The service process includes five activities that are conducted inthe sequence described below ( the time required for each activity is shownin parenthesis):Activity 1: Welcome a guest and offer homemade herb tea (10 minutes)Activity 2: Wash and condition har (10 minutes)Activity 3: Neck, shoulder, and back stress release massage (10 minutes)Activity 4: Design and hair style and do the hair (25 minutes)Activity 5: Ring up the guest bill (5 minutes)Each activity has one employee dedicated to it. For the following questions,assume unlimited demand. Also assume that the employee at activity 1 onlyadmits new guests at the rate of the bottleneck.(a) Which resource is the bottleneck?(b) What is the capacity of the process?(c) What is the flow rate?(d) What is the utilization of the employee at activity 3(e) What is the cycle time?. 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. Depending on the day, patients might have to wait at any of theseresources. This concludes the process.
