industrial engineering: see engineering Chemical engineering deals with the design, construction, and operation of plants and machinery for making such products as acids, dyes, drugs, plastics, and synthetic rubber by adapting the chemical reactions discovered by the laboratory chemist to large-scale production.

industrial engineering

Application of engineering principles and techniques of scientific management to the maintenance of high levels of productivity at optimum cost in industrial enterprises. Frederick W. Taylor pioneered in the scientific measurement of work, and Frank (1868–1924) and Lillian (1878–1972) Gilbreth refined it with time-and-motion studies. As a result, production processes were simplified, enabling workers to increase production. The industrial engineer selects tools and materials for production that are most efficient and least costly to the company. The engineer may also determine the sequence of production and the design of plant facilities or factories. See also ergonomics.

industrial engineering [in′dəs·trē·əl ‚en·jə′nir·iŋ]

(engineering)

A branch of engineering concerned with the design, improvement, and installation of integrated systems of people, materials, and equipment. Also known as management engineering.

Industrial engineering

A branch of engineering dealing with the design, development, and implementation of integrated systems of humans, machines, and information resources to provide products and services. Industrial engineering encompasses specialized knowledge and skills in the physical, social, engineering, and management sciences, such as human and cognitive sciences, computer systems and information technologies, manufacturing processes, operations research, production, and automation. The industrial engineer integrates people into the design and development of systems, thus requiring an understanding of the physical, physiological, psychological, and other characteristics that govern and affect the performance of individuals and groups in working environments.

Industrial engineering is a broad field compared to other engineering disciplines. The major activities of industrial engineering stem from manufacturing industries and include work methods analysis and improvement; work measurement and the establishment of standards; machine tool analysis and design; job and workplace design; plant layout and facility design; materials handling; cost reduction; production planning and scheduling; inventory control, maintenance, and replacement; statistical quality control; scheduling; assembly-line balancing, systems, and procedures; and overall productivity improvement. Computers and information systems have necessitated additional activities and functions, including numerically controlled machine installation and programming; manufacturing systems design; computer-aided design/computer-aided manufacturing, design of experiments, quality engineering, and statistical process control; computer simulation, operations research, and management science methods; computer applications, software development, and information technology; human-factors engineering and ergonomics; systems design and integration; and robotics and automation.

The philosophy and motivation of the industrial engineering profession is to find the most efficient and effective methods, procedures, and processes for an operating system, and to seek continuous improvement. Thus, industrial engineering helps organizations grow and expand efficiently during periods of prosperity, and streamline costs and consolidate and reallocate resources during austere times. Industrial engineers, particularly those involved in manufacturing and related industries, work closely with management. Therefore, some understanding of organizational behavior, finance, management, and related business principles and practices is needed.
