Model Based System Engineering

Chapter 9Conclusion

In this book, we have looked into the basic concepts and real-world uses of model-based systems engineering (MBSE). We started with an overview of the key concepts and principles behind this important way of practicing systems engineering. We also looked at the history that led to MBSE, the problems created by the increasing complexity of modern systems, and the drawbacks of older document-based approaches.

As we progressed further into MBSE, we unpacked the complex ideas and practices that are fundamental to the field. We discussed how systems, languages, and models are interconnected and reviewed the various types of models used in MBSE, including structural and behavioral models, as well as hybrid and agent-based models. We highlighted the advantages of using formal languages and the importance of managing interfaces and viewpoints in designing complex systems.

We devoted a significant amount of time to the important processes of model verification and validation (V&V). We examined the theories and practical methods that ensure system models are correct, consistent, and complete. The evolution of V&V practices, the key issues they address, and the standards and best practices guiding their use were thoroughly covered. We also stressed the essential role of V&V in limiting design space exploration and reducing costs and delays in system design and development.

The principles of system architecting and the concepts of MBSE were important in our study. We ...
