Industrial engineering is a field of engineering that focuses on optimizing complex systems, processes, and resources to enhance productivity, efficiency, and quality in the production of goods and services. Industrial engineers apply scientific principles, mathematical methods, and engineering techniques to streamline operations and eliminate wasteful practices. They analyze and design workflows, considering factors such as time, cost, materials, and human resources. They identify bottlenecks, develop performance metrics, and implement strategies to improve overall system performance. Industrial engineering can also utilize computer simulations and data analysis to help businesses make informed decisions.
