Industrial engineering is a method to improve efficiency, improve and rationalize the operation of production engineering and optimize the planning, management and design of production system through engineering knowledge and improved management knowledge.
The research field of industrial engineering is to analyze, design, improve and operate an integrated system composed of people, materials and equipment, and the technical methods needed in the research process. The purpose is to combine the principles and methods of engineering analysis and design with the professional knowledge and technology of natural science and social science, to understand, predict and evaluate the results of the integrated system, and to maximize efficiency from the overall point of view.
