Study Notes

This text discusses the use of a general-purpose modeling language in Systems Engineering (SE) for Modeling and Simulation (MA&S) purposes.
A PDF copy of the SE Handbook is provided for personal use only and should not be distributed publicly.
A methodology is necessary for SE practitioners to align their approach to MA&S throughout a system's life cycle.
Tools for MA&S include software applications, HPC facilities, and general-purpose digital computers.
MA&S quality is critical and should align with the SE processes described in the handbook.
Digital models offer various computational benefits, enabling modeling metrics like compliance and coverage.
Adoption of MA&S is driven by the increasing software-intensiveness of complex systems.
SE MA&S must interoperate with other engineering disciplines through an integrated system model repository.
MA&S tools consist of user interfaces, construct palettes, model editors, and various views for visualization and reporting.
Verification, Validation, and Accreditation (VV&A) are essential for ensuring MA&S quality and credibility.
Industrial practice emphasizes MA&S's economical and scalable benefits for analyzing and simulating complex systems.
