Overview of this book

Systems engineering helps in developing and describing complex systems. Written by an internationally-recognized systems engineering expert, this updated edition provides insight into elements to consider when designing a complex system that is robust and successful. The latest edition covers the new approaches of Model-Based Systems Engineering (MBSE) and its deployment techniques using the Trinity approach. You will learn about the system engineering life cycle and processes to implement. Effective systems can be built only when the system is designed with close attention to detail, meaning each aspect of the system is recognized and understood before the system is built. The book explains in great detail, different system models and visualization techniques, with a focus on SysML, to help you visualize a system in the design phase. You will also learn various verification and validation techniques to ensure your system design is ready to be implemented. The book ends with key management processes, systems engineering best practices, and guidelines, with a new section on effective approaches based on the author’s impressive 30 years of experience in the field. By the end of this systems engineering book, you'll be able to apply modern model-based systems engineering techniques to your own systems and projects.

The Model versus Modeling

When we initially start to think about MBSE, it is important that we understand exactly what we mean by the term. Obviously, the key to this is the word Model. Just the term Model is fraught with ambiguity as different people will have different definitions of exactly what they mean by that term, which we can clarify by effective use of an Ontology.

A common misunderstanding, however, that often arises comes from the fact that the word Model can be both a noun and a verb, which leads us to two main discussion points, which are related to each other.

Firstly, consider the word Model when used as a noun; so, we may be referring to “a Model” or “the Model.” When we use the word as a noun, we are really talking about a simplified representation of something, or an abstraction.

Therefore, it could be a mathematical model, a graphical model, a text statement, etc. Another aspect of the term Model when used as a noun is that...
