Industrial Engineering of Systems - System Industrial Engineering
Industrial engineers work on functional designs created by various engineers and managers and make them more efficient by improving resource use efficiency. Industrial engineers are to be associated with systems design or engineering process to make systems more efficient right from the first design stage. Presentation at a Global Conference on the topic (made in 2010 in Tokyo) is included in the article.

Have you industrial engineered your systems?
The Toyota man, Ohno said industrial engineering is profit engineering. If you have not industrial engineered your systems, you are leaving potential profit on the table. Industrial engineering is a set of techniques to evaluate your systems' functional designs for efficiency. Wherever there is scope, IE will improve the system's efficiency. What is efficiency? Efficiency or productivity is output/input. A functionally designed system is expected to achieve certain output. Actually the system is designed for a specific installed capacity. Industrial engineers work on this functional design and reduce resource input.
What is Industrial Engineering?
"Industrial Engineering is Human Effort Engineering and System Efficiency Engineering. It is an engineering discipline that deals with the design of human effort and system efficiency in all occupations: agricultural, manufacturing and service. The objectives of Industrial Engineering are optimization of productivity of work-systems and occupational comfort, health, safety and income of persons involved."
Industrial engineers make special efforts to confirm that no quality deterioration takes due to increasing output from machine-man combinations. They demonstrate that same quality is produced after increase in productivity and reduction in cost of production and product.
The definition emphasizes human effort engineering and system efficiency engineering.

Industrial engineering is redesign of engineering system both products and production system to make them productive and economical. Industrial engineering improves efficiency and reduces cost of production and products. Reduction in costs permits companies to sell products at lower prices and increase sales. Thus industrial engineering provides growth to companies and thus in aggregate provides growth to economy.
The redesign is done immediately after the original designers come out with the design and also many times later during the operation of the production system or production life cycle of the product.
Industrial engineering methods can be classified in these categories
1. Product Design Efficiency Engineering
2. Methods Efficiency Engineering - Production Methods Efficiency Engineering, Inspection Methods Efficiency Engineering, Maintenance Methods Efficiency Engineering, Business Processes Efficiency Engineering, Management Methods Efficiency Engineering
All resources used in methods are analysed for efficient usage. Man, Material, Money, Management, Motive Power, Machine,
3. Industrial Engineering Optimization - Engineering system problems are expressed as mathematical functions and maximum or minimum values as appropriate are ascertained to use as design values.
4. Industrial Engineering Statistics - Issues related to variability in engineering systems are decided using statistical methods - Ex. Statistical quality control, Six sigma methodology to improve process capability to determine the target central value and minimise variation of the process.
5. Industrial Engineering Economics - Use of engineering economics methodology to decide the productivity of capital used in engineering systems
6.Human Effort Engineering - Principles of Motion Economy, Motion Study to improve human effort efficiency, Ergonomics, Job Evaluation and Wage Incentives
7. Work Measurement, Cost Measurement, and Productivity Measurement
8. Management of IE studies, projects and departments
