In question 4, why did we consider the needed waiting for trucks from 6pm to 8am?
A mechanic at the Department of Maintenance makes minor repairs to faulty golf electric carts. The carts break down at an average rate of 4 carts per day and breakdowns are distributed according to the Poisson distribution. The mechanic can service an average of 6 carts per day with a repair time distribution that approximates a negative exponential distribution. Assume an 8 hour day. a- What is the utilization rate for the mechanic? b- What is the average time in hours that a cart is out of service?

The Corner Cleaners 24-hour laundromat has 16 washing machines., A machine breaks down every 20 days (exponentially distributed). The repair service the laundromat contracts takes anaverage of one 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 they charge $10 more per hour than the current repair service. Currently, how long does the laundromat have to wait for its equipment to be repaired? days, (Round your answer to 2 decimal places, the tolerance is +/- 0.05.) What is the cost of equipment downtime? | (Round your answer to 2 decimal places, the tolerance is +2.5) %24
Suggest THREE (3) methods that an operations manager can adapt to enhance their customers' waiting experience rather than simply reducing the waiting time.
An ofi ce employs several clerks who create documents and one operator who entersthe document information in a computer system. The group creates documents at a rateof 25 per hour. The operator can enter the information with an average exponentiallydistributed time of two minutes. Assume the population is ini nite, arrivals are Poisson,and queue length is ini nite with FCFS discipline.a. Calculate the percentage utilization of the operator.b. Calculate the average number of documents in the system.c. Calculate the average time in the system.d. Calculate the probability of four or more documents being in the system.e. If another clerk were added, the document origination rate would increase to 30 perhour. What would the expected average number of documents in the system become?Show why.
