Industrial Engineering is concerned with the design, improvement, and installation of integrated system of men, material, and machines for the benefit of mankind. It provides specialized knowledge and skills in the mathematical and physical 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 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 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.

Key Words:

Industrial Engineering, System, Logistic, Supply Chain Management, Simulation, Financial Engineering, Quality Engineering, Lean Manufacturing, PERT, CPM, Group Technology.


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 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, industrial engineering overlaps with:

* Operations Management.
* Management Science.
* Operations Research.
* Systems Engineering.
* Manufacturing Engineering.
* Ergonomics or human factors Engineering.
* Financial Engineering.
* Engineering Management.
* Supply Chain Management.
* Process Engineering.
* Systems Engineering.
* Safety Engineering.
* Cost and value Engineering.
* Quality Engineering.

Traditionally, a major aspect of industrial engineering was planning the layouts of factories and designing assembly lines and other manufacturing paradigms. Now, it is called lean manufacturing systems, industrial engineers work to eliminate wastes of time, money, materials, energy, and other resources.

Concept of Industrial Engineering:

Industrial engineering comprises scientific approaching identifying and solving the problems. Collects factual information regarding the problem analysis the problem, prepares alternative solutions taken into account all the internal and external constraints.

Selects the best solution for implementation. The major tools and techniques used in industrial engineering are:

* Production planning and control.
* Inventory control.
* Job evaluation.
* Facilitates planning and material handling.
* System analysis.
* Linear programming.
* Simulation.
* Network analysis (PERT, CPM).
* Queuing models.
* Sequencing and transportation models.
* Games theory and dynamic programming.
* Group technology.
* Statistical techniques.
* Quality control.
* Decision making theory.
* Replacement models.
* Assembly line balancing.

Objectives & Activities of Industrial Engineering:

* Improving operating methods and controlling costs.
* Reducing these costs through cost reduction programs.
* Processes and methods selection.
* Selection and design of tools and equipment.
* Facilitates planning, plant location, materials handling and storage facilities.
* System design for planning and control of production inventory, quality, and plant     maintenance and distribution.
* Cost analysis and control.
* Develop time standards and performance standards.
* Value engineering.
* Mathematical tools and statistical analysis.
* Performance evaluation.

Standard Phases of Industrial Engineering:

* Formulating the problem.
* Constructing a mathematical model to represent the system under study.
* Deriving a solution from the model.
* Testing the model and the solution derived from it.
* Establishing controls over the solution.
* Putting the solution to work for implementation.


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 would label with names of industrial engineering, production engineering, or systems engineering. 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. 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.
