Tree-to-graph folding procedure for systems engineering requirements

Abstract

A method is provided for generating a graph data representation having a plurality of nodes corresponding to respective systems engineering requirements. The method includes accessing a first data representation of a collection of systems requirements and relationships therebetween and generating a second data representation of the collection of systems requirements. The generating the second data representation includes accessing respective systems requirements of the collection of systems requirements; creating a node to correspond to each accessed systems requirement if a node corresponding to the accessed systems requirement does not exist; and creating an edge between the created or pre-existing node and each node corresponding to a systems requirement having a relationship with the accessed systems requirement. Each node of the second data representation is a node of said graph data representation and corresponds to a different systems requirement of the collection of systems requirements.
