Industrial Engineering - Core Task

The core task in Industrial Engineering (IE) is continuous engineering change in product and processes to increase productivity. Other activities are additions to this core. If it is not done, engineering term has no meaning and IE has no competitive advantage.

"Industrial Engineering is System Efficiency Engineering. " It is an engineering discipline that deals with the system efficiency." Machine Effort Industrial Engineering and Human Effort Industrial Engineering are important areas of IE.

Productivity Science

“Productivity science is scientific effort, that in any specific work situation, identifies the appropriate philosophy, culture, systems, processes, technology, methods and human physical action and behavior and elements of each of them of that will maximize positive (social, environmental and economic) outcomes relative to the resources consumed.”

in Frameworks for Productivity Science of Machine Effort and Human Effort (Proceedings of the 2020 IISE Annual Conference L. Cromarty, R. Shirwaiker, P. Wang, eds.)

Productivity Engineering

Productivity Engineering is designing and redesigning engineering elements or complete engineering systems to improve the productivity of the system and reduce its cost or the unit cost of its output.

Productivity Science is the collection of laws that indicate, facilitate and promote Productivity Engineering.

Productivity Management is managerial activities that promote Productivity Science and Productivity Engineering

Facilities Industrial Engineering

Facilities are used by processes. Facilities are common to processes. Machines are to be continuously improved. Period layout studies and readjustments are another example of facilities industrial engineering. 5S that demands upkeep of facilities is another example of facilities IE when it is implemented for the first time and proposed and initiated by the IE department. Thereafter it becomes the activity of operations management. Replacement studies are part of facilities industrial engineering.

Product Industrial Engineering

Process Industrial Engineering - Process Machine Effort Industrial Engineering - Process Human Effort Industrial Engineering.

Process industrial engineering is the popular method of industrial engineering. But, the process chart method was promoted by Motion Study books. The machine effort industrial engineering, that is improvement of machine effort, that was done by Taylor primarily to increase productivity got neglected in the evolution of industrial engineering. It is a weakness to be corrected to make IE a strong discipline.

Operation Industrial Engineering.

Process chart is a condensed version that show the entire process of producing a full product and the production of each part. The process chart is composed by symbols representing 5 operations. Operation - Inspection - Transport - Temporary Delay (WIP) - Permanent Storage (controlled store). Using process chart, the sequence of operations can be investigated and changed for more benefit. But each operation needs to be improved. It is termed simplification in process chart analysis. To do simplification information on each operation has to be collected in operation information sheets and they have to be analyzed in operation analysis sheets (Stegemerten and Maynard)

Element Level Analysis in Industrial Engineering

Elements are in Operations - We can understand the term "element" from the subject "Design of Machine Elements". Each engineering product has elements. Similarly each operation, that is part of a process has elements. Some are related to machines and tools used in the process. Some are related to human operators. Some are related to working conditions. Some are related to the work being done. Taylor first named the productivity department as "Elementary Rate Fixing Department." It has to improve each and every element in task and determine the output possible for unit time in the work element. The time allowed for that element for a piece or batch is determined through these elementary standard times or allowed times.

Efficient production (engineering) system design and efficiency improvement of production systems is the aim of industrial engineering. This fact is brought out by Hicks in the following statement.

A production system is essentially the sum of its individual operations.

Therefore, it follows that if one wants a production system to be efficient then its individual operations must be efficient. Hence Methods Engineering (Making individual operations efficient. Machine effort has to be efficient. Human effort has to be efficient) developed by Taylor, Gilbreth, Maynard and Barnes is important task of engineers.

Fundamentals of Industrial Engineering

https://nraoiekc.blogspot.com/2012/03/fundamentals-of-industrial-engineering.html

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. The concept was presented in detail by Prof. Narayana Rao, in a Presentation at a Global Conference in 2010 in Tokyo.
