EOQ, Economic Order Quantity

An Economic found mensuration is the optimal number of company that minimizes total variable be required to order and hold job-taking, that is to say, that EOQ helps us to settle down the appropriate amount and frequency when ordering and holding inventory. EOQ is use as part of a continuous review inventory system, in which the level of inventory is monitored at all measures, and a fixed quantity is ordered each time the inventory level reaches a particular(prenominal) reorder point, as it shown in the left-hand graphic, where R is the minimum inventory.Moreover, EOQ is essentially an accounting formula that determines the point at which the combination of order costs and inventory carrying costs are the least. The result is the most cost telling quantity to order. Also, EOQ is generally recommended in operations where strike is relatively steady, items with demand variability such as seasonality usher out save use the stupefy by going to shorter time closes for th e EOQ calculation. This Model have som assumptions that are grave to take into account 1. necessity is known and is deterministic, ie. constant. 2. The lead time, ie. he time between the placement of the order and the notice of the order is known and constant. 3. The receipt of inventory is instantaneous. In other words the inventory from an order arrives in one batch at one point in time. 4. Quantity discounts are not possible, in other words it does not mention any difference how much we order, the price of the product will still be the same. (for the Basic EOQ-Model) 5. That the only costs pertinent to the inventory imitate are the cost of placing an order and the cost of holding or storing inventory over time.The basic Economic Order Quantity (EOQ) formula is WhereA = Demand for the year Cp = appeal to place a single order Ch = Cost to hold one unit inventory for a year Then, the earlier formula try to Minimize the Total cost per period, that consist in Total cost per per iod = inventory holding costs per period + order costs per period Where Order Cost = The Number of Orders pose in the period x Order Costs Carrying Cost = average Inventory Level x the Carrying Costs of 1 unit of profligate for one period Then as a Result of this minimizing we lower the Total Relevant Cost (TRC) which is TRC = yearbook Holding Cost + Yearly Ordering Cost = So we can see that the Economic Order Quantity (EOQ) is derived from this formula as the graphic shows. Economic Order Quantities can also have many variations on its basic model. The most utilizable ones are * Quantity discount logic can be programmed to build in conjunction with the EOQ formula to determine optimum order quantities. approximately systems will require this additional programming. * Additional logic can be programmed to determine max quantities for items subject to spoilage or to prevent obsolescence on items reaching the end of their product life cycle. When used in manufacturing to determi ne lot sizes where production bombardments are very long (weeks or months) and ruined product is being released to stock and consumed/sold throughout the production run you may need to take into account the ratio of production to inhalation to more accurately represent the average inventory level. * Your safety stock calculation may take into account the order cycle time that is driven by the EOQ. If so, you may need to tie the cost of the careen in safety stock levels into the formula.
