Industrial engineering
Industrial engineering (IE) is concerned with the design, improvement and installation of integrated systems of people, materials, information, equipment and energy. It draws upon specialized knowledge and skill in the mathematical, physical, and social sciences together with the principles and methods of engineering analysis and design, to specify, predict, and evaluate the results to be obtained from such systems. Industrial engineering is a branch of engineering that focuses on optimizing complex processes, systems, and organizations by improving efficiency, productivity, and quality. It combines principles from engineering, mathematics, and business to design, analyze, and manage systems that involve people, materials, information, equipment, and energy. Industrial engineers aim to reduce waste, streamline operations, and enhance overall performance across various industries, including manufacturing, healthcare, logistics, and service sectors.
Industrial engineers are employed in numerous industries, such as automobile manufacturing, aerospace, healthcare, forestry, finance, leisure, and education. Industrial engineering combines the physical and social sciences together with engineering principles to improve processes and systems.
Several industrial engineering principles are followed to ensure the effective flow of systems, processes, and operations. Industrial engineers work to improve quality and productivity while simultaneously cutting waste. They use principles such as lean manufacturing, six sigma, information systems, process capability, and more.
These principles allow the creation of new systems, processes or situations for the useful coordination of labor, materials and machines. Depending on the subspecialties involved, industrial engineering may also overlap with, operations research, systems engineering, manufacturing engineering, production engineering, supply chain engineering, process engineering, management science, engineering management, ergonomics or human factors engineering, safety engineering, logistics engineering, quality engineering or other related capabilities or fields.
The origins of industrial engineering are generally traced back to the Industrial Revolution with the rise of factory systems and mass production. The fundamental concepts began to emerge through ideas like Adam Smith's division of labor and the implementation of interchangeable parts by Eli Whitney. The term "industrial engineer" is credited to James Gunn who proposed the need for such an engineer focused on production and cost analysis in 1901. However, Frederick Taylor is widely credited as the "father of industrial engineering" for his focus on scientific management, emphasizing time studies and standardized work methods, with his principles being published in 1911. Notably, Taylor established the first department dedicated to industrial engineering work, called "Elementary Rate Fixing," in 1885 with the goal of process improvement and productivity increase. Frank and Lillian Gilbreth further contributed significantly with their development of motion studies and therbligs for analyzing manual labor in the early 20th century. The early focus of the field was heavily on improving efficiency and productivity within manufacturing environments, driven in part by the call for cost reduction by engineering professionals, as highlighted by the first president of ASME in 1880. The formalization of the discipline continued with the founding of the American Institute of Industrial Engineering (AIIE) in 1948. In more recent years, industrial engineering has expanded beyond manufacturing to include areas like healthcare, project management, and supply chain optimization.
The origins of systems engineering as a recognized discipline can be traced back to World War II, where its principles began to emerge to manage the complexities of new war technologies. Although systems thinking predates this period, the analysis of the RAF Fighter Command C2 System during the Battle of Britain (even though the term wasn't yet invented) is considered an early example of high-caliber systems engineering. The first known public use of the term "systems engineering" occurred in March 1950 by Mervin J. Kelly of Bell Telephone Laboratories, who described it as crucial for defining new systems and guiding the application of research in creating new services. The first published paper specifically on the subject appeared in 1956 by Kenneth Schlager, who noted the growing importance of systems engineering due to increasing technological complexity and the formation of dedicated systems engineering groups. In 1957, E.W. Engstrom further elaborated on the concept, emphasizing the determination of objectives and the thorough consideration of all influencing factors as requirements for successful systems engineering. That same year also saw the publication of the first textbook on the subject, "Systems Engineering: An Introduction to the Design of Large-Scale Systems" by Goode and Mahol. Early practices of systems engineering were generally informal, transdisciplinary, and deeply rooted in the application domain. Following these initial mentions and publications, the field saw further development in the 1960s and 1970s, with figures like Arthur Hall defining traits of a systems engineer and viewing it as a comprehensive process. Despite its informal nature, systems engineering played a vital role in major achievements like the 1969 Apollo moon landing. A significant step towards formalization occurred in July 1969 with the introduction of the first formal systems engineering process, Military Standard (MIL-STD)-499: System Engineering Management, by the U.S. Air Force. This standard aimed to provide guidance for managing the systems engineering process and was later extended and updated. The need for formally trained systems engineers led to the formation of the National Council on Systems Engineering (NCOSE) in the late 1980s, which evolved into the International Council on Systems Engineering (INCOSE). INCOSE further contributed to the formalization of the field through publications like its journal "Systems Engineering" starting in 1994 and the first edition of the "Systems Engineering Handbook" in 1997. Additionally, organizations like NASA published their own systems engineering handbooks. In the 21st century, international standardization became a key aspect, with the International Standards Organization (ISO) publishing its first standard defining systems engineering application and management in 2005, further solidifying its standing as a formal discipline.
Frederick Taylor (1856–1915) is generally credited as the father of the industrial engineering discipline. He earned a degree in mechanical engineering from Stevens Institute of Technology and earned several patents from his inventions. Taylor is the author of many well-known works, including a book, The Principles of Scientific Management, which became a classic of management literature. It is considered one of the most influential management books of the 20th century. The book laid our three goals: to illustrate how the country loses through inefficiency, to show that the solution to inefficiency is systematic management, and to show that the best management rests on defined laws, rules, and principles that can be applied to all kinds of human activity. Taylor is remembered for developing the stopwatch time study. Taylor's findings set the foundation for industrial engineering.
Frank Gilbreth (1868-1924), along with his wife Lillian Gilbreth (1878-1972), also had a significant influence on the development of Industrial Engineering. Their work is housed at Purdue University. In 1907, Frank Gilbreth met Frederick Taylor, and he learned tremendously from Taylor's work. Frank and Lillian created 18 kinds of elemental motions that make up a set of fundamental motions required for a worker to perform a manual operation or task. They named the elements therbligs, which are used in the study of motion in the workplace. These developments were the beginning of a much broader field known as human factors or ergonomics.
