Operation Bulletin of Polo T-shirt with Machine Layout Plan

Introduction: Operation Bulletin of a Polo T-shirt is a summary of the whole production process. In this document, the industrial engineers who work as layout planner listed all the required things to produce a Polo T-shirt. They make a summary of types of machine, no. of the machine and worker needs to complete a Polo T-shirt in the sewing line.

Common information listed in the machine layout plan:

• Name of the operation.
• Cycle time.
• Calculated production.
• Hourly production target.
• Types of machine used for each operation
• Types of operation done manually by the worker.
• No. of machine required for each operation.
• No. of worker required for each operation.

Generally, a machine layout plan is made by following an operation breakdown. Because from an operation breakdown, we get the proper idea about which part will join one after another and select the machine for that operation. We have also known how many machine and workers need for each operation from the machine layout plan.

Operation Bulletin of a Polo T-shirt: Operation bulletin of a Polo T-shirt has divided into 3 parts;

1. Sewing and production data.
2. Machine requisition data.
3. Manpower requisition data. 

1. Sewing and production data: In sewing data included SMV of Sewing and manual operation, production target per hour at 80%, 90%, and 100% efficiency.

Operation Bulletin of Sewing Data
Sewing Operation SMV	8.30 min.
Manual Operation SMV	2.02 min.
Production Target at 80% efficiency	1423 pcs
Production Target at 90% efficiency	1601 pcs
Production Target at 100% efficiency	1779 pcs

2. Machine requisition data: In machine data included types of machine and no. of machine required for this garment production.

Operation Bulletin of Machine Data
Name Of Machine	Requisition
OL – overlock	7 m/c
SNL – Single needle lock stitch	20 m/c
FL – Flat lock m/c	3 m/c
BH – Button Hole m/c	1 m/c
BA – Button Attach m/c	1 m/c

3. Manpower requisition data: In manpower data included no. of the operator and helper required for this garment production.

Operation Bulletin of Manpower Data
Operator	33
Helper	9
Total	44

Operation bulletin makes our work easy to set up a production line. We easily manage machine and operator requirement for any sewing line by this. But it is necessary to do operation breakdown of Polo T-shirt to prepare a machine layout as also operation bulletin.
