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.

Defining Life Cycle Models

Life Cycles are defined by identifying a set of Stages that describe the evolution of an Entity. A Life Cycle is a structural construct. A Life Cycle Model, on the other hand, is a behavioral construct that describes the execution of a Life Cycle, specifically the order of execution of the Stages.

In terms of visualizing the various Life Cycle Models, as the emphasis is on the order of the execution of the Stages that comprise the Life Cycle, a SysML sequence diagram will be used. This is good for the consistency of the overall Model but can lead to diagrams that differ in appearance compared to some of the traditional visualizations of Life Cycle Models. This is because most Life Cycle Models are visualized using non-standard, ad hoc notations, which leads to a set of very different-looking and difficult-to-compare diagrams. This illustrates one of the benefits of using a standard notation, such as SysML, as all of the different Life Cycle Models may...
