EOQ model for items with Weibull distribution deterioration, shortages and trended demand

The present paper deals with an inventory model for deteriorating items with instantaneous supply, linearly increasing demand and shortages in inventory. A two-parameter Weibull distribution is taken to represent the time to deterioration. A theory is developed to obtain the optimal solution of the problem; it is then illustrated with the help of a numerical example. The sensitivity of the optimal solution towards changes in the values of different system parameters is also studied.
