A bicycle component manufacturer produces hubs for bike wheels. Two processes are possible for manufacturing, and the parameters of each process are as follows: Process 1 Production rate Daily production time Process 2 35 parts/hour 4 hours/day 20% 15 parts/hour 7 hours/day 9% Percent parts rejected Assume that the daily demand for hubs allows all defect-free hubs to be sold. Select the process that maximizes profit per day if each part is made from $4 worth of material and can be sold for $30. Both processes are fully automated, and variable overhead cost is charged at the rate of $40 per hour.

Merrimac Manufacturing Company has always purchased acertain component part from a supplier on the East Coast for$50 per part. The supplier is reliable and has maintained thesame price structure for years. Recently, improvements in operations and reduced product demand have cleared up somecapacity in Merrimac’s own plant for producing componentparts. The particular part in question could be produced at$40 per part, with an annual fixed investment of $25,000.Currently, Merrimac needs 300 of these parts per year.a. Should Merrimac make or buy the component part?b. As another alternative, a new supplier located nearby isoffering volume discounts for new customers of $50per part for the first 100 parts ordered and $45 per partfor each additional unit ordered.

A bagel store orders cream cheese from three suppliers, Cheesy Cream Corp. (CCC), Super Smooth & Sons (SSS), and Bagel's Best Friend Co. (BBF). One month, the total order of cheese came to 100 tons. (The store does do a booming trade.) The costs were $80, $50 and $65 per ton from the three suppliers respectively, with the total cost amounting to $6,710. Given that the store ordered the same amount from CCC and BBF, how many tons of cream cheese were ordered from each supplier?

Residents of Mill River have fond memories of ice skating at a local park. An artist has captured the experience in a drawing and is hoping to reproduce it and sell framed copies to current and former residents. He thinks that if market is not good, he could sell 400 copies of the version at Rs.125 each. If the market is good, he would only sell 300 at Rs. 90 each. He could make a deluxe version of the same drawing instead. He feels that if the market were not good he could sell 500 copies of the deluxe version at Rs.100. If the market is good, he would only sell 400 copies at Rs.70 each. In either case, production costs would be approximately Rs.35,000. He could also choose to do nothing at this time. If he believes there are a 40% probability of a good market, and 60% probability of not good market, what should he do? Why?
