study, an EOQ (Economic Order Quantity) inventory mathematical model is constructed for a deteriorating item having time dependent demand when delay in payment is permissible. The deterioration rate is assumed to be a constant and the time varying demand rate is taken to be an exponential declining function of time. Mathematical models are also derived under two different circumstances,...

In this paper, we derive a partial backlogging inventory model for noninstantaneous deteriorating items with stock-dependent demand rate under inflation over a finite planning horizon. We propose a mathematical model and theorem to find minimum total relevant cost and optimal order quantity. Numerical examples are used to illustrate the developed model and the solution process. Finally, a sensi...
