• AN INVENTORY MODEL WITH WEIBULL DISTRIBUTION DETERIORATION UNDER QUADRADIC DEMAND RATE USING PARTIAL BACKLOGGING

Abstract

Many Researchers have developed an inventory model to maximize the profit or to minimize the total cost for deteriorating items with respect to time. Deterioration in each product cannot be completely avoided and the rate of deterioration for each product will vary. We have studied an inventory model for two parameter Weibull distribution deterioration with quadratic demand rate, in which shortages are allowed and are partially backlogged and assumed that the backlogging rate is dependent on the length of the waiting time for the next replenishment.  The results were described using numerical examples and sensitivity analysis.
