Get to grips with systems engineering life cycles, processes, and best practices to discover techniques that will help you successfully develop complex systems
Key Features
Discover how to manage increased complexity and understand systems via effective communication
Adopt a model-based approach for systems engineering and learn about the art of modeling
Apply up-to-date techniques for design, deployment, validation, verification, and systems engineering management
Book Description
Written by an internationally recognized systems engineering expert, this book provides a blend of technical and business aspects you need to understand to develop successful systems.
This edition outlines the most up-to-date approaches to MBSE, alongside two new chapters on deploying MBSE. You'll start by tackling the complexity, communication, and different stakeholders' views of the system. Next, you'll cover essential aspects of model-based systems engineering, systems, life cycles, and processes, along with techniques to develop systems. You'll also explore system models and visualization techniques, focusing on the SysML, and discover how solutions can be defined by developing effective system design, verification, and validation techniques. Towards the end, you'll explore key management processes and systems engineering best practices and guidelines.
Fully updated and expanded, this book now covers how to deploy MBSE successfully within an organization using the Trinity approach. There is also a whole new section on the author’s philosophy and approach to modeling based on his 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.
What you will learn
Understand the three evils of systems engineering - complexity, ambiguous communication, and lack of understanding
Realize successful systems using model-based systems engineering
Understand the concept of life cycles and how they control the evolution of a system
Explore processes and related concepts such as activities, stakeholders, and resources
Discover how needs fit into the systems life cycle and which processes are relevant and how to comply with them
Find out how design, verification, and validation fit into the life cycle and processes
Learn how to deploy MBSE using the Trinity approach
Gain a deeper understanding of how to model in an effective and efficient manner
Who This Book Is For
This book is for aspiring systems engineers, engineering managers, or anyone looking to apply systems engineering practices to their systems and projects. While a well-structured, model-based approach to systems engineering is an essential skill for engineers of all disciplines, many companies are finding that new graduates have little understanding of MBSE. This book supports you to acquire this skill with the help of a simple and practical approach to developing successful systems. No prior knowledge of systems engineering or modeling is required to get started with this book.
