Effect of work study & time study on production

and quality

Southeast University

Objectives of project work:

To implement of work study charts to obtain maximum utilization of the resources( Man, Machine & Materials) and to optimize workplace by changing The plant layout & workstation, using the process charts

Role of industrial engineering department in apparel industry:

Importance of industrial engineering (IE) tools that can be used to improve upon the productivity of their factories and thus enhance the profits Very few companies have been operating with a full fledged industrial engineering department and even those which boast of as an industrial engineering department(IED) in their factories are not allowing freedom and scope to function to its full capabilities The role of IED is important for the garments industry for the following two reasons:

garments manufacturing industry.

Fabric from stores

Topics covered during the project work:

• Plant layout & workstation design.

• work study & time study concepts on production and quality

Workstation Design:

Workstation Design are described

below-1 Space requirements

2 Consideration of the space requirement for the movement of

material handling equipment

3 Easy access to safety stops in case of emergency

4 Easy access to machine for inspection and lubrication,

maintenance and repair

5 Space between one machine to another machine

6 Appropriate ventilation, lighting & safety

Work Study

Measurement

What is work study?

 Work study is mainly concerned with the examination of human work.

There are two parts of work study:

• To eliminate wastage of time and labor.

• To reduce fatigue and boredom of work by avoiding unnecessary

movements.

• To find a best way of doing a job.

• To have more utilization of materials, machines and workers.

• To improve the design of work place layout.

• To standardize the method, obtained after conducting the motion

Work Measurement Techniques

 Time Study: Directly observing an operator.

 Pre-Determined Motion Time Study System: Analyzing the motions

used to carry out the activity.

 Analysis of Past Records: Using previous records/ Studies available

in the factory.

To determine the time it should take

for a qualified worker to perform a

specific task using a specified method

by directly observing an operator.

For this process operation is 2, but making time taking around 10 min seam joining uneven, seam, broken stitch, puckering needle hole and down grade quality etc defects are coming more which clearly indicate that garment piece handling by the operator are not proper, they need to trained how to handle the fabric or the proper method of stitching the garment

 PDCA

Figure : The Shewhart Cycle is a fundamental idea for continuous process improvement.

The benefits of TQM can be classified into the following two categories:

1 Customer satisfaction oriented benefits.

2 Economic improvements oriented benefits.

1 Customer satisfaction oriented benefits: The benefits under this category are listed below:

(a) Improvement in product quality.

(b) Improvement in product design.

(c) Improvement in production flow.

(d) Improvement in employee morale and quality consciousness.

(e) Improvement of product service.

(f) Improvement in market place acceptance.

2 Economic improvements oriented benefits: The benefits under this category are as follows:

(a) Reductions in operating costs.

(b) Reductions in operating losses.

(c) Reductions in field service costs.

Process Name = Side Seam

Observed Time = 35.27 Sec

Some suggestions:

 Operation are not

 Material movement is minimized

 Material handling is minimized

APPAREL MANUFACTURING, THE EFFECTIVE UTILIZATION OF

RESOURCES ( MAN, MATERIAL & MACHINES) CAN BE

ACHIEVED

MINIMUM AND A SOLUTION CAN BE DERIVED IN A SHORT

PERIOD OF TIME
