The innovative process of electric multiple units(EMU)design necessitates a comprehensive consideration of various factors,including the adaptation to diverse operational scenarios such as high-speed travel and ground mobility.This design process involves analyzing factors such as operating environments,conditions,overhead catenary systems and signal transmission,and to construct a system-level framework for structural modeling based on the on the capability of EMU.Drawing from the framework of the united states department of defense architecture framework(DoDAF),and employing methods of scenario modeling and requirements capture,combined with a customized view description language UPDM tailored to the DoDAF modeling framework,results in an architecture-based design idea.Enhanced structural design through enhancements to the UPDM language such as block diagrams and activity diagrams.In this paper,we take the"departure scenario"of EMU as an example,describe its operation process comprehensively,and integrate requirements analysis,functional decomposition and system integration to construct a system engineering development methodology with behavior-driven functions as the core.
