Video 4 – Assignment
• Suppose the patient arrival rate increases by 5%. Can the current system handle the
increase? What about 7%? 10%? Compare the expected time patients spend in the
system (by patient type) and the waiting times at each station for the baseline, +5%,
+7%, and +10% cases.
• Add an additional patient type (registration, lab, treatment, accounting, depart).
These patients arrive at the rate of 3 per hour. Can new system handle these new
patients (under the 4 scenarios above)? If not, what is your recommendation (be
specific)?
• Replace the free-space movement with paths and "layout" for a clinic (starting with
the single-source model). You can find a suitable layout on the internet or just make
one up (using “reasonable” distances between stations).
