As systems become increasingly complex since they combine mechanical, electrical, computational, as well as human-centric components Model-Based Systems Engineering (MBSE) has emerged as indeed a key approach for the managing of their lifecycle. Since this complexity exists, the use of Multi-Model Modeling (MPM) is required so different parts of a system are modeled at varying levels of abstraction and with different formalisms. Orchestrating and maintaining these many heterogeneous models falls within the Model Management (MoM) discipline.

This challenge was inspired by the Royal Belgian Institute for Space Aeronomy (BIRA-IASB) visit for a satellite configuration case study. It is addressing key model management issues that exist in complex cyber-physical systems since it uses diverse artefacts that include designs, requirements, analyses, and also reports commonly represented in different formats and modeling languages. A public GitHub repository has these available artefacts. They seek to show how one can maintain consistency, traceability, and synchronization between heterogeneous models.

Model Management Scenarios

The MoM Challenge 2025 has as its focus Satellite Configuration Scenarios. This challenge will take place during 2025. It starts with a change in a thruster’s mass component, also this change impacts multiple linked artefacts. System requirements must be validated with architecture specifications updated by participants. Checking the satellite is a key task. It still must be meeting of the mass limit constraint. Models for views are used by engineers and the full architecture model must propagate changes in the views. Artefact versioning as well as catalogue versioning must be tracked by you. Report versioning includes this also. Participants handle live and also offline collaborative modeling scenarios. Strategies for conflict reconciliation and detection are evaluated. The challenge addresses core MoM issues: consistency, traceability, versioning, views, and collaboration.
