Click a room or triage desk to put its doctor/nurse on or off shift. Click a patient for details and fast-tracking.
Same queueing model as the 3D version: Poisson arrivals, triage nurses then doctors with ESI priority, lognormal treatment times, LWBS walk-outs. Reference: M/M/c Erlang C and Little's law L = λW; the theory ignores priorities, triage and walk-outs.
