...Software entities that assist people and act on their behalf
...Software “robots”
Goal-drivenhave a purpose andact in accordance withthat purpose until it isfulfilled
Communicativeable to interact andcommunicate with users and other agents
Proactivedetect changes in theirenvironment and react to those in a timely mannerby answering to events and initiating actions
Autonomouscan have control over their own actions and be able to work and launch actions independent of the user or other actors
Learninghave the ability tolearn from experiencesin their environment

Simple Agent Example
Agent, find me the book “War and Peace,”
and I need it tomorrow
Does the agent understand
buying books?

Why Agents?
Simulation techniques are thorough, but can take hours to run
Mathematical methods can be very fast, but make broad assumptions
Both require extensive training and validation Agents provide the capability to:
– Bridge the gap between simulation and Mathematical methods
– Easy to use and develop– Easy connection of other systems– Move from analysis to action

Agent Based Network Model
Simulation and analytic models
Control over local and global behavior
Easy to setup and adapt From deployed MABES agent-based network model
