Motivation for Modeling Standards
Modeling standards play an important role in defining agreed-upon system modeling concepts that can be represented for a particular domain of interest, and they enable integration of different types of models across domains of interest. Modeling standards are extremely important to support MBSE, which must integrate across disciplines, products, and technologies.
Standards for system modeling languages also can enable cross-discipline, cross-project, and cross-organization communication. This communication offers the potential to reduce training requirements for practitioners who need to learn about a particular system, and enables the reuse of system artifacts. Standard modeling languages also provide a common foundation for advancing the practice of systems engineering as do other systems engineering standards.
Types of Modeling Standards
Many different standards apply to systems modeling. Modeling standards include standards for modeling languages, data exchange between models, and for transformation of one model to another to achieve semantic interoperability, as well as more general modeling standards. Each type of model can be used to represent different aspects of a system, such as representing the set of system components and their interconnections and interfaces, or representing a system to support performance analysis or reliability analysis.
Following is a partial list of representative modeling standards, including a common acronym for many and a reference where more information can be found.
