Metalco is in the process of hiring a repairperson for a 10-machine shop. Two candidates are under
consideration. The first candidate can carry our repairs at the rate of 5 machines per hour and earns
$15 an hour. The second candidate, being more skilled, receives $20 an hour and can repair 8 machines
per hour. Metalco estimates that each broken machine will incur a cost of $50 an hour because of lost
production. Assuming that machines break down according to a Poisson distribution with a mean of 3
per hour and that repair time is exponential, which repairperson should be hired?

The Acme Machine Shop has five machines that periodically break down and require service. The average time between breakdowns for any one machine is 4 days, distributed according to an exponential distribution. The average time to repair a machine is 1 day, distributed according to an exponential distribution. One mechanic repairs the machines in the order in which they break down. Use q.xls. a. Determine the probability that the mechanic is idle. (Hint: Pn is given in q.xls, and is...
Virginia's Ron McPherson Electronics Corporation retains a service crew to repair machine breakdowns that occur on an average of λ 3 per 8-hour workday (approximately Poisson in nature). The crew can service an average of μ-6 machines per workday, with a repair time distribution that resembles the negative exponential distribution. a) The utilization rate of this service system50 (round your response to two decimal places) ) The average downtime for a broken mchnedays(round your response to two decimal places Enter...
A manager is trying to decide whether to buy one machine or two. If only one machine is purchased and demand proves to be excessive, the second machine can be purchased later. Some sales would be lost, however, because the lead time for delivery of this type of machine is six months. In addition, the cost per machine will be lower if both machines are purchased at the same time. The probability of low demand is estimated to be 0.20...
1) You manage a fabrication department. Your department needs to machine 1,000 brackets to be delivered to the assembly department for the assembly line which will begin working in 72 hours at 6 am. You will hire temporary help to fabricate the brackets. One unskilled candidate can be trained and get the job done in 72 hours @ $12.00 per hour. Another candidate who already has the skills can do the job in 40 hours @ $25.00 per hour. The...
