A dynamic requirement tracking and change impact analysis method based on a meta-model framework

Abstract

The application belongs to the technical field of system engineering full life cycle requirement management, more particularly to a dynamic requirement tracking and change influence analysis method based on a meta-model framework, a four-layer meta-model framework composed of a structure layer, a meta-attribute layer, a relationship layer and a logic algorithm layer is built, and meta-model building, algorithm configuration and change influence analysis are completed in turn; relying on the structure layer algorithm, standardization elements are obtained by splitting engineering information, multi-dimensional attributes of the elements are automatically annotated by attribute algorithms, and internal, tracking and verification three types of association relationships between the elements are automatically constructed by means of a dynamic association relationship algorithm; after the change is triggered, the influence propagation analysis algorithm is used to traverse along the association link, automatically locate all affected elements and output an analysis report, overcoming the defects of traditional RTM static lag, single dimension and change analysis relying on artificial experience, realizing dynamic and automatic tracking and intelligent research and judgment of change influence of complex system full life cycle requirements, and improving requirement management efficiency and analysis accuracy.
