1. INDUSTRIAL ENGINEERING – CASE STUDY
Optimization of Man power using Time study for
Mahindra HINO Motors
Presented by,
M8A 8351-8360

2. Problem Statement….
 The Mahindra organization engages in the
production of two product lines: engine blocks,
heads of diverse categories
 The two products have similar production
processes
 We discusses the use of Industrial Engineering
tools used for the purpose of productivity
improvement

3. OBJECTIVES
 Minimize excessive man power
 Minimize the production time
 Improve the production method
 Effort minimization
 Improvement of ergonomics
 Improve the relation between associates
and managements

4. SOLUTION ADOPTED
The Time Study (Work Measurement)
 According to British Standard Institute Time Study
can be defined as “The application of techniques
designed to establish the time for a qualified
worker to carry out a specified job at a defined
level of performance”.

5. The operations before machining for
Mahindra Hino motors
1. Raw material unloading
 Raw material is unloaded manually and it
consumes a lot of time.
 unloading of single cylinder head they required 60
sec. to 80 sec
 Solution: They installed hydraulic lifter cum trolley
of conveyer height so that they can directly place
the job on conveyer
 It reduces there efforts and time 80%.

Mahindra Hino motors….
2. Inspection
 Inspection is the necessary operation in all the
processes to neglect any defect before the
machining.
 It takes 30 sec.
 After some observation, time readings and
discussion with shop floor supervisor and
associates; They conclude that this existing time is
correct time to inspect the job that is 30sec.

Mahindra Hino motors….
3. Number punching
 Number punching is done to identify the job
 From observations it takes 90sec. For 2 associates
 Solution:They installed a pneumatic number
punching machine which need only 1 associates
per shift.
 Now the time reduced to 10sec.
4. Job loading on conveyer
 Since they installed hydraulic lifter cum trolley of
conveyer height, the existing time 90sec is reduced
to 0sec.

9. RESULT
 After the application of Industrial Engineering tool,
TIME STUDY ( WORK MEASUREMENT) they
obtained a solution which saves 2-3 man power
per cycle.
 Minimized excessive man power
 Minimized the production time
 Improved the production method
 Effort is minimised
 Improvement of ergonomics
 Improved the relation between associates and
managements
