• Ensure models meet appropriate fidelity levels depending on development phase (concept, design, integration, validation).
• Perform model validation and correlation against requirements and test data.
• Support model reduction and optimization for simulation efficiency.
• Model-Based Development Support
• Integrate plant models into XIL workflows and environments.
• Support virtual testing, requirement validation, and system verification activities.
• Collaborate with controls and system engineers to ensure alignment between plant models and control strategies.
• Contribute to continuous integration pipelines for model development and validation.
• Collaboration & Integration
• Work with:
• System and functional design teams
• Architecture and simulation framework teams
• Testing and validation teams
• Suppliers and tool vendors
• Ensure plant models:
• Are compatible with simulation platforms
• Support cross-domain integration
• Enable efficient data exchange and reuse
• Model Quality & Governance
• Follow established modeling best practices and standards
