OPTIMAL INVENTORY MODEL FOR DETERIORATING PRODUCTS WITH WEIBULL DISTRIBUTION DETERIORATION, STOCK AND TIME-DEPENDENT DEMAND, TIME-VARYING HOLDING COST UNDER FULLY BACKLOGGING

摘要

Effect of deterioration plays a vital role in present environment of market. In this paper, an optimal inventory model for deteriorating items having stock and time dependent demand under the effects of deterioration is studied. A two parameter Weibull distribution is used to represent the distribution of the time to deterioration. In which the shortages are allowed and fully backlogged. The model is solved analytically by minimizing the total inventory cost. Some numerical examples have been carried out to illustrate the developed model.
