Industrial Engineering is a branch of engineering dealing with the optimization of complex processes or systems. 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.
Industrial Engineering is concerned with the development, improvement, and implementation 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. Thus, industrial engineers create processes and systems that improve quality and productivity.
