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.

Module: Models - Group: Examples

This repository contains some example models for all levels of the multi-level modelling hierarchy.
To be precise the sub-modules o2-topic and o1-domain are model related. The sub-module o0-testcase on the other hand contains the library in line with the novel concept that is the basis of DisCo-BaTS.

Important

This framework was developed as part of a doctoral thesis successfully defended on April 30, 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.") [FULLTEXT]. 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.
