Holstein Computing manufactures an inexpensive audio card (Audio Max) for assembly into several models of its microcomputers. The annual demand for this part is 100,000 units. The annual inventory carrying cost is $5 per unit and the cost of preparing an order and making production setup for the order is $750. The company operates 250 days per year. The machine used to manufacture this part has a production rate of 2000 units per day.

a. Calculate the optimum lot size. (5 pts)b. How many lots are produced in a year? (5 pts)c. What is the average inventory for Audio Max? (5 pts)d. What is the annual cost of preparing the orders and making the setups for Audio Max? (5 pts)

a. Calculate the optimum lot size. (5 pts)

Annual demand = 100,000 unitsSetup cost = $750Carrying cost= $ 5 per unitDaily demand rate = 2000/5 = 400 units dailyDaily production rate = 2000

Q* = 2DS

H (1-d/p)

= 2 x 100,000 x 750

5 (1- 400/2000

= 150,000,000

5 (0.8)

= 37,500,000

= 6,123.7 or 6124 units

Therefore the optimal lot size would be 6124 units

b. How many lots are produced in a year? (5 pts)

N = Demand / Order quantity

N = 100,000/ 6124 = 16.33 lots per year

Therefore 16.33 lots size are produced in a year

c. What is the average inventory for Audio Max? (5 pts)

The maximum inventory = Q (1-d/p)

6124 x (1- 400/2000) = 4899 units

Annual inventory level = maximum inventory level / 2

average inventory = 4899/2 = 2,449.5 units

Therefore the average inventory for Audio Max is 2,499.5 units

d. What is the annual cost of preparing the orders and making the setups for Audio Max? (5 pts)

Annual cost = D/Q x S + average inventory x H

= 100,000/6124 x 750 + 2,449.5 x 5

= $12,247 + $12,248

= $24,495

Therefore the annual cost of preparing the orders and making the setups for Audio Max is $24,495

#4

A toy manufacturer makes stuffed kittens and puppies which have relatively lifelike motions. There are three different mechanisms which can be installed in these "pets." These toys will sell for the same price regardless of the mechanism installed, but each mechanism has its own variable cost and setup cost. Profit, therefore, is dependent upon the choice of mechanism and upon the level of demand. The manufacturer has in hand a forecast of demand that suggests a 0.2 probability of light demand, a 0.45 probability of moderate demand, and a probability of 0.35 of heavy demand. Payoffs for each mechanism-demand combination appear in the table below.

Demand Wind-up action Pneumatic action Electronic actionLight $250,000 $90,000 -$100,000Moderate 400,000 440,000 400,000Heavy 650,000 740,000 780,000

Light demand (0.2) $250,000

Wind-up Moderate demand (0.45) $400,000

EMV = $457,500 Heavy demand (0.35) $650,000

Light demand (0.2) $90,000

2 Pneumatic Moderate demand (0.45) $440,000

EMV = $475,000 Heavy demand (0.35) $740,000

Light demand (0.2) $-100,000

Electronic Moderate demand (0.45) $400,000

EMV = $433,000 Heavy demand (0.35) $780,000

1. Wind-up action = 0.2 x 250,000 + 0.45 x 400,000 + 0.35 x 650,000 = $457,5002. Pneumatic action = 0.2 x 90,000 + 0.45 x 440,000 + 0.35 x 740,000= $475,0003. Electronic action = 0.2 x -100,000 + 0.45 x 400,000 +0.35 x 780,000= $433,000

Therefore the optimal decision for the manufacturer would be the pneumatic which is $475,000
