UML 2 Activity Model Support for Systems Engineering Functional Flow Diagrams

Published

Author(s)

Conrad E. Bock

Abstract

This article compares Activity models of the Unified Modeling Language, version 2 (UML 2) [U2 Partners 2003], to a popular systems engineering (SE) flow diagram, the Enhanced Functional Flow Block Diagram (EFFBD) [Long 2002], and to the requirements for a systems engineering extension for UML (UML-SE) [SE-DSIG 2003a]. Issues are identified in applying UML 2 Activities to EFFBD and to satisfying UML-SE requirements. Solutions are suggested to these issues that can be used to translate between the languages and to develop standards such as revisions to UML 2 or extensions in UML-SE.
