Operation Bulletin of a Cargo Shorts

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

Cargo pants are pants that include two side cargo pockets and two back welt pocket with flaps. The total SMV found here is 40.78 which may vary from factory to factory. I hope this data will give you a clear idea about the process of cargo shorts and their SMV. 

Operation Bulletin of a Cargo Shorts

Operation Bulletin of a Cargo Shorts is done by the following table. In this Operation Bulletin, Operation 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.

Full form of Machine Name:

In the above table a short name of sewing machines is written. Followings are the abbreviation of those short machine codes.

• SNLS - Single needle lock stitch
• DNLS - Double needle lock stitch
• APW Machine - Auto Welt Pocket Machine
• 3T O/L - 3 Thread over lock
• 5T O/L - 5 Thread over lock
• DLM - Single needle lock stitch Edge Cutter
• FOA - Feed of the Arm
• MNCS - Multi needle chain stitch
• EH - Eyelet Hole
• SNAP - Snap Button Machine

• Manual - Helper

Set the line target:

It will be best to set the line layout target based on line efficiency, line cost and delivery date of style.

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 use “Ball Point or Sharp Point" needle to stitch this item.

Fabric Types and Needle Size Chart:

Fabric Types	Needle Size
Very fine fabrics (silk, chiffon, organza, voile, lace)	8, 9, 10

Extra heavy fabrics	20, 21

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 Bulletin of Cargo Shorts to prepare a machine layout and line balancing by industrial engineering (IE).
