Types of garment production systems

Garment production system is defined as a structure in which machines, material handling, people and production processes are integrated to convert fabric into garments.

Types of garment production systems differ from each other by following factors:

How many operations does one sewing operator perform?
How many pieces flow together in the sewing line?
How are material transferred from one workstation to other?
How many pieces flow together in the sewing line?
How many machines does one sewing operator operate?

Line balancing in garment industry and how it can be improved ?

line balancing in garment industry is the technique of levelling output of every operation in a garment sewing production line.

The main objectives of balancing the line is to produce the same expected output at every process of an assembly line .There should neither be accumulation of work between two process nor absence of work between the processes. It is important to maintain this balance because in an assembly line output of one process is the input for other.

If a production line is not balanced then there would be following production problems:

Improving line Layout in garments factory for efficiency.

Improving the line layout should be the first priority if you are trying to improve the productivity or efficiency of the factory. This is because improved line layout is the foundation over which an efficient garment factory is made. In this article we will be talking about planning and improving line layout in garments factory in such a way that the productivity and efficiency is improved. To do it is important to know what is a good line layout.

How to improve efficiency of a sewing line ?

Efficiency improvement of a sewing line is a probably the most important performance indicator of garment industry but it is also one of the trickiest. The reason for that is that all the factors that affect increase in efficiency are interrelated.

Changeover time calculation in sewing line

Changeover time in sewing line is the time taken from producing the last good quality piece of the completing style to the time taken in producing the first good quality piece for the new style. Continue reading “Changeover time calculation in sewing line”

How to calculate Weighted average SAM or weighted average SMV ?

Whenever there is a need to find the average SAM, It becomes quite clear that simple average doesn’t give us the right picture. This is because simple average divides the SAM equally between all the styles. This division is wrong because there will be some styles with bigger order Quantity and some styles with lesser order quantity and the effect of order quantity will not be reflected in the averaged SAM. Therefore we need to calculate weighted average SAM whenever there is need to find average. Continue reading “How to calculate Weighted average SAM or weighted average SMV ?”

Difference Between Standard & Standardised work ?

The question “Difference Between Standard & Standardised work?” has been a confusion for quite a few people and I have seen people particularly pressing on the point that “Do not confuse Standard work with Standardised work”. I googled the difference and what I could understand from many blog posts was that Standard work means the work will not change whereas Standardized work means there is a scope of improvement. Continue reading “Difference Between Standard & Standardised work ?”

Industrial Engineering Calculations in garment production factory

Industrial engineering calculations in garment production factory is the most powerful waste quantifying and reduction tool.

These calculations are important because without setting up a target it is highly unlikely that you will be able to achieve what is expected. Once the target is set and we know what is expected we can take steps to achieve the target production. It gives industrial engineers clear picture about the performance of sewing operators, supervisors and the sewing line. The things that an industrial engineer needs to calculate are: capacity, efficiency, performance and utilization.
