As systems become more complex and supply chains more intricate, simulation becomes indispensable to avoid integration problems. In the context of an exchange between OEM and supplier, effective communication between OEMs and suppliers is crucial to ensure accurate and reliable simulation models. However, current practices often rely on informal exchanges—through emails, meetings, or unstructured documents—which can lead to misunderstandings, incomplete specifications, and errors in model integration. These issues are further amplified by the difficulty of maintaining traceability across the model lifecycle, the lack of formalized processes for verification and validation (V&V), and the challenge of assessing model fidelity when simulations are shared as black boxes.
