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.

Process concepts

This section will follow the same structure as Chapter 4, Life Cycles, by introducing and discussing Process concepts and developing an Ontology that will form part of a broader MBSE Ontology.

The first few concepts that must be understood are shown in the following figure:

Figure 5.1: An Ontology Definition View for Process concepts

The diagram in Figure 5.1 shows the initial Ontology Definition View for Process concepts, visualized using a SysML block definition diagram.

The main concept in this View is the Process, which describes an approach to doing something or achieving an aim of some description. As can be seen in the preceding figure, the Process is made up of three main elements:

  • Activities: An Activity describes a behavioral step that must be performed in order to execute the Process. A typical Process will be made up of a number of these Activities, each of which will have inputs, which are consumed, and outputs, which are...
