1. Introduction to DODAF, MODAF and UAF

The most common system reference architectures in the military field are:

DODAF is the earliest military domain reference framework and the reference foundation for other architectural frameworks, DODAF provides eight perspectives on architecture, as follows:

OMG provides the Architecture Modeling Specification UPDM for DODAF based on UML and Sys ML, providing a common modeling language for architecture modeling.

UAF has also established a corresponding UAF modeling language on the basis of UPDM.

2. Introduction to the Modeling Tool EA

The modeling tool EA is currently the most popular tool, which has been widely used in the fields of automotive electronics, aerospace, shipbuilding, rail transit, enterprise informatization, system engineering, and software engineering, and has accumulated a large number of users and cases.

The modeling tool EA also provides modeling support for DODAF and MODAF, including support for the corresponding modeling language UPDM, and provides corresponding modeling wizards and model legends.

The modeling tool EA also provides modeling support for UAF, including support for the corresponding modeling language UAFML and provide the corresponding modeling wizard and model legend.

The following is a brief introduction to the modeling support provided by the modeling tool EA for DODAF, MODAF, UAF.

6. Introduction to the Architecture Engineering (DODAF, MODAF, UAF) toolchain

In order to effectively support the architecture engineering of DODAF, MODAF and UAF, it is necessary to establish a complete set of engineering environment around the model, so that the model can support specific work and realize the continuous accumulation and development of the architecture. To this end, we offer a complete DODAF, MODAF and UAF toolchain, with a brief table of contents as follows:

Here's a brief overview of the system simulations, process guides, and model libraries that are part of it.

6.1 Model simulation of multi-system cooperation

After establishing the architecture based on DODAF, the system needs to be simulated and verified, and the multi-system simulator provides system-level simulation capabilities, which can simulate the cooperation of multiple systems to complete operations and realize capabilities. Based on simulation, the correctness and completeness of the architecture can be verified.

6.2 Modeling Guide: iSpace

DODA F, MODAF, UAF modeling is a complex and long-term process, so the current specification also regards the architecture development process as part of MBSE, and it is necessary to provide corresponding process guidance models, and track and manage processes, deliverables, and roles. The MBSE platform iSpace provides the following process support for DODAF and UAF:

•  Guidance on the architecture design process

•  Relevant roles and responsibilities

•  Various models, documents, and tracking relationships delivered

The following is a screenshot of the process guide interface of iSpace's DODAF:

Here's a screenshot of the artifact model for iSpace's DODAF:

6.3 Model Library: ModelCenter

Complex architecture engineering is not something that can be successfully achieved by a few people in a short period of time, but requires team cooperation and long-term accumulation, and the continuous construction of corresponding specifications, which requires a model library that can support complex architecture. To this end, we provide a library of multidimensional models that can be stored and provide convenient online management.

DODAF, MODAF, UAF models can be established in the multi-dimensional engineering model library, and the association of multiple models can be realized. Managers can review the model and then publish it, using the architecture model as a resource for business analysis, system construction, and personnel development. This is the key to realizing the value of DODAF, MODAF, UAF models.

6.4 Model Publishing: WebEA

Models can be published through WebEA, so that everyone can browse the model, use the model, and provide feedback mechanism to the model through the web page, so that the model can become a reference and basis for daily work.。
