Economic Order Quantity (EOQ) Question 1:

Find the economic order quantity for annual demand of an item to be 6000 units, item cost per unit as Rs. 500, ordering cost per purchase order is Rs. 1000 and cost of holding the inventory per unit per year is Rs. 48.

  1. 500
  2. 250
  3. 1000
  4. 750

Answer (Detailed Solution Below)

Option 1 : 500

Economic Order Quantity (EOQ) Question 1 Detailed Solution

Concept:

The ordering quantity Q* at which holding cost becomes equal to ordering cost and the total inventory cost is minimum is known as Economic order Quantity (EOQ).

At EOQ:

Ordering cost = Holding cost

\(\frac{D}{{{Q^*}}}{C_o} = \frac{{{Q^*}}}{2}{C_h} \Rightarrow {Q^*} = \sqrt {\frac{{2D{C_o}}}{{{C_h}}}} \)

D = Annual or yearly demand of inventory (unit/year)

Q = Quantity to be ordered at each order point (unit/order)

Co = Cost of placing one order [Rs/order]

Ch = Cost of holding one unit in inventory for one complete year [Rs/unit/year]

Calculation:

D = 6000 units, Co = Rs. 1000, Ch = 48

\({{\rm{Q}}^{\rm{*}}} = \sqrt {\frac{{2{\rm{D}}{{\rm{C}}_{\rm{o}}}}}{{{{\rm{C}}_{\rm{h}}}}}} = \sqrt {\frac{{2 \times 6000 \times 1000}}{{48}}} = 500{\rm{\;units}}\)

Economic Order Quantity (EOQ) Question 2:

For a single item inventory system, the demand is continuous, which is 10000 per year. The replenishment is instantaneous and backorders (S units) per cycle are allowed as shown in the figure.

F2 S.C Madhu 14.03.20 D 24

As soon as the quantity (Q units) ordered from the supplier is received, the backordered quantity is issued to the customers. The ordering cost is Rs. 300 per order. The carrying cost is Rs. 4 per unit per year. The cost of backordering is Rs. 25 per unit per year. Based on the total cost minimization criteria, the maximum inventory reached in the system is ______ (round off to nearest integer).

Answer (Detailed Solution Below) 1130 - 1140

Economic Order Quantity (EOQ) Question 2 Detailed Solution

Concept:

In a back order model every time after stock out period when quantity Q is received the inventory level reaches its maximum level.

Economic order quantity \( = \sqrt {\frac{{2D{C_o}}}{{{C_h}}}\left( {\frac{{{C_b} + {C_h}}}{{{C_b}}}} \right)}\) 

Maximum inventory \(= \sqrt {\frac{{2D{C_o}}}{{{C_h}}} \times \left( {\frac{{{C_b}}}{{{C_b} + {C_h}}}} \right)}\) 

Where, D is the demand per year, Cb is the backordering cost per unit per year and Ch is the carrying cost per unit per year

Cis the ordering cost per order

Calculation:

Given, D = 10000/year, Ch = 4 /unit/year, Co = 300/order, Cb = 25 /unit/year

\({Q_{max}} = \sqrt {\frac{{2 \times 10,000 \times 300}}{4} \times \frac{{25}}{{25 + 4}}}\)

Qmax = 1137.147 units

Economic Order Quantity (EOQ) Question 3:

With reference to the Economic Order Quantity (EOQ) model, which one of the options given is correct? 

F2 Madhuri Engineering 08.03.2023 D4

  1. Curve P1: Total cost, Curve P2: Holding cost, Curve P3: Setup cost, and Curve P4: Production cost.
  2. Curve P1: Holding cost, Curve P2: Setup cost, Curve P3: Production cost, and Curve P4: Total cost. 
  3. Curve P1: Production cost, Curve P2: Holding cost, Curve P3: Total cost, and Curve P4: Setup cost. 
  4. Curve P1: Total cost, Curve P2: Production cost, Curve P3: Holding cost, and Curve P4: Setup cost.

Answer (Detailed Solution Below)

Option 1 : Curve P1: Total cost, Curve P2: Holding cost, Curve P3: Setup cost, and Curve P4: Production cost.

Economic Order Quantity (EOQ) Question 3 Detailed Solution

Explanation:

Curve P2: Holding cost

F2 Madhuri Engineering 08.03.2023 D5

Holding cost = \(\rm \frac{Order\ quantity}{2}× \frac{Carrying\ cost}{\frac{unit}{unit\ time}}\)

\(\rm =\frac{Q}{2}× C_c\)

⇒ Holding cos t ∝ Q

Curve P3: Setup cost

F2 Madhuri Engineering 08.03.2023 D6

Setup cost (or) ordering cost

= No. of setups × setup cost / setup

\(\rm=\frac{Annual\ demand}{Order\ quantity}× \frac{setup\ cos\ t}{setup}\)

\(\rm =\frac{D}{Q}× C_0\)

⇒ Ordering (or setup cost ∝ \(\rm \frac{1}{Q}\)

Curve P4: Production (or) Material cost

F2 Madhuri Engineering 08.03.2023 D7

Curve P1: Total cost

F2 Madhuri Engineering 08.03.2023 D8

Annual production cost = Annual demand × unit cost

= D × Cu

⇒ Production cost is independent of order quantity.

TC = holding cost + setup cost + production cost

Economic Order Quantity (EOQ) Question 4:

Identify the equation that is used to find the quantity giving the most economic order.

where 'A' is the total item consumed per year

'P' is the purchase cost per order

'C' is the annual inventory carrying cost per item.

  1. \(\sqrt{\frac{AP}{2C}}\)
  2. \(\sqrt{\frac{AP}{C}}\)
  3. \(\sqrt{\frac{2AC}{P}}\)
  4. \(\sqrt{\frac{2AP}{C}}\)

Answer (Detailed Solution Below)

Option 4 : \(\sqrt{\frac{2AP}{C}}\)

Economic Order Quantity (EOQ) Question 4 Detailed Solution

Explanation:

Economic order quantity (EOQ):

  • Economic order quantity is the size of the order which helps in minimizing the total annual cost of inventory in the organization.
  • When the size of the order increases, the ordering costs (cost of purchasing, inspection, etc.) will decrease whereas the inventory carrying costs (costs of storage, insurance, etc.) will increase.
  • Economic Order Quantity (EOQ) is the size of an order which minimizes total annual costs of carrying and cost of ordering.

RRB JE ME 39 15Q IM Part 2 Hindi - Final Diagram Madhu images Q6

  • It is evident from above that the minimum total costs occur at a point where the ordering costs and inventory carrying costs are equal.

At EOQ:

Ordering cost = Holding cost

\(\frac{D}{{{Q^*}}}{C_o} = \frac{{{Q^*}}}{2}{C_h} \Rightarrow {Q^*} = \sqrt {\frac{{2A{P}}}{{{C}}}} =\sqrt {\frac{2(Annual\:Usage\:in\:units)\times (Order\:cost)}{(Annual\:carrying\:cost\:per\:unit)}}\)

A = Annual or yearly demand for inventory (unit/year)

Q = Quantity to be ordered at each order point (unit/order)

P = Cost of placing one order [Rs/order]

C = Cost of holding one unit in inventory for one complete year [Rs/unit/year]

Economic Order Quantity (EOQ) Question 5:

A plastic moulding firm produces and uses 24000 bearings. The setup cost is Rs.20 and production rate per week is 1000 units. If inventory carrying cost is Rs.1.50 per unit per year, the maximum inventory level is (nearest integer) ____ units.

(1 year = 50 working weeks)

Answer (Detailed Solution Below) 575 - 580

Economic Order Quantity (EOQ) Question 5 Detailed Solution

Concept:

For production model

\(EOQ = \sqrt {\frac{{2D{C_0}}}{{{C_h}}}\left\{ {\frac{p}{{p - d}}} \right\}} \)

Where,

p = production per week, d = demand per week

\(d = \frac{{24000}}{{50}} = 480/week\)

p = 1000/week

\(\therefore EOQ = \sqrt {\frac{{2 \times 24000 \times 20}}{{1.5}}\left\{ {\frac{{1000}}{{1000 - 480}}} \right\}} \)

∴ EOQ = 1109.4 units

\(\therefore {Q_{max}} = \frac{{\left( {p - d} \right)}}{p}EOQ\)

∴ Qmax = 576.88 = 577

Economic Order Quantity (EOQ) Question 6:

The demand for a certain item is 200 units per period. Unsatisfied demand causes a shortage cost of Rs. 0.75 per unit per short period. The cost of initiating purchasing action is Rs. 10.00 per purchase and the holding cost is 15% of average inventory valuation per period. Item cost is Rs. 8.00 per unit. (Assume that shortages are being back ordered at the above-mentioned cost). The minimum inventory cost is

Answer (Detailed Solution Below) 40 - 45

Economic Order Quantity (EOQ) Question 6 Detailed Solution

Concept:

Total inventory cost is given by,

\(\left( {TIC} \right) = \sqrt {2D{C_o}{C_h}} .\sqrt {\frac{{{C_b}}}{{{C_b} + {C_h}}}} \)

where, D = annual demand, C0 = ordering cost, Ch = holding cost, Cb = Shortage cost 

Calculation:

Given:

Demand (D) = 200

Shortage cost (Cb) = 0.75 Rs. Per unit

Ordering cost (Co) = 10 Rs. Per order

Item cost (C) = 8 per unit

Holding cost (Ch) = 15% = 0.15 × 8 = 1.20 Rs.

Now, Total inventory cost 

\(\left( {TIC} \right) = \sqrt {2D{C_o}{C_h}} .\sqrt {\frac{{{C_b}}}{{{C_b} + {C_h}}}} \)

\( = \sqrt {2 \times 200 \times 10 \times 1.2} \sqrt {\frac{{0.75}}{{0.75 + 1.2}}} \)

= Rs. 42.96.

Thus, The minimum inventory cost is Rs. 42.96

Economic Order Quantity (EOQ) Question 7:

A contractor has to supply 10,000 bearings per day to an automobile manufacture. The bearings production per day is 25000. The cost of holding a bearings in stock one year is Rs. 2 and the set-up cost of a production run is 1800. Find the frequency of production run in days. (Take 300 working days in a year).

Answer (Detailed Solution Below) 9.46 - 9.49

Economic Order Quantity (EOQ) Question 7 Detailed Solution

Annual demand = 10000 × 300 = 3000000

Holding cost Ch = 2

Set-up cost (Co) = 1800

Production rate (p) = 25000 bearings per day

Consumption rate (d) = 10,000 bearings per day

Economic order quantity \({Q^*} = \sqrt {\frac{{2D{C_o}}}{{{C_h}}}\left( {\frac{P}{{P - d}}} \right)} \)

\( = \sqrt {\frac{{2 \times 3000000 \times 1800}}{2}\left( {\frac{{25000}}{{25000 - 10,000}}} \right)} \)

Q* = 94868 bearings

∴ Length of production cycle \( = \frac{{94868}}{{10000}} = 9.486\;days\)

Economic Order Quantity (EOQ) Question 8:

 A manufacturing company XYZ purchases 50,000 parts of a machine for its annual requirements and each part cost is Rs. 40. The ordering cost per order is Rs. 25 and the inventory holding charges are 10% of the unit cost per year. If the maximum quantity that can be ordered at a time is 600 units. What will be the minimum total inventory cost?

Answer (Detailed Solution Below) 3283 - 3284

Economic Order Quantity (EOQ) Question 8 Detailed Solution

Calculation:

Given:
D = 50,000 units per year  CO = Rs.25 per order, Cu = Rs. 40 per unit

Cc = 0.1 of Cu = 0.1 × 40 = 4 Rs per unit per year

\(EOQ = \sqrt {\frac{{2D{C_O}}}{{{C_c}}}} \)  

\(EOQ = \sqrt {\frac{{2 \times 50,000 \times 25}}{4}} \)
⇒ [EOQ = 790.569 units]

∵ EOQ > Maximum quantity that can be ordered at one

So, (TIC)= 600 \(= \frac{D}{Q} \times {C_O}\, + \,\frac{Q}{2} \times {C_N}\)

\((TIC)_{Q = 600 } = \frac{{50,000}}{{600}} \times 25 + \frac{{600}}{2} \times 4\)

⇒ (TIC)Q = 600 = Rs. 3283.33

Economic Order Quantity (EOQ) Question 9:

In inventory control, the economic order quantity is the

  1. Optimum lot size
  2. Highest level of inventory
  3. Capability of plant to produce
  4. None of these

Answer (Detailed Solution Below)

Option 1 : Optimum lot size

Economic Order Quantity (EOQ) Question 9 Detailed Solution

Explanation:

Economic Order Quantity (EOQ): 

  • A decision about how much to order has great significance in inventory management.
  • The quantity to be purchased should neither be small nor big because the costs of buying and carrying materials are very high.
  • Economic order quantity is the size of the lot to be purchased which is economically viable.
  • This is the number of materials that can be purchased at minimum costs.
  • Generally, economic order quantity is the point at which inventory carrying costs are equal to order costs.

Economic Order Quantity (EOQ) Question 10:

Which of the following statements concerning the basic EOQ model is true?

  1. A decrease in demand will increase the EOQ value
  2. If an actual order quantity is smaller than-the EOQ, the annual holding cost is less than the annual ordering cost.
  3. An increase in holding cost will increase the EOQ value.
  4. In the EOQ formula there is an inverse relationship between setup and carrying costs.

Answer (Detailed Solution Below)

Option 2 : If an actual order quantity is smaller than-the EOQ, the annual holding cost is less than the annual ordering cost.

Economic Order Quantity (EOQ) Question 10 Detailed Solution

Concept:

Economic order quantity

Economic order quantity is that size of the order which helps in minimizing the total annual cost of inventory in the organization.

When the size of the order increases, the ordering costs (cost of purchasing, inspection, etc.) will decrease whereas the inventory carrying costs (costs of storage, insurance, etc.) will increase. Economic Order Quantity (EOQ) is that size of order which minimizes total annual costs of carrying and cost of ordering.

The ordering quantity Q* at which holding cost becomes equal to ordering cost and the total inventory cost is minimum is known as Economic order Quantity (EOQ).

RRB JE ME 39 15Q IM Part 2 Hindi - Final Diagram Madhu images Q6

At EOQ:

Ordering cost = Holding cost

\(\frac{D}{{{Q^*}}}{C_o} = \frac{{{Q^*}}}{2}{C_h} \Rightarrow {Q^*} = \sqrt {\frac{{2D{C_o}}}{{{C_h}}}} \)

D = Annual or yearly demand of inventory (unit/year)

Q = Quantity to be ordered at each order point (unit/order)

Co = Cost of placing one order [Rs/order]

Ch = Cost of holding one unit in inventory for one complete year [Rs/unit/year]

if the total ordering quantity is less than the EOQ quantity, then the holding cost is less than the ordering quantity.
