Manual 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

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

Straight Line or 'syncro' system

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

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

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

UNIT production system

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

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)

7 of 8

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
