Virginia's Ron McPherson Electronics Corporation retains a service crew to repair machine breakdowns that occur on an average of λ = 4 per 8-hour workday (approximately Poisson in nature). The crew can service an average of µ = 6 machinesper workday, with a repair time distribution that resembles the negative exponential distribution.a) The utilization rate of this service system = 0.67 (round your response to two decimal places).b) The average downtime for a broken machine = 0.50 days (round your response to two decimal places).c) The average number of machines waiting to receive service at any given time = 1.33 machines (round your response to three decimal places).d) The probability that there is more than one machine that is in the system = 0.444 (round your response to three decimal places).The probability that there are more than two machines that are in the system = 0.296 (round your response to three decimal places).The probability that there are more than three machines that are in the system=(round your response to three decimal places).

130) please please help me with this! Owners of a local restaurant are concerned about their ability to provide quality service as they continue to grow and attract more customers. They have collected data from Friday and Saturday nights, their busiest times of the week. During these time periods, about 106 customers arrive per hour for service. Given the number of tables and chairs, and the typical time it takes to serve a customer, the owners estimate they can serve, on average, about 162 customers per hour. Use Exhibit 4.6. Furthermore, the owners anticipate that in one year their demand will double as long as they can provide good service to their customers. a. Currently, during these nights, are they in the zone of service, the critical zone, or the zone of nonservice? EXIBIT IS THE PICTURE ADDED O Critical zone O Zone of service O Zone of nonservice b. Next year, after demand doubles, what must the service capacity increase to (at minimum) to stay out of the critical zone?Note:…

1. (First System) A crew of mechanics at the NCDOT repair NCDOT vehicles that break down at an average rate of λ = 4 vehicles per day. The crew can service an average of µ = 5 vehicles per day. The crew cost is $400 per day. A bureaucrat in Raleigh has determined the cost associated with lost productivity due to breakdowns is $300/day. (This includes the entire time the vehicle is unavailable—from the time it breaks down until the time it is back on the road.) 2. (Second System) This same bureaucrat thinks it would be a good idea to have two repair crews instead of one. Vehicles still break down at the same rate of 4/day. Each crew can still service 5 /day. Assume that each crew handles half of the breakdowns. Each crew costs $400/day. The cost associated with the lost productivity of an idle vehicle is still $300/day. Which system do you recommend and why?
A small popular restaurant at an interstate truck stop provides priority service to truckers. The restaurant has ten tables where customers may be seated.

Question 1 options: 0.27. 0.52. 0.88. 1.36. 1.75.
