Depending on the subspecialties involved, industrial engineering may also overlap with manufacturing engineering depending upon the point of view of user. It is a very broad area which includes the design and development of products. The manufacturing engineering discipline has very strong overlaps with material management, operations management and Automation. The manufacturing processes are realized with effective implementation of automation. The application of automation in a factory leads to higher consistency and quality, reduction of lead times, simplification of production, reduced handling, improved work flow, and improved worker morale. On other hand Operation Management is an important area which is responsible for designing and controlling the production in industries. It involves the responsibility of ensuring that business operations are efficient in terms of using as few resources as needed, and effective in terms of meeting customer requirements. It is anxious with managing the process that converts the input i.e. (raw materials) into output (new product).

Healthcare engineering and Management approaches the health care systems and other constructs affecting health and safety as complex systems, it identifies and applies engineering design and analysis principles in such areas.

Human factors & Ergonomics is a scientific principle concerned with understanding of interaction between human and the equipment’s, material handling in the work place, designing, evaluation & modeling of the product and manufacturing applications.

Robotics is the application of mechatronics and automation to create robots, which are often used in manufacturing to perform tasks that are dangerous, unpleasant, or repetitive. These robots may be of any shape and size, but all are preprogrammed and interact physically with the world. To create a robot, an engineer typically employs Dynamics and Kinematics, manipulation, power source, sensing, legged locomotion and Interaction. Robots allow performing the activities that are not able to do by humans and to ensure better quality in production. Many industries employ assembly lines of robots, and some factories are so robotized that they can run by themselves.

Production and logistics gets right to the heart of the supply chain, from sourcing raw materials to delivering finished products to customers. Modern production and logistics methods are growing ever more complex. In Business Process, you will apply advanced software tools for enterprise resource planning and integer linear programming problems, capacity analysis of production systems, distribution planning and vehicle routing.

Designing a new process to manufacture a certain product a certain operation requires careful planning and resources. Incorporating industrial engineers into the process design to create an Ecologically Sustainable Organization (ESO) will benefit the business in reducing the amount of waste that acts as a by-product of the system. This ideal state can be reached by limiting energy use and materials through product redesign, using renewable materials.

Engineering economics involves formulating, estimating, and evaluating the economic outcomes when alternatives to accomplish a defined purpose are available. Some other topics that may be addressed in engineering economics are Value Engineering, Cost Engineering, Tax Credits, and Investment Engineering.
