Expert Solution

Answer to Problem 22P

The optimal order quantity is 200 units with the minimum annual cost of $1,446,380

Explanation of Solution

Given information:

Monthly demand (d)= 400 / month

Holding cost (H) = $35 / unit / year

Ordering cost (S) = $120 / order

Purchase price (P) = $350 / chip

Annual demand (D)=Monthly demand×12 months=400×12=4,800

Price structure:

Quantity purchased	Price / unit
1 – 99 units	$350
100 – 199 units	$325
200 or more units	$300

Formula to calculate EOQ:

EOQ=2×D×SH

Formula to calculate annual holding cost:

Annual holding cost=EOQ2×H

Formula to calculate annual ordering cost:

Annual ordering cost=DEOQ×S

Formula to calculate purchase cost:

Purchase cost=D×P

Formula to calculate total cost:

Total cost=Purchase cost+Annual ordering cost+Annual holding cost

Calculation of EOQ:

EOQ=2×4,800×12035=1,152,00035=32,914.285=181 units

The obtained EOQ value is in the range of (100 – 199 units). Hence, the price of that range will be used for calculation.

Calculation of values at (EOQ = 181):

Calculation of annual holding cost at (EOQ = 181):

Annual holding cost=1812×35=90.5×35=3167.5=$3,168

Calculation of annual ordering cost at (EOQ = 181):

Annual ordering cost=4,800181×120=26.52×120=$3,182

Calculation of purchase cost:

Purchase cost=4,800×325=$1,560,000

Calculation of total cost at (EOQ = 181):

Total cost=1,560,000+3,168+3,182=$1,566,350

The total cost at the (EOQ = 181) is $1,566,350.

Calculation of values at discount quantity (200):

The next price break after the EOQ at 181 units is (200 or more units). The price of that range will be used in the following calculation.

Calculation of annual holding cost at (EOQ = 200):

Annual holding cost=2002×35=100×35=$3,500

Calculation of annual ordering cost at (EOQ = 200):

Annual ordering cost=4,800200×120=24×120=$2,880

Calculation of purchase cost:

Purchase cost=4,800×300=$1,440,000

Calculation of total cost at (EOQ = 200):

Total cost=1,440,000+3,500+2,880=$1,446,380

The total cost at the (EOQ = 200) is $1,446,380

Calculation of difference in cost:

The total cost at (EOQ = 181) is $1,566,350. The total cost at (EOQ = 200) is $1,446,380. Therefore (EOQ = 200) has lesser cost ($1,446,380 < 1,566,350).

Hence, the optimal order quantity is 200 units with the minimum annual cost of $1,446,380

Monthly demand (d)= 400 / month

Holding cost (H) = $35 / unit / year

Ordering cost (S) = $120 / order

Purchase price (P) = $350 / chip

Annual demand (D)=Monthly demand×12 months=400×12=4,800

Price structure:

Quantity purchased	Price / unit
1 – 99 units	$350
100 – 199 units	$325
200 or more units	$300

Formula to calculate EOQ:

EOQ=2×D×SH

Formula to calculate annual holding cost:

Annual holding cost=EOQ2×H

Formula to calculate annual ordering cost:

Annual ordering cost=DEOQ×S

Formula to calculate purchase cost:

The obtained EOQ value is in the range of (100 – 199 units). Hence, the price of that range will be used for calculation.

Calculation of values at (EOQ = 188):

Calculation of annual holding cost at (EOQ = 188):

Annual holding cost=1882×(10%×325)=94×32.5=$3,055

Calculation of annual ordering cost at (EOQ = 188):

Annual ordering cost=4,800188×120=25.53×120=$3,064

Calculation of purchase cost:

Purchase cost=4,800×325=$1,560,000

Calculation of total cost at (EOQ = 188):

Total cost=1,560,000+3,055+3,064=$1,566,119

The total cost at the (EOQ = 188) is $1,566,319.

Calculation of values at discount quantity (200):

The next price break after the EOQ at 188 units is (200 or more units). The price of that range will be used in the following calculation.

Calculation of annual holding cost at (EOQ = 200):

Annual holding cost=2002×30=100×30=$3,000

Calculation of annual ordering cost at (EOQ = 200):

Annual ordering cost=4,800200×120=24×120=$2,880

Calculation of purchase cost:

Purchase cost=4,800×300=$1,440,000

Calculation of total cost at (EOQ = 200):

Total cost=1,440,000+3,000+2,880=$1,445,880

The total cost at the (EOQ = 200) is $1,445,880

Calculation of difference in cost:

The total cost at (EOQ = 188) is $1,566,319. The total cost at (EOQ = 200) is $1,445,880. Therefore (EOQ = 200) has lesser cost ($1,445,880 < 1,566,319).

Hence, the optimal order quantity is 200 units with the minimum annual cost of $1,445,880.

Answer 19

Explanation of Solution

Given information:

Monthly demand (d)= 400 / month

Holding cost (H) = 10 % of purchase price of the price structure

Ordering cost (S) = $120 / order

Purchase price (P) = $350 / chip

Annual demand (D)=Monthly demand×12 months=400×12=4,800

Price structure:

Quantity purchased	Price / unit
1 – 99 units	$350
100 – 199 units	$325
200 or more units	$300

Formula to calculate EOQ:

EOQ=2×D×SH

Formula to calculate annual holding cost:

Annual holding cost=EOQ2×H

Formula to calculate annual ordering cost:

Annual ordering cost=DEOQ×S

Formula to calculate purchase cost:

Purchase cost=D×P

Formula to calculate total cost:

Total cost=Purchase cost+Annual ordering cost+Annual holding cost

Calculation of EOQ at each price structure:

EOQ at price = $350

EOQ1=2×4,800×120(10%×350)=1,152,00035=32,914.285=181 units

EOQ at price = $325

EOQ2=2×4,800×120(10%×325)=1,152,00032.5=35,446.15=188 units

EOQ at price = $300

EOQ3=2×4,800×120(10%×300)=1,152,00030=38,400=196 units

EOQ = 181, cannot be bought at the price of $350. EOQ = 196 cannot be bought at the price of $300.

Hence, the EOQ is 188 units.

The obtained EOQ value is in the range of (100 – 199 units). Hence, the price of that range will be used for calculation.

Calculation of values at (EOQ = 188):

Calculation of annual holding cost at (EOQ = 188):

Annual holding cost=1882×(10%×325)=94×32.5=$3,055

Calculation of annual ordering cost at (EOQ = 188):

Annual ordering cost=4,800188×120=25.53×120=$3,064
