A TWO WAREHOUSE INVENTORY MODEL FOR DETERIORATING ITEMS WITH GENERALIZED EXPONENTIAL DECREASING STOCK DEPENDENT DEMAND, CONSTANT HOLDING COST AND TIME-VARYING DETERIORATION RATE

In this paper, an inventory model is considered with generalized exponential decreasing stock-dependent demand rate and constant holding cost. Here we had considered two types of warehouses OW (Own Warehouse) and RW (Rented Warehouse) where holding cost for OW is zero and RW is dependent on time of storage and quantity of items stored. The deterioration rate is a time-varying, linear function of time. Shortages are not allowed. A numerical example is used to illustrate the application of the model and some sort of analysis of the optimal solution with respect to various parameters is carried out, to see the effect of parameter changes on the solution.
