5. Industrial Engineering (IE)
Industrial engineering is a branch of engineering which deals with the optimization
of complex processes, systems or organizations. Indusial engineers work to
eliminate waste of time, money, materials, manpower, machine, energy and other
resources that do not generate value.
5

6. Activities of Industrial Engineering
 Selection of processes and assembling methods.
 Selection and design of tools and equipment.
 Design of facilities including plant location, layout of building, machine and
equipment.
 Design and installation of value engineering and analysis system.
 Operation Performance evaluation.
 Supplier selection and evaluation.

7. Work study
Work study is a systematic technique of method analysis
work measurement and setting of time standard that can be
ensure the highest productivity by the optimum use of man
power, equipment and material.
7

8.  To analyses the present method of doing a job.
 To measure the work content of a job by measuring the time
required to do the job for a qualified.
 To increase the productivity by ensuring the best possible use of
human, machine and material resources.
 To improve operational efficiency.
8

9. Benefits of work study
 Increased productivity and operational efficiency
 Reduced manufacturing costs
 Improved work place layout
 Better manpower planning and capacity planning
 Fair wages to employees
 Better working conditions to employees
 Improved work flow
 Reduced material handling costs

10. Motion study
Motion study is the study of the body motions used in performing an operation, to
improve the operation by eliminating unnecessary motions, simplifying necessary
motions, and then establishing the most favorable motion sequence for maximum
efficiency.
10

11. Time Study
Time study is a work measurement technique for recording the time of performing
a certain specific job or its element carried out under specific condition and for
analyzing the data so as to obtain the time necessary for an operator to carry out at
a defined rate of performance.
Time study is a method of direct observation. A trained observer watches the job
and records data as the job is being performed over a number of cycles.
11

12. Objectives of time study
 To identify the efficiency and productivity of the company
 To set the standard time for each job.
 To set daily, monthly production target.
 To identify the efficiency of the worker.
 To evaluate a process cycle.
 To identify the qualified worker for the advanced process.
 To set basic time at a standard performance.
12

13. Time Study Tools
To do time study you need to arrange following tools
 A stop watch
 Time study format
 One pen or pencil
 Time Study board
13

14. The importance and uses of stop watch time study
 Determining schedules and planning work
 Determining standard costs and as an aid in preparing budgets
 Estimating the costs of a product before manufacturing it.
 Determining time standards to be used as a basis for labor cost control.
 Helps to know the Labor productivity, Labor efficiency, Labor Performance
 Helps to improve the process of operation.

15. Operation breakdown the job in to elements
 Elements should be easily identified, with definite beginnings and endings so that,
once established. They can be repeatedly recognized. The point at which one
element ends and another begins is called break point. Breakpoints must be
decided by the work study officer when he divides the work cycle into elements.
 All breakpoints can be recognized by a sound or by a change of direction of a hand
or arm.
 Elements should be as short as can be conveniently timed by a trained observer,
but should not be less than 0.10 minutes and more than 0.50 minutes.
 Manual elements should be separated from machine elements for future use as
synthetic data.
 Short elements should be next to long elements.

16. Basic Time
The basic time for the operation is found by applying concept of rating to relate the
observed to that of a standard place of working.

 Personal needs
 Basic fatigue
 Various other types of allowance are
 Policy allowance
 Special allowance

25. Results:
After analysis of sewing section efficiency by time study
technique the production per hour 220 pieces.
Discussion:
After analysis of sewing section efficiency by using time study
technique the production capacity increase.

26. Conclusion
Industrial engineering is an important and essential part of any Garments
Industry. One of the aims of any production system is to make total
production time as minimum as possible. This automatically reduces
inventory cost to a minimum. Sub-assembly system provides many
opportunities to economies on temporary storage and transportation space
and time. No definite answer can be given as to which is the best, as it
depends on garment style, specifications, machinery and manpower and
manufacturing policies.
