Operation Breakdown of Hoodie Vest

In my industrial engineering tutorial series, I am sharing an Operation Breakdown of Hoodie Vest. You can refer to this operation bulletin to learn about various operations involved, SMV and machine requirements in making Hoodie Vest. 

A Hoodie Vest is sleeveless padding jacket. It is not an easy style to produce in the sewing line. It has lots of complex processes. Here I describe the operation breakdown of the Hoodie Vest with SMV and Machine names. 

Operation Breakdown of Hoodie Vest is done by the following table. In this operation bulletin process list, estimated time, machine name, hourly production target quantity at 100% and 60% 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.

How to set the target per hour in the Sewing line of the Garment Factory?

Formula to set the 100% target:

Daily Target = (Worker x Working hour x 60/ SMV) x efficiency %

Basic Pitch Time (BPT) =Total SMV / Total Manpower

We can set the Line target base on line efficiency and daily cost.

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