Industrial engineering

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Industrial engineering is a branch of engineering dealing with the optimization of complex

processes or systems. It is concerned with the development, improvement, implementation and evaluation of integrated systems of people, money, knowledge, information, equipment, energy, materials, analysis and synthesis, as well as the mathematical, physical and social sciences together with the principles and methods of engineering design to specify, predict, and evaluate the results to be obtained from such systems or processes. Its underlying concepts overlap considerably with certain business-oriented disciplines such as operations management, but the engineering side tends to emphasize extensive mathematical proficiency and usage of

quantitative methods.

Depending on the subspecialties involved, industrial engineering may also be known as, or overlap with, operations management, management science, operations research, systems engineering, manufacturing engineering, ergonomics or human factors engineering, safety

engineering, or others, depending on the viewpoint or motives of the user. For example, in health care, the engineers known as health management engineers or health systems engineers are, in essence, industrial engineers by another name.

] Overview

While the term originally applied to manufacturing, the use of "industrial" in "industrial engineering" can be somewhat misleading, since it has grown to encompass any methodical or quantitative approach to optimizing how a process, system, or organization operates. Some engineering universities and educational agencies around the world have changed the term

(2)

"industrial" to broader terms such as "production" or "systems", leading to the typical extensions noted above. In fact, the primary U.S. professional organization for Industrial Engineers, the Institute of Industrial Engineers (IIE) has been considering changing its name to something broader (such as the Institute of Industrial & Systems Engineers), although the latest vote among membership deemed this unnecessary for the time being.

The various topics concerning industrial engineers include management science, financial engineering, engineering management, supply chain management, process engineering, operations research, systems engineering, ergonomics / safety engineering, cost and value engineering, quality engineering, facilities planning, and the engineering design process.

Traditionally, a major aspect of industrial engineering was planning the layouts of factories and designing assembly lines and other manufacturing paradigms. And now, in so-called lean

manufacturing systems, industrial engineers work to eliminate wastes of time, money, materials, energy, and other resources.

Examples of where industrial engineering might be used include designing an assembly workstation, strategizing for various operational logistics, consulting as an efficiency expert, developing a new financial algorithm or loan system for a bank, streamlining operation and emergency room location or usage in a hospital, planning complex distribution schemes for materials or products (referred to as Supply Chain Management), and shortening lines (or queues) at a bank, hospital, or a theme park.

Industrial engineers typically use computer simulation (especially discrete event simulation), along with extensive mathematical tools and modeling and computational methods for system analysis, evaluation, and optimization.

] History

See also: List of industrial engineers

Efforts to apply science to the design of processes and of production systems were made by many people in the 18th and 19th centuries. They took some time to evolve and to be synthesized into disciplines that we would label with names such as industrial engineering, production

engineering, or systems engineering. For example, precursors to industrial engineering included some aspects of military science; the quest to develop manufacturing using interchangeable parts; the development of the armory system of manufacturing; the work of Henri Fayol and colleagues (which grew into a larger movement called Fayolism); and the work of Frederick Winslow Taylor and colleagues (which grew into a larger movement called scientific

management). In the late 19th century, such efforts began to inform consultancy and higher education. The idea of consulting with experts about process engineering naturally evolved into the idea of teaching the concepts as curriculum.

Industrial engineering courses were taught by multiple universities in Europe at the end of the 19th century, including in Germany, France, the United Kingdom, and Spain.[1] In the United States, the first department of industrial and manufacturing engineering was established in 1909

at the Pennsylvania State University. The first doctoral degree in industrial engineering was awarded in the 1930s by Cornell University.

engineering specialities in Industrial or Manufacturing. At the North Carolina State University[3] the Department head is Professor Paul Cohen. Also teaches in the Department Professor Rick Wysk who retired from the Penn State University,the first Industrial Engineering Department in the U.S.[4] The Georgia Institute of Technology has been ranked as having the best Industrial Engineering program in the United States consecutively for the last twenty-two years while the University of Michigan - Ann Arbor and University of California - Berkeley have been

consistently ranked second and third, respectively.

] Undergraduate curriculum

In the United States, the usual undergraduate degree earned is the Bachelor of Science or B.S. in Industrial Engineering (BSIE). Like most undergraduate engineering programs, the typical curriculum includes a broad math and science foundation spanning chemistry, physics, engineering design, system analysis and design, calculus, differential equations, statistics, materials science, engineering mechanics, computer science, circuits and electronics, and often additional specialized courses in areas such as management, systems theory, ergonomics/safety, stochastics, advanced mathematics and computation, politics, robotics and economics. Some Universities require International credits to complete the BS degree.[clarification needed]

] US Salaries and workforce statistics

The total number of engineers employed in the U.S. in 2006 was roughly 1.5 million. Of these, 201,000 were industrial engineers (13.3%), the third most popular engineering specialty. The average starting salaries being $55,067 with a bachelor's degree, $64,759 with a master's degree, and $77,364 with a doctorate degree. This places industrial engineering at 7th of 15 among engineering bachelors degrees, 3rd of 10 among masters degrees, and 2nd of 7 among doctorate degrees in average annual salary.[5] The median annual income of industrial engineers in the U.S. workforce is $68,620.
