Production Systems

Start to finish!

BESPOKE!
(Personalised/one off)

Supervision- Minimal, manafacturer decides everything

Productivity(amound made)- Only one

Quality Control- Done by manafacturerThroughpyt time- Very long, one off specialised item created by one person.

Layout- convient machienery, whats needed is avaliable to manafacturer

PROGRESSIVE BUNDLE SYSTEM

 BATCH PRODUCTION

• Gradually assembled through sub assembly lines
• Labour needs a vary of skills, process is broken down
• Productivity slightly higher than other systems
• QC for each individual process
• Throughput time increased at start and end of each section
• V shaped layout

More than one but less than 10thousand, examples; Gig shirts

STRAIGHTLINE OR 'SYNCRO' SYSTEM

MASS PRODUCTION

• Time very important for this production type
• Lines must be kept balanced
• High levels of labour needed due to different combination of operations
• productivity very high due to regular place
• Quality control happens during each stage of the process
• Throughput time very short due to quantity of work, somethings always being done

Has the simplest layout- STRAIGHT LINE!

STRAIGHTLINE 'SYNCHRO' SYSTEM

To be effective this system requires...

• High Volume production, lot to do at high demand
• Accurate line balancing
• Skilled supervision
• Reserve operations
• Reserve machienery and equiptment

UNIT PRODUCTION SYSTEM (UPS)

Essential features of this system include;

• Production of a single garment, not bundles
• Garments and components automatically transported from work station to work station according to pre-determind sequence
• components presented so close to workers left hand in order to reduce amound of movement required to grasp and sew the product

UPS

• Labour includes grades and rates of operators
•  Productivity is high due to workers operators working in a 'paced' enviroment, allowes development of faster working rythems
• QC happens during an inspection section of the production line
• Throughput time measured in hours not days due to low amount of work at hand
• Layout can be any form suitable to avalible area.

Quick Response Sewing system

BATCH PRODUCTION

• Supervision freed up to work with operators
• Labour must be highly skilled
• Productivity- very high product produced by one operator
• QC- in-process inspection stations are built into the line
• throughput time extriemly short due to so few garments
• layout-typical unit would have 8 stations

works alongside JIT (JUST IN TIME)

JIT

(when you order just enough fabric & components for products you want to make)

Negatives;

• if something goes wrong theres no reserves
• costs more than mass production
  

Possitives;

• No waste fabric, storage space not needed
