Industrial Engineering is a branch of engineering focused on optimizing complex processes, systems, and organizations. It combines principles from engineering, mathematics, and social sciences to improve efficiency, productivity, and quality in manufacturing and service industries. Industrial engineers analyze workflows, design efficient systems, and implement solutions that integrate people, technology, materials, and information. They work on improving production processes, supply chain management, quality control, and ergonomics. The ultimate goal is to streamline operations, reduce costs, enhance performance, and ensure safety and sustainability in various industrial settings.
