Production Engineering

Companies such as SAIL, NALCO, BHEL and other private production based companies like JINDAL, AMBUJA CEMENTS etc. Would need production engineers. Mechanical Engineering careers
Here a list of some of the industries a mechanical engineer might work in and the things they might be required to do:
Design vehicles, ranging from space craft to high performance racing cars.
Analyze the acoustics data for planning a building.
Design a ventilation and air conditioning system for a large building.
Design the air filtration unit for a train.
Design a suitable power system.
Design and develop next generation machines for aiding the disabled.
Develop new concepts for underground mining machinery and transport.
Use fluid structure interaction models to design rotating blades using advanced materials.
Design and manufacture industrial robots for a range of applications.

Production / Industrial Engineering are pretty much the same disciplines. The areas of study include production systems (batch / mass / etc. ), production planning and management, economics of production systems, optimization and simulation techniques, etc. The supporting core engineering disciplines like engineering design, machine tools, production technology, thermodynamics, fluid mechanics, strength of materials, material Science, are all taught as well. Manufacturing Systems Engineering is more often a graduate level course rather than an undergraduate course which focuses on production systems and practices, and their mathematical modeling. There is far less emphasis on the supporting engineering disciplines and far more focus on understanding the determinants of efficient manufacturing in different modes of production. In addition, manufacturing processes are studied in detail - from CNC's and other precision machinery, to nanotechnology.
