Description

This two-day short course, based on segments of three semester-long graduate-level systems engineering courses, provides an overview the Digital Engineering (DE) of systems, and how models, simulations, and data enable its implementation.  The course begins with an introduction focusing on the U.S. Department of Defense (DoD) DE Strategy, key competencies for DE, and key Modeling and Simulation (M&S) terms and processes.  The course then presents an overview of the types of models and simulations that are used across the phases of the Systems Engineering life cycle, from system needs analysis through system sustainment.  Examples are given for several types of systems, including systems developed under the U.S. DoD acquisition process.

The course then provides information on several M&S topics, including Model Based Systems Engineering, along with the Systems Modeling Language; simulation interoperability standards, architectures, and techniques; and modeling of the natural and man-made environments.  The course culminates by putting the aforementioned topics together in an architecture for a collaborative environment to support DE that includes models, simulations, data, processes, and standards, including a repository to implement what the U.S. DoD DE Strategy calls the Authoritative Source of Truth.  Finally, the course explains how the collaborative environment can be applied to implement Digital Threads and Digital Twins.

What You Will Learn:

  • Name the five strategic goals of the U.S. Department of Defense Digital Engineering initiative
  • Define and distinguish key Modeling and Simulation (M&S) terms
  • Describe how M&S tools are used in each phase of the Systems Engineering process
  • Explain Unified Modeling Language (UML) and Systems Modeling Language (SysML) diagrams
  • Describe the use of simulation interoperability standards and Live-Virtual-Constructive (LVC) simulation techniques
  • Compare and contrast modeling of the natural and man-made environment
  • Construct a top-level architectural view of a collaborative environment for Digital Engineering

Who Should Attend:

This short course is intended for systems engineers who are seeking a broad understanding of Digital Engineering of systems, and how models, simulations, and data enable its implementation.  A basic knowledge of the systems engineering process is helpful, but detailed knowledge of models and simulation is not necessary, as the short course will explain how models and simulations are used across all phases of the systems engineering process.  The short course is not intended to provide a “deep dive” into any specific modeling or simulation language, but will provide for a basic understanding of diagrams used in the Unified Modeling Language and the Systems Modeling Language.  As an adjunct to the presentation slides, an extensive list of references will be provided, so that participants can access resources to obtain more detailed information on the topics presented.
