The garment industry has played a pioneering role in the development of industrial sector of Bangladesh. The RMG sector is expected to grow despite the global financial crisis of 2009.As China is finding it challenging to make textile and foot wear items at cheap price, due to rising labor costs, many foreign investors, are coming to Bangladesh to take advantage of the low labor cost. Though Bangladesh produces garment with lowest cost but poor productivity. To survive and prosper in today's economic times, companies can no longer manage using financial measures alone, they have to track non-financial measures also such as customer satisfaction, brand preference, speed of response, employee satisfaction etc.Productivity can improve by applying lean tools like- 5s, JIT, Muda, Root Cause analysis, KPIs, VSM. For improving the ultimate productivity OHS of RMG sector of Bangladesh should be improved. In Ready Made Garments (RMG) sector of Bangladesh, the employees represent an organization's biggest and its most valuable asset. The company's productivity, and ultimately, its profitability depend on making sure all of its workers perform up to their full potential. This paper summarizes that how KPIs analysis improve productivity and OHS of RMG sectors. Appropriate indicators are first selected for KPI scoring then simulate the scores with the help of Adaptive Network-based Fuzzy Inference System (ANFIS) and finally illustrated how KPIs impacts on overall productivity.

3. The garment industry played a pioneering role in
the development of industrial sector of
Bangladesh. Bangladesh's exports industry alone
comprised USD 31.2 billion in FY 2014-15,
81.69% of which was made up by ready-made
garments.
Improving the productivity of RMG industries can
be profitable for our country .Productivity can
improve by applying lean tools like- 5s, JIT,
Muda, Root Cause analysis, KPIs, VSM.
4. To survive and prosper in today's economic
times, companies have to consider both
-financial measures
-non-financial measures (customer &
employee satisfaction etc
We have done our study based on a
renowned garments industry and try to
improve its overall production by improving
its schedule, layout , line balancing, OHS
structures & reducing waste .

10. What Is Scheduling?
Assigning an appropriate number of workers to
the jobs during each day of work is called
scheduling. Scheduling is that phase of
production control which rates the work in the
order of its priority and then provides for its
release to the plant at the proper time and in
the correct sequence
11. Step 1: Identify Available Time
Step 2: Schedule Essential Actions
Step 3: Schedule High-Priority Activities
Step 4: Schedule Contingency Time
Step 5: Schedule Discretionary Time
Step 6: Analyze Your Activities
12. Scheduling is the way we actually manage a project.
Without scheduling, nothing or nobody is managing
the project and hence amounts to failure of a
project. Scheduling describes guidance and pathway
for a project to run.
It defines certain milestones and deliverables which
need to be achieved on a timely basis for successful
completion of a project. Monitoring the schedule
provides an idea of the impact the current problems
are having on the project, and provides opportunities
to enhance or reduce the scope of a milestone/phase
in the project.

27. Line balancing means allocation of machine or work to
individual operation.
In garments industry , line balancing is the process of
-Selecting an effective production line
-With competent machines regarding to worker
-To produce a specific order
- A certain time deadline
We used line balancing technique to achieve :
1.The minimization of the number of
workstations
2.The minimization of cycle time
3.The maximization of workload smoothness
4. The maximization of work relatedness
- To improve per day production
- To minimize the production cost
28. To maximize the production
To improve per day production
To minimize the production cost
To find out the wasting time during a product making and
to minimize the wasting time
Find out the problem restricting the production,
generating proper solutions and implement them in a
proper way
To analyze what affects productivity in respect to a
garment factory
To develop the best method
To balance the line for best utilization of men , machine
and material.

will be gained when we add extra 7 machines. Then the no of
machines will =(12+7)=19.
Balancing case no.2:In Ironing section the required capacity
will be gained when we add additional 6 machines. Then the
no of machines will be=(10+6)=16.
Balancing case no.3: In PQC section we remove 5 machines
.Then the no of machines will be =(20-5)=15.
Balancing case no.4 :In packing section, there are 17
workstations available. If we remove 8 workstations, then
the required capacity will be gained.
When we balance these all sections, all of these sections will
follow the Takt time(10 min).

37. Lean manufacturing:
Eliminating any kind of waste within a manufacturing system that
does not add value to the product is called ‘lean manufacturing’
or ‘lean production’, often simply lean.
Muda:
Anything in the manufacturing process that does not add value
from the customer’s perspective.
VSM( Value Stream Map):
Value stream mapping (VSM) is a lean manufacturing tool that
seeks to map a process from supplier to customer, highlighting
the flows of product and information and identifying delays
and non-value adding processes.

48. What is KPI?
Key performance indicators (KPI) are a set of
quantifiable measures that a company uses
to gauge its performance in terms of meeting
their strategic and operational goals over
time.
Also referred as Key Success Indicator(KSI)
49. Why Should KPI Analyzing is needed?
Determine present performance level
Assess whether its manufacturing system
need to be improved
Analyze where need improvements
Work on that critical points and improve it
By improving keeps a company on track
50. In this study for assessment of a RMG industry's
maturity mainly focuses on two sectors –
OHS maturity assessment
Lean maturity assessment.
52. Employee Involvement in improvement
Training for improvement
Value Stream Mapping
5S/ Housekeeping
Preventive Maintenance
53. For Analyzing KPIs ANFIS tool has been used
What is ANFIS?
Adaptive Neuro-Fuzzy Inference System
Similarly to neural networks
it integrates both neural networks and Fuzzy logic
principles, it has potential to capture the benefits of
both in a single framework
54. How it works?
Using a given input/output data set, the toolbox
function ANFIS constructs a fuzzy inference system
(FIS)
Whose membership function parameters are tuned
(adjusted) using either a back propagation algorithm
alone or in combination with a least squares type of
method. This adjustment allows your fuzzy systems
to learn from the data they are modeling.
61. For OHS Maturity Assessment : 2.7 (poor but acceptable)
For Lean Maturity Assessment : 3.3 (Acceptable)
Output of OHS M.A Output of Lean M.A
62. Expanded into more data sets.
Implemented in different industries.
Other methods can also be used or combined.
Other methods can be used to determine the criteria.
Increased sufficient data sets, more predictable data
and more precise results.
More experts’ opinion can give the result more
accuracy.
Increased the number of membership function or
rule, and selection input
parameters.
63. Important to perform KPIs analysis.
Necessity of performance measurement tool.
ANFIS provide more accuracy on prediction.
Applicable to other companies.
