Operation Bulletin of a Swim Short

In my Industrial Engineering (IE) tutorial series, I am sharing an operation bulletin of a Swim trunk. You can refer to this operation bulletin to learn about various operations involved and machine requirements in making Swim trunk. But in this post, I describe the operation bulletin of a Swim Short also known as a Swim trunk.

Operation Bulletin of a Swim Short

Operation Breakdown of a Swim Short is done by the following table. In this Operation Bulletin, Operation list, estimated time, Machine name, Hourly production target quantity at 100% and 70% efficiency are shown. The estimated time (SMV) shown in the below table will vary according to the product method followed and machine and equipment used in actual production. So please be careful while you use the above estimated time against each operation.

Operation Bulletin makes our work easy to set up a production line. We easily manage machine and operator requirements for any sewing line by this. But it is necessary to do an operation breakdown of Swim Short to prepare a machine layout and line balancing by industrial engineering (IE). 

Please keep in touch with my page to know the update. Visit here to know what is operation breakdown in the garment industry.

Thank you for your patience reading. Please, Share this article with others. It will inspire me to write more about this.
