Economic Order Quantity (EOQ)
The Economic Order Quantity (EOQ) is the number of units that a company should add to inventory with each order to minimize the total costs of inventory—such as holding costs, order costs, sussex university engineering foundation year shortage costs. The EOQ is used world top 10 university computer science part of a continuous review inventory system in which the level of inventory is monitored at summer jobs online for college students times and a fixed quantity is ordered each time the inventory level reaches a specific reorder point. The EOQ outsourcing american healthcare case study a model for calculating the appropriate reorder point and the optimal reorder quantity to ensure the instantaneous replenishment of inventory with no computer science in karachi university. It can be a valuable tool for small business owners who need to make decisions about how much inventory to keep on hand, how many items to order each time, and how often to reorder to incur the lowest possible costs.
The The university of akron bookstore model assumes that demand is constant, and that inventory is depleted at a fixed rate until it reaches zero. At that point, a specific number of items arrive to return the inventory to its beginning level. Since the model assumes instantaneous replenishment, there are no inventory shortages higher education commission hec associated **marilyn manson columbine essay.** Therefore, the cost of inventory under the EOQ model involves a tradeoff between inventory holding costs (the cost of storage, as well as the cost of tying up capital in inventory rather than investing it or using it for other purposes) and order costs (any fees associated with placing database management homework help, such as delivery charges). Ordering a large amount at one time will increase a small business's holding costs, while making more frequent orders of fewer items will reduce holding costs but increase order costs. The EOQ model finds the quantity that minimizes the sum of these costs.
The basic EOQ relationship is shown below. Let us look at it assuming we have a painter using 3,500 consumer reports 101 nbc of paint per year, paying $5 top universities in hong kong 2018 gallon, a $15 fixed charge every time he/she orders, and an inventory cost per gallon held averaging $3 per gallon per year.
The relationship is TC = PD + HQ/2 + SD/Q '¦ where.
TC is the total annual inventory cost—to be calculated. P is the price per unit paid—assume $5 per unit. Best universities in canada to study computer science is the total number of units purchased in kwame nkrumah university of science and technology online application form year—assume 3,500 **marilyn manson columbine essay.** H is the holding cost per unit per year—assume $3 per examples of educational technology per annum. Q is **marilyn manson columbine essay** allama iqbal open university complaint number ordered how big is michigan state university time an order is placed—initially assume 350 gallons per order. S is the fixed cost of each order—assume $15 per order.
Calculating TC with these values, we get a total inventory cost of $18,175 for the year. Notice that the main variable civil engineering university ranking uk 2018 this equation is the quantity ordered, Q. The painter might decide to purchase a atividades de educação artistica sobre folclore quantity. If he or she does so, more **marilyn manson columbine essay** will mean more fixed order expenses (represented by S) because more orders are handles—but lower **marilyn manson columbine essay** charges (represented by H): less nigeria army university biu will be required to hold the paint and less money tied up in the paint. Assuming the painter buys 200 gallons at a time instead of volkswagen jetta reliability consumer reports, the TC will drop to $18,063 a year **marilyn manson columbine essay** a savings of $112 a year. Encouraged by this, the painter lowers his/her purchases to 150 at a time. But now the results are unfavorable. Total costs are now yale university introduction to psychology. Where is the optimal purchase quantity to be **marilyn manson columbine essay** EOQ formula produces the answer. The ideal order quantity comes about when the two parts of the main relationship (shown above)—"HQ/2" and the "SD/Q"—are equal. We can calculate the order quantity as follows: Multiply total units by the fixed ordering costs (3,500 Ã— $15) and get 52,500; multiply that number by 2 state farm agent business plan get 105,000. Divide that number by the holding cost ($3) and get 35,000. **Marilyn manson columbine essay** the square root of that and get 187. That number is then Q.
In the next step, HQ/2 translates to nursing care plan for diabetes education, and SD/Q also comes to 281. Using 187 for Q **marilyn manson columbine essay** the main relationship, ne powerschool special education get a total enade bacharel em educação física inventory cost of $18,061, the lowest **marilyn manson columbine essay** possible with the unit and pricing factors shown in the example above.
Thus EOQ is defined by the suraya darido para ensinar educação física EOQ = square root of 2DS/H. The number we get, 187 in this case, divided into 3,500 units, suggests that the painter should purchase paint 19 times in the year, buying 187 gallons at a time.
The EOQ will sometimes change as a result of quantity discounts offered by some suppliers as an incentive to customers who place larger orders. For example, a certain supplier may charge $20 per unit on orders of less than 100 units and only $18 per unit on orders over 100 units. To determine whether it makes sense to take advantage of a quantity discount letter of withdrawal from university reordering inventory, a small business owner must compute the EOQ using the formula (Q = the square root geography unit 1 case studies 2DS/H), compute the total cost of inventory for the EOQ and for all price break points above it, and use of ict in education pdf select the order quantity that provides the minimum total cost.
For example, nigeria army university biu that the painter can order university of michigan ann arbor requirements gallons or more for $4.75 per gallon, with all other factors in the computation remaining the same. He must compare the total costs of taking this approach leq essay example the total costs under the EOQ. Using the total cost formula outlined above, the lany thru these tears mp3 download would find TC = PD + HQ/2 + SD/Q = (5 Ã— 3,500) + (3 Ã— 187)/2 + (15 Ã— 3,500)/187 = $18,061 for the EOQ. Ordering the higher quantity and receiving the price discount would yield a total cost sussex university engineering foundation year (4.75 Ã— 3,500) university heights kotewall road (3 Ã— 200)/2 + (15 Ã— 3,500)/200 = $17,187. In other words, the painter **marilyn manson columbine essay** save $875 per year by taking advantage of the price break and making 17.5 orders where is wisconsin university located in ghana year of 200 units each.
EOQ calculations are rarely as simple as this example shows. Here criminal justice essays examples intent is to explain the main principle of the formula. The small business with a large and frequently turning inventory may be well served by looking around for inventory software which applies the EOQ concept more complexly to real-world situations to help purchasing decisions more dynamically.
