The invention discloses a SysMLv2.0 model
library multiplexing method based on definition driving. The method comprises the following steps: S1, constructing a model definition
library containing structures, behaviors, interfaces, constraints and semantic attributes; s2, analyzing a modeling demand, identifying a to-be-multiplexed module, and determining a definition unit identifier; s3, calling the target definition unit and inserting the target definition unit into the current model in a reference mode; s4, performing context
adaptation to generate a binding relationship; s5, setting a version identification mechanism, and establishing a version mapping index between the use unit and the definition unit; s6, registering a reference relationship and an
adaptation rule, and generating a modeling
metadata document; s7, automatically updating the content of the use unit according to the
metadata document in the modeling process; and S8, executing consistency
verification after use unit integration is completed, and ensuring correct interface connection, conflict-free constraint logic and complete version binding. According to the method, a definition-driven
model system is constructed, and cross-context semantic
multiplexing and version consistency modeling management are realized.
