The main areas of work of an industrial engineer are :-

• Quality control
• statistical process control
• motion economy
• research & development
• product ability

Job Responsibilities:-

As an industrial engineer, you will design better methods and facilities for manufacturingand services. You will study the various industrial processes involved, use mathematical models and computer simulation to devise new manufacturing systems that are more efficient.
As an industrial engineer, you must also understand ergonomics ( which seeks to adapt working conditions to suit the worker) and consider how the machine and work environment affect the worker . You will design workstations to reduce fatigue and prevent discomfort and work related injuries. As an industrial engineer, you will ensure that the placement of equipment, computers and keyboards is perfect right down to the heights of desks and tables.
In actual plant design , an industrial engineer should figure out which computer systems, machines and automated equipment will be used in the design and manufacturing process. You will determine the most effective layout for computers, equipment and offices such that it is flexible and easily maintainable.
When new projects come up, as an industrial engineer you will be involved in it from start to finish. Industrial engineers determine the suitability of locations for factories depending on the best combination of raw materials availability, transportation and costs.
You will calculate how much each machine or worker should deliver and if necessary initiate the use of automation and robots. As an industrial engineer you will aid in financial planning and cost analysis , design production systems as well as quality control procedures.
You will also have t work out the best possible system for handling and storage of raw material, setting inventory size, as well as packaging and the physical distribution of goods and services. In addition to these responsibilities you are also concerned with worker safety and work environment.
One of the major challenges an industrial engineer faces is automating a production process. You will have to first determine what aspect of production needs to be automated and if it makes financial sense. As an industrial engineer, you will decide which machine fit the requirements.
