Agent-Based (Individual-Oriented) Models - Simulating Fish School
and Hospital Emergency Departments:
Computational simulation has been used as a powerful tool to
represent the dynamical behavior of systems based on complex models. In
Individual-oriented (IoM) / Agent Based (ABM) Models, the unit of the
system is the individual, so the group’s heterogeneity can be
represented through the differentiated behavior of each individual.
Therefore, “individuals are the building blocks of ecological system.
The properties and behavior of individuals determine the properties of
the systems they compose”. This means the ABM/IoM modeller defines the
behavior at the agent level and the global, or system, behavior
emerges as a result of the interactions of the many individual agents.
Agent Based/Individual-oriented Modeling has its main roots in
modeling individual decision making, human social interactions, and the
organisational behavior of biological systems.
The development of the Fish School simulator includes the possibility of
working with large models that include large numbers of fish (> 10M of
individuals), predators and obstacles in the simulated world. In
addition to the classical numerical model for the Fish School
simulation, we have also implemented a "fuzzy model" for this
simulation. Experiments performed demonstrated that our model represents
the real behavior of Fish School.
Hospital emergency departments are complex systems, characterized by
uncertainty and variability, often operating with limited resources and
high demands. Simulations of these departments have proven to be
efficient tools in improving their performance in certain circumstances,
however the human aspect is often overlooked in the application of
modeling and simulation to this field. One of our projects is applying
agent-based modeling techniques to the simulation of hospital emergency
departments. The work performed included system analysis and a
preliminary model, showing the advantages of this technique.
