DEVS Unified Process for Web-Centric Development and Testing of System of Systems
Abstract
A critical aspect and differentiator of a System of Systems (SoS) versus a single monolithic system is interoperability among the constituent disparate systems. A major application of Modeling and Simulation (M&S) to SoS Engineering is to facilitate system integration in a manner that helps to cope with such interoperability problems. A case in point is the integration infrastructure offered by the DoD Global Information Grid (GIG) and its Service Oriented Architecture (SOA). In this paper, we discuss a process called DEVS Unified Process (DUNIP) that uses the Discrete Event System Specification (DEVS) formalism as a basis for integrated system engineering and testing called the Bifurcated Model-Continuity lifecycle development methodology. DUNIP uses an XML-based DEVS Modeling Language (DEVSML) framework that provides the capability to compose models that may be expressed in a variety of DEVS implementation languages. The models are deployable for remote and distributed real-time executing agents over the Service Oriented Architecture (SOA) middleware. We also compare DUNIP with the Model Driven Architecture (MDA) paradigm and provide overview of various projects that led to the formulation of DUNIP.
