The Quick Wash 24-hour Laundromat has 16 washing machines. A machine breaks down every 20 days (exponentially distributed). The repair service with which the Laundromat contracts takes an average of 1 day to repair a machine (exponentially distributed). A washing machine averages $5 per hour in revenue. The Laundromat is considering a new repair service that guarantees repairs in 0.50 day, but it charges $10 more per hour than the current repair service. Should the Laundromat switch to the new...

The manager has the option of replacing these three repairmen with a super-repairman whose salary is equal to the total of...
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...
