No. of servers (s) | P0 | Lq | Ls | Cost of mechanics = Ls *30 |
Cost of servers = s * 20 |
Total cost per hour |
2 | 0.3333 | 0.3333 | 1.3333 | 40.0 | 40.0 | 80.0 |
3 | 0.3636 | 0.0455 | 1.0455 | 31.4 | 60.0 | 91.4 |
4 | 0.3673 | 0.0068 | 1.0068 | 30.2 | 80.0 | 110.2 |
The table above illustrates that s = 2 is the minimum cost situation.

The parts department of a large automobile dealership has a counter used exclusively for mechanics’ requests for parts. The time between requests can be modeled by a negative exponential distribution that has a mean of five minutes. A clerk can handle requests at a rate of 15 per hour, and this can be modeled by a Poisson distribution that has a mean of 15. Suppose there are two clerks at the counter. On average, how many mechanics would be at...
In an auto repair shop, mechanics requiring parts for auto repair present their request forms at the parts department counter. A parts clerk fills a request while the mechanics wait. Mechanics arrive at an average rate of 35 per hour (Poisson). A clerk can fill requests in 6 minutes (exponential). Suppose that the manager of the parts department decides to have 4 parts clerks. 1: What is the probability that a new request will have to wait for service? 2:...
C) Janson's is considering
adding a second clerk to take calls. the store's cost would be the
same $12 per hour. The total cost ( service cost + waiting cost) =
$___per hour (round your response to two
decimal places)
By hiring the second clerk, the total cost savings per hour for
Janson's = $___ per hour (round your response to two
decimal places)
Janson's Department Store in Stark, Ohio, maintains a successful catalog sales department in which a clerk...
QUESTION 1 Customers arrive at a hair salon according to a Poisson process with an average of 16 customers per hour. Which of the following is most likely true, based on this information: a. The hair salon serves customers on a walk-in basis (rather than by appointment times) b. If 10 customers arrive in the first hour, it is likely that 22 customers will arrive in the next hour. c. If the salon can serve an average of 20 customers...
subject: operations research When customers arrive at Cool's Ice Cream Shop, they take a number and wait to be called to purchase ice cream from one of the counter servers. From experience in past summers, the store's staff knows that customers arrive at a rate of 150 per hour on summer days between 3:00 p.m. and 10:00 p.m., and a server can serve 1 customer in 1 minute on average. Cool's wants to make sure that customers wait no longer...
Will runs a dog grooming service, and has asked you to analyze the current 'line situation'. He has gathered data and calculated that he can groom a dog in about 10 minutes, based on a negative exponential distribution. He also noted that about 3 dogs arrive to his shop per hour, during all operating hours, based on a Poisson distribution. How long, on average, will a dog wait for grooming? ["10 minutes", "1 minute", "16.67 minutes", "20 minutes"] ...
At the Boise Cascade Corporation, lumber mill logs arrive by truck and are scaled (measured to determine the number of board feet) before they are dumped into a log pond. The figure below shows the basic flow. Scaling Stations Trucks Enter Log Pond The mill manager must determine how many scale stations to have open during various times of the day. If too many stations are open, the scalers will have excessive idle time and the cost of scaling will...
