Industrial Engineering

Industrial engineering is the branch of engineering that concerns the development, improvement, implementation and evaluation of integrated systems of people, knowledge, equipment, energy, material and process. Industrial engineering draws upon the principles and methods of engineering analysis and synthesis. It eliminates waste of time, money, materials, energy and other resources. Industrial Engineering is also known as Operations management, Production Engineering, or Manufacturing Engineering depending on the viewpoint or motives of the user. In lean manufacturing systems, Industrial engineers work to eliminate wastage of time, money, materials, energy, and other resources.

All engineers work in planning, designing, implementing and controlling the systems that enable people to use technology. Industrial engineers in turn design systems that enable people and society to improve productivity, efficiency, effectiveness, and quality. The industrial engineer has a dual role, both to extend the human capability to operate, manage and control the overall production system, and to ensure the safety and well-being of those working in the system.

The process of engineering always starts with measurement. Where other engineers might measure temperatures, pressures, or loads, the industrial engineer measures the time of a work cycle, the dollar value of expenditures, rates of machine failures, and demand for finished goods. Usually, the mathematical analysis must take into account risk and uncertainty to a larger extent than in other engineering fields.

Theses systems are broadly designed and are characterized by a need to integrate both the physical and decision-making capabilities of humans with all aspects of the system design. Problems can range from the design of a factory floor to the overall corporate plan for procurement, production, and distribution. Industrial engineers are found in nearly every industry including healthcare, energy, and communications.

Process of Industrial engineering

Method, operation, process, task etc. are used in the context of improving production and engineering activities in organizations. The term “Method” was popularized by method study and methods engineering subjects. The term process was popularized by Gilbreth when he developed process charts. In the process chart, operation is one of the activities. Task was used by Taylor. Process seems to be more popular terminology now as process planning,  process orientation and process mapping became popular terms. Industrial engineering carried on processes to do productivity improvement and reduce cost is termed as process industrial engineering. Product industrial engineering and process industrial engineering, redesign of products and processes for productivity improvement and cost reduction are the core engineering activities in industrial engineering.

Production methods or processes efficiency engineering was indicated by Henry Towne in his 1886 paper. He specially emphasized that engineers managing manufacturing shops and works have to focus on reduction of cost of production and do engineering changes to achieve it. A logical and systematic procedure for reducing costs, increasing production without an impairment to quality was described by F.W. Taylor in his 1895 paper. Since then, many more improvement ways were added to the industrial engineering of processes.
