DisCo-BaTS

Distributed Component-Based Traffic Simulation

A framework for highly flexible scenario modeling and direct simulation execution
without the need for manual model-transformations or adjustments of the simulation application.

Centered around a unified meta-model that explicitly targets scenario-based simulation testing of
various software-based systems and system-components, which can be located both locally and remotely.

Modules

• plugins discobats own custom plugins that are needed for builds should be located here
  • maven-plugins
    • mvn-jaxb-index-builder plugin that build the jaxb.index file during the maven build process for a model library. the jaxb.index is needed to provide JAXB with the knowledge what classes the model contains and where those are located. that way JAXB is able to unmarshall those classes from a scenario XML description that references the library.

Important

This framework was developed as part of a doctoral thesis submitted on February 19, 2026, titled "Flexible Komponentenbasierte Modellierung und Simulation von Szenarien für die Verifizierung und Validierung automatisierter maritimer Fahrsysteme" (eng.: "Flexible component-based modeling and simulation of scenarios for the verification and validation of automated maritime navigation systems.").
Although a lot of work has been put into it, be aware that the software is still in a proof-of-concept stage and you may find currently unused code that was once used to explore alternative solutions, undocumented parts, missing comments, and other imperfections.
