After the computing the EOQ, we round up to the nearest whole number if the optimal unit to order is not a whole number. Rounding up, as opposed to rounding to the nearest whole number, as rounding to the nearest whole number may violate the assumption that "no partial deliveries" assumption assumed by the basic EOQ formulation. may violate the assumption that "there should never be any stockouts" assumed by the EOQ model. may violate the assumption that "the cost to purchase or produce is the same" assumed by the EOQ model. may violate the assumption that "demand is known with certainty" assumed by the EOQ model
