خلاصة:
This paper presents an inventory model for deteriorating items in which shortages are
allowed. It is assumed that the production rate is proportional to the demand rate. The
production rate is considered to be greater than demand rate. The inventory model is
developed by considering four different circumstances. The optimal of the problem is
obtained with the help of Mathematica 7 software. Numerical example is given to illustrate
the model. Sensitivity analysis of the model has been developed to examine the effect of
changes in the values of the different parameters for optimal inventory policy.

Ray and Chaudhuri (1997) developed a finite time- horizon deterministic economic order quantity inventory model with shortages where the demand rate at any instant depends on the stock- level at that instant.
In the past few decades many researchers have developed inventory models by considering time- dependent demand rate.
Dutta and pal (1991) investigated a finite time- horizon inventory model following the approach to Misra (1979) with linearly time – dependent demand rate allowing shortages and considering the effect of inflation and time value of money.
Soni (2013) developed an EOQ model considering (i) the demand rate as multivariate function of price and level of inventory (ii) delay in payment is permissible.
Tripathi and Pandey (2013) established an inventory model for deteriorating items with Weibull distribution time dependent demand rate under permissible delay in payments.
Tripathi (2011) formulated an inventory model for non- deteriorating item and time dependent demand rate under inflation when supplier offers a permissible delay to the purchaser, if the order quantity is greater than or equal to a predetermined quantity.
