ELVAC |
ELVAC (Elevator Evacuation) is an interactive computer
program that estimates the time required to evacuate
people from a building with the use of elevators and
stairs. It is cautioned that elevators generally are
not intended as a means of fire evacuation, and they
should not be used during fires. However, it is possible
to design elevator systems that for fire emergencies,
and ELVAC can be used to evaluate the potential performance
of such systems. ELVAC calculates the evacuation time
for one group of elevators. If a building has more than
one group of elevators, ELVAC can be run on each group
separately. Input consists of floor to floor heights,
number of people on floors, number of elevators in the
group, elevator speed, elevator acceleration, elevator
capacity, elevator door type and width, and various
inefficiency factors. The output is a table of elevator
travel time, round trip time, people moved, and number
of round trips for each floor plus the total evacuation
time. ELVAC was written in compiled BASIC by John H.
Klote and Daniel M. Alvord. |
