  1. Supermodels and James Bond: How They Are Different From Agent-Based Modeling and Simulation Alexander S. Mentis 15 October 2013

  2. Agent-Based Modeling? Sadly, no.

  3. 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

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

  5. 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” (Source: Wikiknow-it-all)

  6. 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?

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