Industrial and system engineering is a branch of engineering that applies analytics and critical decision-making skills to optimize complex processes, systems, networks, investments, and organizations. It is found in nearly all sectors such as finance, logistics, energy, healthcare, manufacturing, transportation, production, and telecommunications. The fundamental idea of industrial and system engineering is the use of data and experience, rather than by chance, to develop systematic and optimized solutions that help solve real-world issues. The branch of engineering uses rigorous research and data analysis to come up with new and efficient solutions.
Globally, there is an increasing need for industrial engineers, because industrial and systems engineers are the only engineering professionals that are expressly trained to be experts in productivity and quality improvement. Further, due to the rising competitiveness in the international market, organizations are adopting management philosophies that emphasize constant productivity and quality improvement, which is a niche area for industrial and systems engineers. Industrial and system engineers use statistics and facts to get in-depth knowledge and comprehension of complex systems. They then try to understand complex issues and provide solutions that fulfill specific demands while taking into account public health and safety concerns as well as cultural, sociological, and environmental aspects. The engineers then develop models that are used to produce well-balanced solutions that minimize potential hazards and maximize efficiency and productivity.
