Ehdotuksen tiedot

The purpose of this standard is to specify the Systems Modeling Language™ (SysML), to guide the implementation of conformant modeling tools, and to provide the basis for the development of material and other resources to train users in the application of SysML.

 

SysML is a general-purpose modeling language for modeling systems that is intended to facilitate a model-based systems engineering (MBSE) approach to engineer systems. It provides the capability to create and visualize models that represent many different aspects of a system. This includes representing the requirements, structure, and behavior of the system, and the specification of analysis cases and verification cases used to analyze and verify the system. The language is intended to support multiple systems engineering methods and practices. The specific methods and practices may impose additional constraints on how the language is used.

 

SysML is defined as an extension of the Kernel Modeling Language (KerML), which provides a common, domain independent language for building semantically rich and interoperable modeling languages. SysML also provides a capability to provide further language extensions. It is anticipated that SysML will be customized using this language extension mechanism to model more specialized domain-specific applications, such as automotive, aerospace, healthcare, and information systems, as well as discipline specific extensions such as safety and reliability.
