Industrial Engineering Focus and Scope Operations Engineering and Management Work Design and Measurement Engineering Management Operations Research and Analysis Product Design and Development Engineering Economics Analysis Supply Chain Management Facilities Engineering and Energy Management Quality & Reliability Engineering Ergonomics and Human Factors Safety Information Engineering System Design and Engineering Mechanical Engineering Focus and Scope Acoustical engineering concerns the manipulation and control of vibration, especially vibration isolation and the reduction of unwanted sounds, Automotive engineering, the design, manufacture and operation of motorcycles, automobiles, buses and trucks. Energy Engineering is a broad field of engineering dealing with energy efficiency, energy services, facility management, plant engineering, environmental compliance and alternative energy technologies. Energy engineering is one of the more recent engineering disciplines to emerge. Energy engineering combines knowledge from the fields of physics, math, and chemistry with economic and environmental engineering practices. Manufacturing engineering concerns dealing with different manufacturing practices and the research and development of systems, processes, machines, tools, and equipment. Materials Science and Engineering, relate with bio materials, computational materials, environment and green materials, science and technology of polymers, sensors and bio electronics materials, constructional and engineering materials, nano materials and nanotechnology, composite and ceramic materials, energy materials and harvesting, optical, electronic and magnetic materials, structure materials. Power plant engineering, field of engineering that designs, construct and maintains different types of power plants. Serves as the prime mover to produce electricity. Thermal engineering concerns heating or cooling of processes, equipment, or enclosed environments: Air Conditioning; Refrigeration; Heating, Ventilating, Air-Conditioning (HVAC) and refrigerating. Vehicle engineering, the design, manufacture and operation of the systems and equipment that propel and control vehicles.
