92 Benny the Barber owns a one-chair shop. At barber college, they told Benny that his customers would exhibit a Poisson arrival distribution and that he would provide an exponential service distribution. His market survey data indicate that customers arrive at a rate of 2.5 per hour. It will take Benny an average of 20 minutes to give a haircut. Based on these figures, find the following: a. The average number of customers waiting Note: Round your intermediate calculations to 3 decimal places and final answer to 2 decimal places. b. The average time a customer waits.

n Canada, many people have complained that the waiting time in hospital emergency is oftenvery long. (Here, the waiting time is defined as the time from arrival to departure.)A typical service process in a hospital emergency has several stages:1. When patients arrive, they register personal information (such as health card number,reasons to be there) in a computer. Then, patients wait in an open waiting area.2. There is often one or two doctors whose offices are at the side of the open waiting area.The doctor(s) talks with the patients one by one to have preliminary diagnosis andprovide some help.3. Then, the patients wait in the same waiting area.4. A nurse arranges (part of) the patients to a closed area to wait for doctors.5. A nurse arranges the patients waiting in the closed area to individual rooms to wait fordoctors.6. A doctor helps the patients individually. Then, patients leave individually.According to your simulation, what is the bottleneck of reducing the waiting time?…
DEMU 2103, va assignmen QUESTION 3 Metropolitan General Hospital is a city-owned and operated public hospital. Its emergency. room is the largest and most prominent in the city. Approximately 70% of emergency cases in the city come or are sent to Metro General's emergency room. As a result, the emergency room is often crowded and the staff is overworked, causing concern among hospital administrators and city officials about the quality of service and health care the emergency room is able to provide. One of the key quality attributes administrators focus on is patient waiting time that is, the time between when a patient checks in and registers and when the patient first sees an appropriate medical staff member. Hospital administration wants to monitor patient waiting time using statistical process control charts. At different times of the day over a period of several days, patient waiting times were recorded at random with the following results: Sample 1 2 3 4 5 6 7 8 9 10 1 27 22 16…

Question 9 In Littlefield Labs, each order is processed at three stations before being completed and sent to customers. Suppose at the peak demand (i.e., after 180 days in the game) the flow rate is 10 orders per day. And the average inventory at station 1, station 2 and station 3 are 72, 65 and 70 kits, respectively (these include kits being processed as well as those in queues). What is the average lead time (in hours) o complete an order? Please specify your answer in at least 2 decimal points. (Remember 1 order has 60 kits, each day has 24 hours). Next
