Systems engineering

Interdisciplinary field of engineering

For other uses, see Systems engineering (disambiguation).

Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their life cycles. At its core, systems engineering utilizes systems thinking principles to organize this body of knowledge. The individual outcome of such efforts, an engineered system, can be defined as a combination of components that work in synergy to collectively perform a useful function.

Issues such as requirements engineering, reliability, logistics, coordination of different teams, testing and evaluation, maintainability, and many other disciplines, aka "ilities", necessary for successful system design, development, implementation, and ultimate decommission become more difficult when dealing with large or complex projects. Systems engineering deals with work processes, optimization methods, and risk management tools in such projects. It overlaps technical and human-centered discip

Systems Engineering STEM Overview

Lead Author:Bill Schindel

Engineering disciplines (ME, EE, CE, ChE) sometimes argue their fields have “real physical phenomena”, “hard science” based laws, and first principles, claiming Systems Engineering lacks equivalent phenomenological foundation. Here we argue the opposite, and how replanting systems engineering in MBSE/PBSE supports emergence of new hard sciences and phenomena-based domain disciplines with deep historical roots. Supporting this perspective is the System Phenomenon, wellspring of engineering opportunities and challenges. Governed by Hamilton’s Principle, it is a traditional path for derivation of equations of motion or physical laws of so-called “fundamental” physical phenomena of mechanics, electromagnetics, chemistry, and thermodynamics.

We argue that laws and phenomena of traditional disciplines are less fundamental than the System Phenomenon from which they spring—an historical fact that was well-known and equally remarkable 200 years earlier to the pioneers of mathematical physics. This is a practical remind

A Brief History of Systems Engineering

Lead Author:Robert Cloutier; Contributing Author:Michael Pennotti

While many will attribute systems thinking to great accomplishments such as the Egyptian pyramids, Incan ziggurats, and the Roman aqueduct system, this article will pick up with the early mentions of systems engineering as a discipline. One only has to look to find a healthy body of works on the history of systems engineeringsystems engineering. Many of those articles are cited in the References section below. The purpose of this article is to highlight the evolution of both the practice and definition of systems engineering as it emerged in the 20th century.

The Forties and Fifties (1940-1959)

During World War II, systems engineering began to emerge to deal with the myriad new technologies developed in support of the war effort. For example, an analysis of the RAF Fighter Command C2 System, which was crucial to the United Kingdom’s prevailing in the 1940 Battle of Britain, performed by Derek Hitchens in 2005, concluded that its design represented “systems en
