Garment Production System

 In simple a ‘garment production system’ is a way how

fabric is being converted into garment in a

manufacturing system

 The choice of best apparel production system depend on the Product, The Policies of the Company and the

capacities of manpower

 There are basically three Production systems:

I Progressive Bundle System

II Unit Production System

III.Modular Production System

1 Progressive Bundle System

(PBS)

 Also Called Material Handling System

 As name implies the bundle of garment parts move from operation to operation

 Traditional Production system

 Widely used by apparel manufacturers for several

decades and still today

 80% apparel manufacturers use the Bundle system

(PBS)

PBS Workflow

 Bundles consist of garment parts needed to complete a specific

operation (e.g an operation bundle for pocket setting might include shirt fronts and pockets to b stitched together.

 Some firms operate with a standard bundle size, while other vary bundle sizes acc to size of pieces in bundle and operation to b

completed.

 Bundles are assembled in the cutting room, where cut parts are matched up with corresponding parts and bundle tickets.

 Workers (labour) transport and move Bundles of cut parts to sewing room via trollies.

 Operator scheduled to complete the operation and perform same operation on all pieces in the bundle, retie the bundle, remove

Bundle ticket and move bundle for next operation.

Progressive Bundle System

Advantages of PBS

 Labor of all levels ie unskilled, skilled, semi skilled

labors are involved Small simple operations

 Quantity of each operation is checked during every

single operation thus quality is good

 Due to bundle system, less chance of mixing up of

parts…thus less confusion

 Bundle tracking is possible, so identifying and solving problems become easy

 Effective production control system and Quality control system

Dis-advantages of PBS

 Time Consuming due to assembling, moving and

un-tieing of bundles

 More labor…More labor cost

 Needs efficient supervisor

 Labor absentiees can effect production due to

incompletion of contracts

 Variety of styles and less quantity is not effective in this system

 Proper planning is required for each style, each batch

 Improper planning causes labour turnover, poor quality, less production, etc

2 Unit Production System (UPS)

 A Unit Production System is a type of layout that uses

an overhead transporter system to move garment

components from work station to work station for

assembly

 In UPS, there are hangers One hanger have multiple clips containing all parts of the single garment

 All parts for the single garment are advanced through stitching line together by means of hanging carrier that moves along an overhead conveyor

 Hanging carrier can be moved manually by the

operator using button after completion of single

operation or By computerized system that move the

conveyor after a specific fed throughput time

UPS Workflow

 Load all the pieces of single garment in a product carrier.

 The product carrier with the pieces will be routed through the different operation steps.

 At every machine/operation the patented chain will position the product ideally.

 Completed the product arrives to an unloading

station The empty product carrier returns to the loading station.

Unit Production System

Advantages of UPS

 Bundle Handling completely eliminated.

 The time involved in the pick-up and disposal is reduced to minimum.

 Output is automatically recorded, eliminates the operator to register the work.

 The computerized system automatically balance the work between stations.

 Improved lead times-less work in process.

 Improved space utilization (more machines can be adjusted)

Advantages of UPS (Cont.)

 Increased Productivity.

 Throughput time can be drastically

reduced.

 Indirect labor costs are reduced (by elimination of bundle handling and

requiring fewer supervisors)

 Improved production and quality.

Dis-advantages of UPS

 Unit Production system requires high

investment.

 Proper planning is required to be effective.

 Highly expensive-buying equipment and cost of installing.

 Specialized training for the system.

3 Modular Production System

 A Modular Production System is a contained,

manageable work unit that includes an empowered work team, equipment and work to be executed

 The number of teams in a plant varies with the size and needs of the firm and product line

 Usually there are 4-15 labors in one team depending

upon the type of garment to be stitched and skills of

labor

 Teams may be used to perform all the operations (whole garment production) or certain portion of assembly

operations

 Team is responsible fro maintaining a smooth work flow, meeting production goals, quality level

Modular Production System

 Team members develop an interdependency to improve the process and accomplish their goals.

 A worker in a team can perform Multiple functions depending upon his skills (Multi-skills).

Modular Production System

Advantages of MPS

1) High Flexibility.

2) Fast throughput times.

3) Low wastages.

4) Reduced absenteeism.

5) Empowered employees.

6) Improved Quality.

Dis-advantages of MPS

 A high capital investment in equipment.

 High investment in initial training.

 No compatibility between team members can cause problems thus loss in production…

 Dependency on the Team for whole Production.
