INVENTORY MODEL OF DETERIORATING PRODUCTS WITH LIFE TIME

In this paper, an inventory model of deteriorating products with life time has been discussed. Demand rate has been taken of quadratic form which starts from zero in the beginning and ends to zero at the completion of the cycle. Deterioration rate has been taken constant. Shortages are considered and backlogged. Cost minimization technique has been used in the development of the model. Key-words: Deterioration, life time, shortages and backlogged. Inventory models involving time dependent demand pattern have received the attention of several researchers. Silver and Meal (1973), Donaldson (1977), Ritchie (1984) are worth mentioning for doing work in this direction. Mitra et al. (1984) presented a simple procedure for adjusting the economic order quantity (EOQ) model for the cases of increasing or decreasing linear trend in demand. Dave & Pate
