A pediatric practice has five physicians. Historically, patients were assigned to one physician and these patients always were treated by the same physician. For example, Alice’s patients always visited her (for “well visits” and “sick visits”) and never interacted with the other physicians. However, the practice has decided to change how it sees patients. Now patients will be seen by whoever is available (i.e., not treating patients). Based on our discussion of queuing theory, which of the following three outcomes is/are likely to occur due to this change? 

i. The coefficient of variation of patient interarrival times will increase. 

ii. The utilization of the physicians will increase. 

iii. The average number of patients actually with a physician (that is, “inventory in process”) will increase. 

a. I only 

b. II only 

c. III only 

d. I and II only 

e. I and III only 

f. II and III only 

g. All of them (I, II, and III) 

h. None of them (neither I, II, nor III)
