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: Editor - Group: Tools

⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️
This GUI desktop editor app was developed during an earlier development iteration and IS CURRENTLY NOT WORKING with the current latest meta-model implementation.
However since adapting the editor code to the latest meta-model structures should be quite easy, the complete code base was published nevertheless. It probably will be fixed / adapted at some point in time, but feel free to help doing so. 🔧

Possible TODOs

• Console outputs for the following events
  • Attribute type has been changed
  • Default value of attribute has been changed
• Possible exceptions that could occur
• Not all properties are selectable for communication objects
• Hide dropdown if empty
• Different zoom levels for the EditorPane
• Always display attributes in the same order
• Rename elements that have already been created

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.
