Chapter 5, Problem 1P
Bill’s Barbershop has two barbers available to cut customers’ hair. Both barbers provide roughly the same experience and skill, but one is just a little bit slower than the other. The process flow in Figure 5.9 shows that all customers go through Steps Bi and B2 and then can be served at either of the two barbers at Step B3. The process ends for all customers at Step B4. The numbers in parentheses indicate the minutes it takes that activity to process a customer.
- How long does it take the average customer to complete this process?
- What single activity is the bottleneck for the entire process?
- How many customers can this process serve in an hour?

- . The School of Dentistry at Penn provides general dental care to residents of Philadelphiaon a walk-in basis. Upon arrival, customers first provide health-relevant informationsuch as personal health records and insurance provider to a receptionist who entersthe information into the computer system for the dentist to see. A dental assistant thentakes an X-ray of the patient. A dentist then performs the checkup and discusses anyissues with the patient.

- Miss Felicia is the owner of a homestay business under the registered name of FNB Hospitality Enterprise. The business runs ten units of homestay in Kuala Lumpur and Selangor. In addition to homestays bookings, Miss Felicia also receives bookings for events and meals delivery during the guests’ stay. Recently, due to the lifting of the movement control order (MCO), there are increasing requests and bookings made by the guests. Miss Felicia is overwhelmed with the processes since she is using a manual system in managing all bookings and requests, which are recorded in a logbook. There were incidents of overlapping and missing bookings and payments received. On several occasions, meals were not delivered as promised.

Winston Martin (an allergist) has an excellent system for handling his regular patients who come in just for allergy injections. Patients arrive for injection and fill out a name slip, which is then placed in an open slot that passes into another room staffed by one or two nurses. The specific injections for a patient are prepared, and the patient is called through a speaker system into the room to receive the injection. At certain times during the day, patient load drops and only one nurse is needed to administer the injections. Let’s focus on the simpler case of the two—namely when there is one nurse. Also, assume that patients arrive in a Poisson fashion and the service rate of the nurse is exponentially distributed. During this slower period, patients arrive with an interarrival time of approximately three minutes. It takes the nurse an average of two minutes to prepare the patients’ serum and administer the injection.a. What is the average number you would expect to see in Dr.…arrow_forward
