The simple, or basic, economic order quantity (EOQ) is a special case of the continuous rate EOQ, which can be derived from the equation of total cost as follows.
Here is the equation for total cost (TC) as a function of run size (q):
TC(q) = K*D/q + P*D + q*H(r - D)/(2r), where:
K = Fixed cost per order
D = Annual Demand of product
q = run size
P = Purchasing cost per unit
H = Annual holding cost per unit
r = Production rate
K*D/q = Setup cost
P*D = Purchasing cost
H(r - D)/(2r) = holding cost.
To find the maximum value of q, you take the derivative, d[TC(q)]/dq, set it equal to zero, and solve for q.
First, take the derivative:
d[TC(q)]/dq = -K*D/q2 + H(r - D)/(2r).
Then, to maximize, set this equal to zero, and solve for q:
H(r - D)/(2r) - K*D/q2 = 0,
q2 = (2*r*K*D)/[H(r - D)],
q = √((2*r*K*D)/[H(r - D)]).
That's the formula for the continuous rate EOQ.
Basic EOQ is the special case of r >> D, which means r - D pretty much equals r, which allows you to cancel the r's in the above equation, giving you the formula:
q = √((2*K*D)/H).
This is the formula for basic EOQ.

What is production order quantity model?
Production Order Quantity (POQ) is a model that answers how much to produce and when to order. In this model, the materials produced are used immediately and hence lowering the holding cost that in Economic Order Quantity (EOQ).
How do you calculate the holding cost in the Economic Order Quantity (EOQ) model?
The holding cost in the Economic Order Quantity (EOQ) model is calculated by multiplying the holding cost per unit by the average inventory level. The holding cost per unit is the cost to store one unit of inventory for a certain period of time, and the average inventory level is half of the order quantity.
Criticism to Economic order quantity?
The assumptions included in the EOQ models are simplistic;The real cost of stock in operations are not as assumed in EOQ models;The models are really descriptive and should not be used as prescriptive devices.
How do you use EOQ to determine when to order items how many and how to order a specific number?
The Economic Order Quantity (EOQ) model helps determine the optimal order quantity that minimizes total inventory costs, including holding and ordering costs. To use EOQ, you first calculate the EOQ using the formula: (EOQ = \sqrt{\frac{2DS}{H}}), where (D) is the annual demand, (S) is the ordering cost per order, and (H) is the holding cost per unit per year. Once you have the EOQ, you can establish reorder points based on lead time and usage rates to determine when to place orders. To order a specific number, simply place an order for the EOQ amount whenever the inventory reaches the reorder point.
What are the primary variables being balanced in the EOQ inventory model?
The primary variables being balanced in the EOQ model are carrying costs and ordering costs. The more frequent orders are placed the lower the firm's carrying costs and the higher its ordering costs.

What is Economic Order Quantity (EOQ) and how is EOQ calculation helpful for businesses?
Economic Order Quantity (EOQ) is a formula used by businesses to determine the optimal order quantity that minimizes total inventory costs, which include ordering costs and holding costs. By calculating EOQ, businesses can ensure they don’t overstock or understock their inventory, leading to cost savings. The EOQ calculation helps determine the ideal order quantity, taking into account factors such as demand, ordering cost, and holding cost. To calculate EOQ, the formula is: EOQ = √(2DS/H) Where: D = Demand rate (units per year) S = Ordering cost per order H = Holding cost per unit per year By using this formula, businesses can efficiently manage their inventory, reduce unnecessary expenses, and maintain optimal stock levels, improving overall supply chain management. Cloud-based ERP systems can automate EOQ calculations to streamline operations.
What is the fomula used to calculate the optimal order quality?
The formula to calculate the optimal order quantity is known as the Economic Order Quantity (EOQ) model, which is given by the formula: [ EOQ = \sqrt{\frac{2DS}{H}} ] where ( D ) is the annual demand for the product, ( S ) is the ordering cost per order, and ( H ) is the holding cost per unit per year. This formula helps businesses minimize total inventory costs by determining the most cost-effective quantity to order.
How do you find total holding cost using EOQ method?
To find the total holding cost using the Economic Order Quantity (EOQ) method, first, calculate the EOQ using the formula ( EOQ = \sqrt{\frac{2DS}{H}} ), where ( D ) is the annual demand, ( S ) is the ordering cost per order, and ( H ) is the holding cost per unit per year. Once you have the EOQ, determine the average inventory level, which is ( \frac{EOQ}{2} ). Multiply this average inventory by the holding cost per unit to get the total holding cost: ( \text{Total Holding Cost} = \frac{EOQ}{2} \times H ).

Can eoq answer be in points?
Yes, the Economic Order Quantity (EOQ) can be presented in points for clarity. Key points to consider include: EOQ minimizes total inventory costs by balancing ordering and holding costs. It determines the optimal order quantity that minimizes waste and maximizes efficiency. The formula for EOQ is ( \sqrt{\frac{2DS}{H}} ), where ( D ) is demand, ( S ) is ordering cost, and ( H ) is holding cost. This concise format helps in quick understanding and application of the EOQ concept.
How would you respond to the criticism that eoq model tend to provide misleading results because value of d s and h are at best educated guesses?
While it's true that the EOQ model relies on input parameters that are estimates, it still provides a useful starting point for inventory management. By continually updating and refining these inputs based on real-world data and experience, the EOQ model can become more accurate over time. Additionally, sensitivity analysis can help in understanding the impact of variations in these parameters on the model's output.
