This study also considers the existence of product deficiencies and partial backlogging during the market demand process. Market demand is assumed to be a function of the ramp where the demand for products initially increases a few moments then stabilizes and at the end is constant. This research is completed using the EOQ method. By minimizing the cost of inventory per cycle, the optimum amount and times are obtained to place an order for each cycle. This is a review of the Aggrwal and Singh article [Trends in Applied Sciences Research, 14 (2019), 7-11].enInventory modelEOQpartial backloggingArticle
