Agent-Based Modeling and Simulation II: Actions, Cohorts and Analysis of Results (System Dynamics Modeling with Vensim)

EDITION 2025

In the book "Models based on Agents I" you have learned to:

1.- Install the software and create a model.
2.- Define the equations, using functions and tables.
3.- Simulate the model by viewing the numerical and graphic results.
4.- Create attributes, collections and aggregates.
5.- Add references.
6.- Define temporary parameters for the simulation.
7.- Import initial data.
8.- Import time series of data.

In this book II, you learn to:

1.- Consolidate the import of data.
2.- Create new entities with actions and triggers.
3.- Design lots and cohorts of entities.
4.- Do Sensitivity Analysis.
5.- Optimization of the results.
6.- Calibration of the variables.
7.- See the results on a X-Y diagram.
8.- Integrate the model with GIS files.
