An EOQ (Economic Order Quantity) model for a deteriorating item with quadratic demand pattern and quadratic holding cost and constant deterioration rate is considered in this paper. In addition, shortages and partial backlogging are allowed. It is assumed that the backlogging rate acts as not only a variable, but also depends on the length of the waiting time up to next replenishment during the...

In this paper we develop and analyse an inventory model for deteriorating items with mixture of Weibull rate of decay and demand as function of both selling price and time without shortages. Using the differential equations, the instantaneous state of inventory at time„t‟, the amount of deterioration etc. are derived. With suitable cost considerations the total cost function and profit rate fun...

in paper (2004) chang studied an inventory model under a situation in which the supplier provides the purchaser with a permissible delay of payments if the purchaser orders a large quantity. tripathi (2011) also studied an inventory model with time dependent demand rate under which the supplier provides the purchaser with a permissible delay in payments. this paper is motivated by chang (2004) ...

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...

Business organizations that deal with consumable and perishable items have consistently incurred enormous loss as a result of the nature their goods. The losses direct negative impact on revenues. Unplanned lack precise production prediction models are responsible for this. An appropriate model, developed to guide plan processes will help manufacturers in deciding which product make what quanti...

An EOQ model of inventory for items with linear rate of deterioration is considered, taking the demand rate to be dependent on the stocjk level at any instant of time. The Payments are permitted to be delayed up to certain period of time. Shortages are not allowed. After the certain period, a special discount is permitted to reduce the stock in inventory because if the stock is holded, an inter...
