Industrial and Systems Engineering is concerned with the design, improvement, and installation of integrated systems of people, materials, and equipment. It draws upon specialized knowledge and skill in the mathematical, physical, and social sciences, together with the principles and methods of engineering analysis, to design, specify, predict, and analyze the results obtained from such systems.
In a nutshell, Industrial Engineers make things work better, safer, and more economically. With its diversity, industrial engineering is used virtually in all sectors, including manufacturing, distribution, government, energy, health care and finance. A distinguishing feature of the IE discipline is the integration of humans, machines, materials and information, to optimize the performance of such systems using available resources in the most efficient way, but without degrading social and physical environments. Unlike the other engineering disciplines that focus their attention purely on the technical aspects of a system, the Industrial Engineer incorporates human and economic considerations in system design.
