Having too much capacity is just problematic as not having enough capacity. Select one: True False
A mom and pop car wash with 1 drive through lane gets an average of 4 cars per hour, with a Poisson distribution. The washing and drying process has a mean of 12 minutes, M= exponentially distributed, and a car cannot enter the lane until the car in front of it is finished drying (there can only be one car in the lane at one time). Due to the location, there is only space enough to hold 5 cars in line waiting to get washed. However, they rent space from the empty lot next door that is large enough to hold as many cars as needed. They decided to rent a section that will hold only 3 cars. a) If they decide to rent a section that will hold 3 cars, what will you solve for to determine the probability that they will still turn cars away? b) They promise each customer their money back ($10) if it takes longer than 30 minutes to get their car washed (from the time they enter). They are open 8 hours per day. How much money can they expect to give away per day?
A) During registration at State University every semester students in the college of business must have their courses approved by the college advisor. It takes the advisor an average of 12 minutes to approve each schedule and students arrive at the advisor's office at a rate of 3 per hour, according to A Poisson Distribution. Calculate the operating characteristics (Po, L, Lq, W, Wq and Pw) for this system. B) The dean from the college has recieved alot of complaints from students about the length of time they must wait to have their schedule approved. The dean therefore add an additional college advisor to the system describe in this problem so that it is now a multi-server queuing system with two channels. Calculate the operating characteristic channel describe in part A.

Under ideal conditions, a service bay at a FastLube can serve 6 cars per hour. The effective capacity and efficiency of a Fast Lube service bay are known to be 5.5 and0.880, respectively. What is the minimum number of servicebays Fast Lube needs to achieve an anticipated servicing of200 cars per 8-hour day?
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 machines per workday, with a repair time distribution that resembles the negative exponential distribution. a) The utilization rate of this service system (round your response to two decimal places)
If Melanie adds an additional server at Clean Machine carwash, the service rate changes to an average of 16 cars per hour.Th e customer arrival rate is 10 cars per hour. Melanie has askedyou to calculate the following system characteristics:(a) Average system utilization(b) Average number of customers in the system(c) Average number of customers waiting in line
Uberya Towing Services repair vehicles that break down at an average 8 vehicles per day. The mechanic crew can service an average of 11 vehicles per day. How many vehicles are likely to be in the system at any one time? The crew cost is approximately Php 900 per day. The cost associated with lost productivity from the breakdown is estimated at Php500 per vehicle per day. if an additional Service crew is added, What is the Expected or Total Cost (Waiting +Service Cost)?
A post office has a single line for customers waiting for the next available postal clerk. There are two postal clerks who work at the same rate. The arrival rate of customers follows a Poisson distribution, while the service time follows an exponential distribution. The average arrival rate is three per minute and the average service rate is two per minute for each of the two clerks. How long does the average person spend waiting for a clerk? 1.143 minutes 3.429 minutes 1.929 minutes 0.643 minute
