This document discusses a case study on optimizing manpower usage through time study methods at Mahindra HINO Motors. The objectives were to minimize excessive manpower, production time, and efforts while improving production methods and ergonomics. Through time study analysis of operations like raw material unloading, inspection, numbering, and loading, solutions like hydraulic lifters and pneumatic numbering machines were implemented. This reduced the total time for a cycle from 270 seconds to 60 seconds, minimizing manpower requirements by 2-3 people per cycle while meeting objectives.

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
