The economic production quantity model (also known as the EPQ model) determines the quantity a company or retailer should order to minimize the total inventory costs by balancing the inventory holding cost and average fixed ordering cost. Similar to the EOQ model, EPQ is a single product lot scheduling method.
How EOQ and EPQ are related?
In production-inventory control, economic order quantity (EOQ) and economic production quantity (EPQ) models are used to determine the optimal order quantities for purchasing and manufacturing. Most EOQ and EPQ models are constructed assuming constant costs.
What is lot for lot method?
Lot-for-lot is a lot sizing technique, where orders produced are the exact amount needed. In a materials requirement planning (MRP) environment, lot or run size is equal to the net requirements for that period, or demand for that period.
Why does ordering cost decrease with lot size?
11.5 Economic Order Quantity (EOQ) Model The concept is as lot size (q) increases the carrying charges (C1) will increase while the ordering cost (C3) will decrease. On the other hand as the lot size (q) decreases, the carrying cost (C1) will decrease but the ordering costs will increase.
