In this paper we study a periodic review inventory model with stock dependent demand. When stock on hand is zero, the inventory manager offers a price discount to customers who are willing to backorder their demand. Permissible delay in payments allowed to the inventory manager is also taken into account. Numerical examples are cited to illustrate the model.

An inventory model for Weibull deteriorating items with time varying demand under permissible delay in payments and inflation is considered. Holding cost is linear function of time. Shortages are permitted and are completely backlogged. Sensitivity with respect to parameters has been carried out. Numerical example is taken to support the model.

Background and Objectives: In the real world, the obsolescence items are some items that lose their value over time due to the emergence of new technology. Because of rapid changes in technology, inventory management of such items is considered in recent years. Moreover, suppliers try to encourage the retailers for purchasing an item before it is outmoded with some policies suc...

The present Paper deals with an inventory production policy for a ramp type deteriorating item over finite planning horizon constant demand, rate and shortages are not allowed. optimal number of cycles that minimizes the average system cost is determined. model permits shortage in each cycle, which completely backlogged within cycle itself. Every starts zero stock production. As continues, begi...

This paper develops an economic lot-sizing production model for deteriorating items with time dependent quadratic demand and delay in payments under two levels of trade credit policy. The trade credit policy adopted here is a two-level trade credit policy in which the supplier offers the retailer a permissible delay period M, and the retailer in turn provides customers a permissible delay perio...
