The Java Agent-Based Modelling (JABM) toolkit is a Java framework for building agent-based models using a discrete-event simulation framework. It was developed by Steve Phelps for research carried out at the Centre for Computational Finance & Economic Agents (CCFEA).
An overview of JABM can be found in the following working paper
The easiest way to install JABM is to import the ZIP file as an existing project into the Eclipse IDE. See these step-by-step instructions. The Spring IDE plugin for Eclipse is useful for editing model configurations.
