shape Introduction

What is Industrial Engineering? Industrial Engineering is the branch of engineering concerned with the design and operation of industrial processes. It is also known as the branch of engineering that involves figuring out how to make or do things better. "Industrial engineering is an inter-disciplinary profession that is concerned with the optimization of complex processes, systems, or organizations by developing, improving and implementing integrated systems of people, money, knowledge, information, equipment, energy and materials". Industrial engineers use specialized knowledge and skills in the mathematical, physical, and social sciences, together with the principles and methods of engineering analysis and design, to specify, predict, and evaluate the results obtained from systems and processes. [Reference: Badiru, A. (Ed.) (2005). Handbook of industrial and systems engineering]
Industrial engineers are concerned with reducing production costs, increasing efficiency, improving the quality of products and services, ensuring worker health and safety, protecting the environment and complying with government regulations. Industrial Engineering is also known as Operations management, Production Engineering, or Manufacturing Engineering depending on the viewpoint or motives of the user.
