GB/T 43270-2023 in English

1. Background and significance of the standard

GB/T 43270—2023 "X language architecture for integrated modeling language for collaborative design of complex products" is a standardized document developed to meet the challenges of collaborative design of modern complex products. The standard aims to unify the model description and simulation process in the development of complex products to ensure efficient collaboration between different fields and teams.

2. X language architecture

The X language combines multiple modeling methodologies (such as DEVS specification and Modelica semantic syntax), revises and expands SysML elements, and forms an object-oriented modeling language that supports MBSE. Its hierarchical structure is clear and can achieve integrated modeling and simulation of the system.

3. Analysis of standard key terms

The key terms in the X language system include:

• Basic class: supports generalization into specific classes to describe different types of models.
• Restricted class: a general term for classes that inherit some functions from the basic class, such as continuous class, discrete class, etc.
• Couple class: describes the coupling relationship between multi-domain, multi-feature, and multi-level system models.

4. Standard Syntax Structure

The syntax structure of X language mainly consists of classes, graphical modeling and related parts, as shown in the table:

5. Graphical modeling method

The graphical modeling of X language is based on SysML, including definition diagram, connection diagram, equation diagram, etc., as shown in the table:

6. Implementation suggestions

To ensure the effective application of X language, it is recommended to:

1. Carry out detailed requirements analysis and modeling training at the beginning of the project.
2. Choose appropriate modeling tools and integrate them into the existing development process.
3. Pay attention to model verification and application feedback of simulation results.
