Little's Law Example At the COVID-19 testing center 90 people arrive each hour to be tested. Anyone who wants to be tested waits in line for an average of 10 min before registering with the triage nurse. Registration takes 2 min and from there patients are triaged into symptomatic or asymptomatic. Symptomatic patients are sent to area A and asymptomatic are sent to area B. In area A there is space for 2 people to wait before being seen by a nurse. The average wait time is 5 min. It takes a nurse 30 seconds to swab, but it typically takes 30 seconds for the patient to get positioned at the nurse's station before the swab, 1 min for the nurse to record the information after the swab and 3 min for the station to be cleaned before the next patient can enter. There are two nursing stations in area A. In area B, the average wait time is 1 min before being seen by a paramedic who swabs you in your seat. It takes 30 seconds for them to swab the patient and another 1 min for them to record the patient's information before the patient can leave. Draw the process. A) What percentage of patients are symptomatic? B) How many people are waiting to be triaged at any point in time? C) What is the average number of people in the Covid testing center at any given time? D) If someone knows they are symptomatic how long should they expect to wait to get tested? E) How many paramedics are required if they can only swab one patient at a time? F) The Ontario government pays $25 per symptomatic test and $15 per asymptomatic test completed, as well as providing the actual tests. The testing center is open for 8 hours per day and has 2 tirage nurses, two testing nurses, 3 cleaning staff and the paramedics. Nurses are paid $45 per hour, cleaning staff are paid $17 per hour and the paramedics are paid $21 per hour. If the clinic pays $10 per test to have it processed by the lab and $400 a day in rent, what is the operating profit per hour of the clinic?
