1.Introduction to MBSE

MBSE (Model-Based Systems Engineering) is an effective method for analyzing, designing, and developing complex systems. At present, the scale of aviation, automobile, machinery, shipbuilding, and enterprise informatization systems is getting larger and larger, and more and more specialties are involved, which makes the construction of the system face unprecedented challenges:

The following is the MBSE Process Framework V model:

2.The working process of MBSE

MBSE (Model-Driven Systems Engineering) involves the entire system development cycle, and the overall workflow of MBSE is as follows:

The activities performed by the various roles are:

3.MBSE related workpieces

Various models are used throughout the MBSE lifecycle, the main ones are as follows:

These models involve different modeling criteria, such as:

4.Use EA for full-cycle modeling of MBSE:

MBSE modeling involves multiple levels: business, system, software, algorithm, physical system, and the modeling tool EA provides standard support for MBSE full-cycle modeling: business modeling, SysML, UML, MARTE, etc., as shown in the following figure:

The modeling tool EA also provides full model-based engineering practice support, with the following supported features:

This enables model-based requirements analysis, design, and simulation validation.

Here's a view of EA's workflow for MBSE support.

EA's specific support for MBSE is as follows:

5. Use iSpace for MBSE process management

MBSE involves multiple levels of work:

This inevitably involves a variety of roles, a variety of jobs, a variety of models, a variety of documents, and a variety of tools, which requires a platform that supports the full cycle of MBSE, and iSpace is such a platform.

iSpace is positioned to allow engineers to model the process of the MBSE itself, so that the various roles involved can understand their workflows, artifacts, and tools, and then establish a foundation for collaboration. iSpace can be right MBSE Process Modeling:

iSpace supports the complete project management of MBSE, including the following aspects:

• 1.MBSE Process Guide
• 2. Support the model library and team collaboration of the whole cycle of MBSE
• 3. Model-based 3D R&D management
• 4. Integrate various engineering tools with MBSE
• 5. Model-based project management
• 6. Model-based requirements management
• 7. Design modeling, simulation and management
• 8. Model-based test management
• 9. Model-based quality management
• 10. Model-based tracking management
• 11. Engineering Data Object Management

iSpace can help you solve the following problems:

The following figure shows the functional structure of iSpace

The following is a summary of the functions of iSpace:

Below, we'll take a closer look at each of the features of iSpace

6 MBSE Process Modeling

MBSE is a full-cycle system development process, involving multiple stages, multiple roles, multiple activities and artifacts, the roadmap of the entire process, the collaboration of roles, and the tracking and management of artifacts are all relatively complex things, so MBSE itself also needs to be modeled, iSpace provides three-dimensional modeling of MBSE, including: workflow, role model, and workpiece model. You can associate individual views: the activities of the workflow are associated with the responsibilities of the role, the instances of the artifacts. This allows engineers to have a clear and complete understanding of MBSE from three perspectives.

In iSpace, users can collaborate and manage various models built by EA as a team, including:

6.1 Process View

The following is the MBSE process modeling, which shows the MBSE process in the form of a flow chart:

6.2 Role View

The following is the MBSE role modeling, which is described as follows:

6.3 Workpiece View

The following is the MBSE artifact modeling, which is described as follows:

7. 3D R&D management

Support model-centered 3D R&D management, can provide 3D views: items, models, documents, users can choose the corresponding view according to their own needs to work:

After the model diagram is converted into an itemized list view, the full cycle of tracking can be realized: requirements, > design, > development, > testing, and users can create corresponding tracking views according to their needs:

Two tracking modes are supported: Trace Tree and Trace Table:

Model-based 3D R&D management includes:

The details below are as follows:

7.1 Model-Based Requirements Management (with iSpace)

You can browse the requirements model in an itemized view for requirements management:

7.2 Model-Based Design Management (using iSpace)

You can browse the design model in an itemized view for design management:

The following is the design model and the tracking relationship between them, which can be established in the form of a list in iSpace.

7.3 Model-Based Design Management (Using iSpace)

Modeling tests that can be combined with EAs, including: modeling tests based on graphics;

You can browse the test model in an itemized view for test management:

7.4 Quality management (model-based)

iSpace provides quality index modeling and measurement functions, which can help users establish a complete quality evaluation system for the whole cycle of MBSE:

In MBSE (Model-Based Systems Engineering), the emphasis is on taking the model as the deliverable of requirements and design work, and the model-based evaluation of requirements and design quality can be more accurate, which can effectively improve the quality of requirements and design work, and thus improve the quality of the whole system. This requires us to map the traditional requirements and design quality evaluation indicators to the corresponding requirements and design models, transform them into practical requirements models and design model evaluation indicators, and establish corresponding evaluation methods and guidelines. This work should be team size and continuous, which requires tools to make quality assessments simple and easy to accumulate.

Model-based quality review with iSpace supports the following features:
