MODEL DRIVEN VEHICLE SYSTEM ENGINEERING: REQUIREMENTS, ISSUES AND CHALLENGES

摘要

The requirements, issues and challenges of establishing a model-driven vehicle system engineering (MD-VSE) process are explored. The needs for new methodologies, processes and infrastructure to address complex system level design issues are highlighted. The problem is viewed from the perspective of the relation between vehicle engineering domains and vehicle attribute and function requirements. With this view, an incremental approach to establishing a MD-VSE process is outlined. The approach consists of developing modeling frameworks to address critical attribute and function trade-off scenarios. The modeling frameworks would allow more formal and up front optimization and sensitivity analysis than is currently realized. In order to sustain these frameworks, a modeling cascade process has also been outlined. This would place formal requirements on VED's to deliver models to support the MD-VSE process.
