Renaissance Clinic provides quick checkups for chronic diseases. At the time of a visit, a patient first checks in with the receptionist who directs the patient to be seen by either a nurse or Dr. Thompson. Some patients see both the nurse and the doctor.

For this case, we apply queuing theory to Dr. Thompson’s practice. The data below were collected over several days of typical activity.

Description	Expectations
Arrival rate of patients	20 per hour
Fraction of patients who see nurse	75%
Fraction of nurse patients who also see physician	20%
Service rate of receptionist	30 per hour
Service rate of nurse	20 per hour
Service rate of physician	10 per hour

 

 

 

 

 

 

 

 

 

 

 

Assume the waiting lines at the receptionist, nurse, and doctor are managed independently, each with a FCFS priority. For each of your answers, write a complete sentence stating the meaning of the result, for example, “The 90% utilization rate of the ice cream server is very high and will result in a long queue,” or “There are 20 people in the queue. They will need a lot of space.”

 

 

 

 

Assignment
