Solution:

QUESTION: 9

The demand for a commodity is 100 units per day. The ordering cost is Rs. 200/order and the carrying cost is Rs. 20/unit/year. If the lead time is 13 days, the re-order point is ____________

Solution:

Daily demand = 100 units

LT = 13 days

ROP/ROL = daily demand × LT

= 100 × 13 = 1300 units

*Answer can only contain numeric values

QUESTION: 10

The annual demand for a product is 60,000 units, the ordering cost is Rs. 8000 per order. Considering Wilsons model, the EOQ is 12,000

units. When the annual inventory cost is minimized, the annual inventory holding cost is Rs ___________

Solution:

D = 60,000

C_{o} = Rs. 8000/order

EOQ = 12,000

Annual inventory holding cost

= Rs. 40,000

QUESTION: 11

A company has an annual demand of 3000 units, the ordering cost per order is Rs. 50 and the carrying cost is Rs. 5 per unit-year. The backorder costs are estimated as Rs. 20 per unit-year. The maximum inventory is (approximately)

Solution:

D = 3000 units

C_{o} = Rs. 50/order

C_{c} = Rs. 5/unit/year

C_{s} = Rs. 20/unit/year

Q_{s} =?

≃ 274

Q_{max} = 219.2 ≈ 220

*Answer can only contain numeric values

QUESTION: 12

Solution:

= Rs. 4412

*Answer can only contain numeric values

QUESTION: 13

A manufacturing company has a contract to supply 5000 components to an automobile company per day. The manufacturing capacity of the company is 7000 components per day. The carrying cost of 1000 components is 20 paise per day. The set-up cost is Rs. 20. The total inventory cost per annum on optimum basis is __________

Solution:

Consumption rate = d = 5000/day

Production rate = k = 7000/day

= 0.073

TC)min = 1233.9

*Answer can only contain numeric values

QUESTION: 14

The annual demand for an item is 5200 units. The ordering cost is Rs. 200/order. The inventory holding cost on average inventory is 20%. The unit cost is Rs. 5 and the storage cost based on maximum inventory is 10 paise per unit per year. EOQ will be __________ units.

Solution:

Total CC = Holding cost + Storage cost

= 0.2 × 5 + 0.1

*Answer can only contain numeric values

QUESTION: 15

A company follows an EOQ system with the following data

Annual demand = 15,000 units

unit cost = Rs. 50

ordering cost = Rs. 240/order

carrying cost = 12% × unit cost

lead time = 15 days

safety stock = 150 units

The re-order level is __________ days.

(A)760

(B)770

Solution:

ROL = safety stock + Demand during lead time

QUESTION: 16

In an ideal inventory control system, the economic lot size for a part is 200 units. If the annual demand for the part is increased by 4 times and carrying cost is decreased by ½, the new EOQ is __________

Solution:

EOQ 1 = 200

*Answer can only contain numeric values

QUESTION: 17

The demand during lead time is 250 units. The annual consumption is 4000 units. The company has a policy of EOQ ordering and maintains a buffer stock of 200 units. The reorder level is _____________ units.

(A)450

(B)450

Solution:

ROL = safety stock + lead time demand

= 200 + 250

= 450

QUESTION: 18

Consider the following data:

Annual demand = 3000 units

Ordering cost = Rs. 100/order

Carrying cost = 25% of unit price

Optimal order quantity is

Solution:

EOQ = 516.39

(Satisfying the Range) Optimal order quantity = 516

*Answer can only contain numeric values

QUESTION: 19

A washer manufacturing company has a contract to supply 5000 washers to an automobile industry per day. The company has a capacity to manufacture 10,000 washers/day and holding cost of one washer is Rs. 0.2 per year. Set up cost is Rs. 20. The length of the production cycle is approximately (in days) __________.

Solution:

Consumption rate = d = 5000/day

production rate = k = 10000/day

C_{c} = Rs. 0.2/unit/year

C_{o} = Rs. 20/order

Length of production cycle = cycle time

= 27018.5

= 5.4 days
