Economic production quantity (EPQ) models are developed to determine the optimal production quantity, which include the different uncertainty of the manufacturing systems even though they were to be deterministic, such as variations of demand and related cost values etc. Also we know that the basic assumption of EPQ model is that 100% of manufactured products are non-defective and there are no shortages.
