$2\mathrm{.}1.$ Build a model for a medical clinic using Simio. The patients check$-$in at

reception, undergo a blood pressure test, and complete a doctor$$s

consultation. Interarrival times are exponentially distributed with a mean of $12$

minutes. The processing times are triangular$(4,7,10)$ at reception,

triangular$(3,5,7)$ for the blood pressure test, and triangular$(10,12,15)$ for the

doctor$$s consultation. The reception and the blood pressure test are managed

by one nurse each. The doctor consultations are handled by two doctors

available simultaneously. The clinic operates from $08$:$00$ to $16$:$00.$ Report on

the following:

$2\mathrm{.}1\mathrm{.}1.$ Time In System $($TIS$),$

$2\mathrm{.}1\mathrm{.}2.$ Utilization of the nurse and the doctors,

$2\mathrm{.}1\mathrm{.}3.$ Average and maximum number of patients in all queues.

$2\mathrm{.}1\mathrm{.}4.$ Justify the number of replications performed to achieve confidence in the

model results.
