International Classification:

G06F 9/45

US Classification:

717132

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.

Abstract:

A system and method for ontology-enhanced traceability in design and management applications employ ontology nodes embedded in a processor executable traceability link (network) coupling processor executable requirement modules to processor executable engineering object modules to facilitate in all stages of engineering object development. The engineering object development occurs through multiple models of computation, control, and visualization platform networked together via ontology-enhanced traceability mechanism. Processor executable design rule checking module embedded in the design concept nodes creates a pathway for the development process validation and verification at early stages of the object lifecycle. Linking of ontologies/meta-models is performed for the purposes of supporting ontology-enabled traceability across multiple domains.
