Agent-Based Modeling?
Sadly, no.

Then what is it?
• Simulation– The imitation of the operation of a real-world process or
system over time
Not to be confused with…
• Emulation– The replication of the behavior of a real-world process or
system

Benefits of Simulation
• Faster (maybe)
• Cheaper (maybe)
• Safer (most likely)

Simulation begins with a model…
• The “model represents the key characteristics or behaviors/functions of the selected physical or abstract system or process”
• Agent-based modeling (ABM) models “the actions and interactions of autonomous agents … with a view to assessing their effects on the system as a whole”

Verification and Validation
• Verification– “Am I building the thing right?”– Is the functionality implemented correctly?
• Validation– “Am I building the right thing?”– Does the behavior of the simulated system match the
behavior of the real one?– Does the simulation produce the needed output?

Applications of Simulation
• Training and education• “What-if?” analysis and prediction• Testing• Studying complex systems
– Biology– Ecology– Social/network science
