Chapter 1
Introduction to Industrial Engineering

2
1.1 Definition
 Fierce Competition in Economy.
 Customers demands are rising.
 Challenge for industries to produce goods of
right quantity, quality , in time and at
minimum cost.
 Industrial Engineering plays a pivotal role in
meeting these challenges.
 We have various techniques in Industrial
Engineering to analyse and improve the work
methods, to eliminate waste, proper
allocation and utilization of resources.

3
1.1 Definition
 American Institute of Industrial Engineers
(AIIE) defines Industrial Engineering as
follows;
 Industrial Engineering is concerned with the
design, improvement and installation of
integrated system of men, materials and
equipment. It draws upon specialized
knowledge and skills in the mathematical,
physical sciences together with the principles
and methods of engineering analysis and
design to specify, predict and evaluate the
results to be obtained from such system.

4
1.1 Definition
 The prime objective of industrial
engineering is;
1- To increase the productivity.
2- Eliminating waste and non-value added
activities.
3- Improving the effective utilization of
resources.

5
1.2 History & Development
 It is linked with industrial revolution and passed
through many phases to reach present advanced
stage.
 Frederick Taylor is named as father of scientific
management and industrial engineering.
 But before Frederick Taylor, Adam Smith gave
concept of Division of Labour through his book The
Wealth of Nations.
 Also James Watt, Boultin Mathew and Robinson
obtained a place in the history of Industrial
Engineering because of their work related with
improvements in the performance of machines and
industries.

6
1.2 History & Development
 Period between 1882-1912 was the critical
period in the history of Industrial Engineering.
Important works during this period are;
 Factory system, Owner, Engineer and
Manager concept.
 Equal work, equal pay and incentives.
 Scheduling and Gantt Charts.
 Engineers interest in cost control and
accounting.

1.3 Contributions to Industrial
Engineering
1. Adam Smith (1776): through his book titled Wealth
of Nations laid foundation to scientific
manufacturing. Through his concept of division of
labour which included the skill development, time
savings and the use of specialized machine was
able to influence.
2. James Watt (1864): Steam Engine advanced the
use of mechanical power to increase productivity.
3. Charles Babbage worked on the same line as Adam
Smith.

4- Frederick Taylor (1859-1915): was a mechanical
engineer and initiated investigations of better work
methods and develop an integrated theory of
management principles and methodologies. He
proposed following actions;
 Data Collection and standards for workers.
 Scientifically training of workers.
 Cooperation between management and labour for
better production.
 Divide work between management and labour and
assigning to those who are best suited.

5- Henry L. Gantt (1993): His contributions are;
 Work in the area of motivation field, development of
task and bonus plan.
 Measurement of management results by Gantt
Charts.
 Recognition of social responsibility of business and
industry.
 Advocated training of workers by management.
6- Frank and Lillian Gilbreth (1917): developed method
study as a tool for work analysis.
 He developed micro-motion study, a breakdown of
work into fundamental elements called therbligs.

10
Engineering
7- Harrington Emerson(1913): Developed his
managerial concepts simultaneously with Taylor,
Gantt and Gilbreth.
 Amongst his contributions is the Emerson’s Efficiency
Bonus Plan, an incentive plan which guarantees the
base day rate and pays a graduated bonus.
 He also proposed twelve principles of efficiency.
8- L.H.C Tippet (1937): Developed the concept of work
sampling to determine the equipment and manpower
utilization and setting performance standards for long
cycle, heterogeneous jobs involving team work.

11
1.4 Activities of Industrial
Engineering
 The primary activities as spelled out by
AIIE are;

12
1.5 Industrial Engineering
Approach
 In carrying out various activities, the
industrial engineer;
 Gathers and analyses facts.
 Prepares the alternative solutions taking
in to consideration all the constraints
both internal and external.
 Selects the best solution for
implementation.

13
1.5 Industrial Engineering
Approach
 At problem identification/definition stage following
steps must be taken;
1- All the facts about the operation are collected and
recorded using various recording techniques like
charts, diagrams or models.
2- Critical Examination of all facts by asking series of
questions.
3- Alternative ways are found by techniques like
brainstorming.
4- based upon the criteria fixed for evaluation, the best
alternative is selected.

14
1.6 Objectives of Industrial
Engineering
 The basic objectives of Industrial
Engineering departments are;
1- To establish methods for improving the
operations and controlling the
production costs.
2- To develop programmes for reducing
these costs.

15
1.7 Functions of An Industrial
Engineer

16
1.8 Techniques of Industrial
Engineering
 Following tools and techniques are used to improve productivity
of the organization by optimum utilization of resources.
1- Method Study.
2- Time Study (Work Measurement).
3- Motion Economy.
4- Financial and Non Financial Incentives.
5- Value Analysis.
6- Production, Planning and Control.
7- Inventory Control.
8- Job Evaluation.
9- Material Handling Analysis.
10-Ergonomics (Human Engineering).
11- System Analysis.
12- Operations Research Techniques.

17
1.9 Place of Industrial
Engineering in Organization

18
1.10 Industrial Engineering in
Service Sector
 Large number of industrial engineers
are in demand and attracted to careers
in exciting, challenging and rewarding
new fields.
 The various service industries are;
1- Health Service.
2- Government Organizations.
3- Banking.
