Model-Based Systems Engineering (MBSE) employs model-based technologies and established systems engineering practices. Model-Driven Engineering (MDE) provides various concepts to automate model based practices using metamodeling. We describe the DEVS Unified Process (DUNIP) that aims to bring together MBSE and MDE as Model-driven Systems Engineering (MDSE) and apply it in a netcentric environment. We historically look at various model-based and model-driven flavors and suggest MDSE/DUNIP as one of the derived methodologies. We describe essential elements in DUNIP that facilitate integration with architecture solutions like Service Oriented Architecture (SOA), Event Driven Architectures (EDA), Systems Entity Structures (SES) ontology, and frameworks like Department of Defense Architecture Framework (DoDAF 2.0). We discuss systems requirement specifications, verification and validation, metamodeling, Domain Specific Languages (DSLs), and model transformation technologies as applicable in DUNIP. In this article, we discuss the features and contributions of DUNIP in netcentric system of systems engineering.
