System engineering is an interdisciplinary field of engineering and engineering management, which focuses on designing, integrating and managing complex systems over their life cycles. Fundamentally, it utilizes the principles of systems theory to organize this body of knowledge. An engineered system is the outcome of such efforts, a combination of components that collaborate to collectively perform a useful function. Systems engineering ensures that all likely aspects of a project or system are considered and integrated into a whole. It involves discovering real problems, identifying the most probable failures and finding solutions to these problems. This book elucidates the concepts and innovative models around prospective developments with respect to this field. There has been rapid progress in system engineering and its applications are finding their way across multiple industries. As this field is emerging at a rapid pace, the contents of this book will help the readers understand the modern concepts and applications of the subject.
