Quantifying consistency of a system architecture by comparing analyses of property graph data models representing different versions of the system architecture

Abstract

A system and method generates two weighted property graph data models to represent a system architecture. The models each include a plurality of vertices representing a plurality of instances of a design dimension of the system architecture and a plurality of weighted compositional edges that connect first pairs of vertices to represent hierarchical directed-composition and hierarchical directed-decomposition of first pairs of instances of the design dimension represented by the corresponding connected first pairs of vertices with respect to one another, while only the first model includes a plurality of weighted interface edges that connect second pairs of the vertices to represent an information exchange interface between second pairs of instances of the design dimension represented by the corresponding connected second pairs of the vertices. Betweenness hierarchical clusters of each of the two models are generated and correlated with each other to quantify a consistency of the system architecture.
