Modern Geomatics Technologies and Applications

Central agent: The central agent is responsible for identifying the nearest search agent, final evaluation
between different subgroup agents (searchers), announcing the task assigned to search agents, and being
responsible for assigning tasks to agents.
Search agent: Search agent is responsible for searching the environment to find the victims, responsible for
holding the action (in CNP), obtaining the propose of the sub-group agents and sending the decision made in
group to the central agent as well as arranging the appropriate agents for execution along with the duration of the
work for each agent.

Rescue agent: The rescue agent is responsible for rescuing injured individuals from rubbles, communicating
with the search agent, finding the most appropriate medical team, and assigning the task to the search agent.

Medical agent: The medical agent is responsible for providing medical services, moving the victims if it is
necessary and providing essential medical care to the hospital.

Hospital agent: The hospital agent accommodates the injured individuals and treats them.
After creating the model, assumptions were made and adequate parameters were chosen. Therefore, a set of
parameters along with their potential values were defined in order to express the model components’ properties
to deal with their characterization and dynamics, as well. The successful implementation of multi-agent systems
extremely depends on the availability of appropriate technology (e.g., programming languages, software libraries,
and software development tools) to implement the relevant concepts. AnyLogic7.0.2 software and Java
programming classes have been used to implement the post-earthquake rescue simulation system, which allows
the use of GIS data by adding other classes to it.

4. Results and discussion

ArcGIS10.4.1 software was used to estimate the 7-magnitude earthquake of the North Tabriz fault in the city
of Tabriz. In this software, first the distance map of the fault was prepared and then by using the raster calculator
tool, the output of the equations presented in section 3-1 was prepared as a raster file. Using the earthquake
intensity map at the location of buildings and vulnerability cures, the amount of damages resulted for buildings
was calculated (Fig. 4).
