| Summary: | Tsunami is a wave of trains which travels with high speed on the sea surface.
This travelling wave is caused by the displacement of a large volume of water
after the occurrence of an underwater earthquake or volcano eruption. The
speed of tsunami decreases when it reaches the sea shore along with the
increase of its amplitudes. Two large tsunamis had occurred in Indonesia with
huge casualties and large damage. Indonesian Tsunami Early Warning System
has been installed along the west coast of Sumatra. This early warning system
will give about 10-15 minutes to evacuate people from high risk regions to
the safe areas. Here in this nal project, an mathematical model for Tsunami
evacuation is presented with Padang City as a study case. In the model, the
safe areas are chosen from the existing high rise buildings, low risk region with
relatively high altitude and (proposed to be build) ring road which are located
in the radius of approximately 1 km from each gathering points. The model is
formulated as an optimization problem with the total evacuation time as the
objective function. The constraints consist of maximum allowable evacuation
time in each route, maximum capacity of each safe area, and the number of
people to be evacuated. The optimization problem is solved numerically using
linear programming method with Matlab. Numerical results are shown for
various evacuation scenarios for the city of Padang. |
