14. A small town's hospital wanted to an analysis about the ambulance number that they own/needto own. Requests for ambulance is 0,45 per hour and tend to follow Poisson-distribution. Traveland assistance time averages two hours per call. There is no assumption regarding the distributionof service time.a. What are the arrival and service ratesb.Compute the average number of customers being served at any timec. Calculate the system utilization for total number of server values of M=1,2 and 3d. Suppose someone made a day long observation and concluded that the average queue lengthis 1,7 requests. Then please calculate the average number of people in the system.

To analyze the number of ambulances needed, we can use queuing theory.

Answered: a. What are the arrival and service…

Ali Baba‘s Car Wash Service Centre is open 6 days a week, but its busiest day isalways on Sunday. From the previous data, Ali Baba estimates that dirty carsarrive at the rate of one every two minutes. One car at a time is cleaned in thisexample of a single-channel waiting line. Assuming Poisson arrivals andexponential service times, find the following: a.Compute the average number of cars in line. b.Calculate the value of probability that there are no car in the system. c.Compute the average time that a car spends in the system.
Please do not give solution in image format thanku A drive-in market has one checkout counter where one employee operates the cash register. The combination of the cash register and the operator is the server in this queuing system; the customers who line up at the counter to pay for their selections form the waiting line. Customers arrive at a rate of 24 per hour according to a Poisson distribution, and service times are exponentially distributed with a mean rate of 30 customers per hour. What are the operating characteristics for this waiting line system?
