This work extends inventory models for growing items by considering quality inspections, permissible shortages with complete back-ordering, and holding cost during both the growth and consumption periods. By back-ordering shortages, the firm can avoid sales loss by paying delay penalties to customers who wait for late items. After items reach a certain weight preferred by the customers, they are fully inspected, and inferior-quality items are removed at the end of the inspection period. The model determines the optimum cycle length and shortage level to minimize the total cost of the inventory system. This cost includes purchasing, setup, inspection, feeding, holding, and shortage costs. A nonlinear programming model is formulated, and an optimum solution algorithm is presented
