Functions of Industrial Engineering

The functions of management are currently given as Planning, Organizing, Resourcing, Executing and Control.

What are functions of Industrial Engineering (IE)?


Industrial engineering has the following functions:

Research in Industrial Engineering
Productivity Science
Productivity Engineering
Productivity Management
Communication, Training and Implementation
Productivity Measurement
Review



Research in Industrial Engineering


Industrial engineering has emerged out of shop management and scientific management developed and promoted by F.W. Taylor. Development of science related to production systems or work systems consisting of machines and men is the foundation for this subject. Hence research is an important function of industrial engineering. Industrial engineers are to be taught scientific research method and process so that they can understand the research papers published by IE researchers and also undertake research related to local applications.


Productivity Science


Research propositions and the tests of research propositions are to be consolidated into scientific theories related to various issues of interest in the field of industrial engineering.

Productivity Engineering


Redesign of engineering processes to make them more productive is productivity engineering. The two important outputs of engineering processes are products or services and processes to produce those goods and services. Redesign of human actions also is part of productivity engineering. Productivity engineering is driven forward by productivity science. Improvement iterations take place within productivity engineering itself due to inventions taking place.

F.W. Taylor who is the father of productivity engineering of processes and L.D. Miles, father of productivity engineering of products strongly stated that productivity engineering has to maintain the effectiveness or quality of the basic engineering product or process designed by the design engineering team. Industrial engineering as theory and practice does not in any reduce the effectiveness or quality of the systems they are redesigning.

Productivity Management


Productivity management consists of activities of industrial engineers in the field of management. These activities have two objectives. One objective is to assess various management policies, programs and processes for the impact on productivity of engineering processes. Where they do not have desirable effects, industrial engineers have to propose redesign of them.

The second objective is the management of productivity in organizations. Industrial engineers are responsibility for managing the productivity. They have to plan for productivity improvement, organize for it, acquire resources for it, executive productivity improvement projects and activities and control them to achieve the planned goals.

Productivity science gives impetus for developing management methods that increase productivity. Thus productivity science is an input to productivity engineering and productivity management.


Communication, Training and Implementation


Industrial engineering is carried out as staff activity. The redesigns of the IE projects are to be communicated to various persons in the organization to establish its feasibility and also get them approved by competent authorities for funding. Then, industrial engineers have to train various persons in the new methods. Even though, they are a staff function, they have to be part of implementation teams and their work is not over till implementation is done.

Productivity Measurement


Measurement of productivity is an important function. After productivity improvement projects are implemented, measurements have to validate the improvement. Also past measurements or new measurements become the basis for planning productivity improvement programs.

Review


Based on the productivity measurements, a review of situation is to be made to take decisions regarding future efforts in the area of productivity. The results of review become the sources for further research, productivity engineering and productivity management activities.


The principles of industrial engineering proposed by Dr. K.V.S.S. Narayana Rao - Presented at the 2017 Annual Conference of Institute of Industrial and Systems Engineers (IISE) - at Pittsburgh, USA are the basis for deriving the functions of industrial engineering.

Industrial Engineering in All Branches of Engineering - Principle of Industrial Engineering

Industrial engineering defined as system efficiency engineering has application in all branches of engineering. Productivity improvement is needed in engineering systems of all branches and therefore industrial engineering needs to be used in all branches of engineering. It needs to be taught in all engineering branches.

One can see all functions of industrial engineering can be performed in engineering activities of all engineering branches. It is from the successful and effective application industrial engineering in all engineering branches that industrial engineers can go to other disciplines and initiate productivity improvement activities by involving specialists in those disciplines to investigate productivity improvement.

Focus Areas of Industrial Engineering


Productivity Science

Product Industrial Engineering

Process Industrial Engineering

Industrial Engineering Optimization

Industrial Engineering Statistics

Industrial Engineering Economics

Human Effort Industrial Engineering

Productivity Measurement

Productivity Management

Applied Industrial Engineering

Objectives of Basic Engineering and Industrial Engineering


Engineering has two aims: 
To develop effective products and processes that satisfy customers. 
To develop efficient products and processes that give profits and satisfaction to the producers (both managers-capitalists and employees). 
Industrial engineering is focused on efficiency while the functional engineers are focused on effectiveness. 
Both engineering streams have big data bases of knowledge, information and data that are to be used to do the design and execution work successfully to the satisfaction of customers.

  1. Very informative and lucid presentation on Industrial Engineering. The 21 principles outlined in the presentation are an evolution of the principles of IE relevant to the current era of 21st century. Defining IE as Human Effort Engineering and System efficiency engineering provides a new perspective to look at IE. The point of view on effectiveness and efficiency improvements, productivity improvements at system level, commentary on the current misconceptions about IE and the correct perspectives are very insightful.
