When the number of the triage staff is increased to reduce waiting time for triage operation, the
number of medical personnel should be increased accordingly or alternative treatment areas should
be constructed parallel to increasing number of triage staff, since it was discovered that waiting times
in trauma and observation rooms will also increase. Total casualty fraction also affects waiting times,
and at the maximum level of this factor, large number patients lose their lives in the triage and
treatment queues are at the large numbers. Significant effects of total casualty fraction were found
both on ambulance waiting time and waiting time for treatment. Therefore the analysis of the results
shows that before the actual disaster, any activity which will decrease the total casualty fraction will
be highly effective in reducing total loss.
