L$016-4$

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?

A$.$ The coefficient of variation of patient interarrival times will increase.

B$.$ The utilization of the physicians will increase.

C$.$ The average number of patients actually with a physician $($that is$,$ "inventory in process"$)$ will increase.

a$.$ A only

b$.$ B only

c$.$ C only

d$.$ A and B only

e$.$ A and C only

f$.$ B and C only

g$.$ All of them $($A$,$ B$,$ and C$)$

h$.$ None of them $($neither A$,$ B$,$ nor C$)$
