- - - - Advantages
        
        Automatically moves garment parts from one work place to the next
        
        Can be moved manually or via computer
        
        Machinery can be adjusted
        
        Increases productivity and quality
        
        Reduces labour costs
      - Disadvantages
        
        High Investment required
        
        Required in-depth planning
        
        Handling equipment is highly expensive
        
        Special training is required for labour
  - - - Advantages
        
        Flexibility is high
        
        Low wastage
        
        Employee absence will be low
        
        High quality production
      - Disadvantages
        
        Equipment cost is high
        
        Employee training is high
        
        Team members are much more dependant on each other
- - - - Low Costs
      - Low Risk
      - Use one or more number of M/CS
    - - High fabric waste
      - Much more time required
- - - - Low Fabric Waste
      - Less time required
    - - Cost is High
      - Risk is High
      - Much machinery is required
- - - - Section or Processes system:
        In section or processes system more skilled operators are needed to sew garment part from beginning to the end. This system includes a small influence of personnel changes and easy style changes. Sewing room has a number of sections; to complete all the operations for every garment component required more versatile operators. When one section ends then it is passed on to the next section. But this system is required more time. This section produce garments according to style. Some working steps are:
        
        Pre-assembling (preparation of making small parts)
        
        Front side making
        
        Back side making
        
        Main-assembly (closing, setting collar and sleeves,..)
        
        Lining making
        
        Setting linings
        
        Finishing operation
      - Piece rate production system:
        In piece rate production system, operators are getting their payment according to their production pieces of garment (how many pieces are they produced). It is one of the most famous production systems for both small and large apparel factories.
      - Clump system:
        In the clump system operator collect the garment part from the worktable and start the operation. After finish the work, he returns it to the worktable. A worker for the second operation then continues the work and so on. It is the continuous process until the whole garment has been assembled. This process is work like that Collection – Work –Return
      - Flexible flow system:
        In this system numbers of operators are needed for each operation. Number of machine are arrange according to the flow of work. It can be planned using the accurate number of operations in sequence. For style A garment, operator 1 do his operation one then send it to operator 2. After completing the one and second operations, operator 2 sends the both operation to the operator 3. After operation 3, the work is continued by the two operators performing operation 4 and so on.
      - One piece flow system or Progressive bundle system:
        Progressive Bundle System (PBS) is also called one piece flow system or material handling system. It is a traditional production system that widely used in garment manufacturing from early period to still now. After complete the fabric cutting, then various components of fabric parts are to make bundle and distributed to the sewing section. Bundle ticket is attached to cut parts. One operator is tried to perform the same operation on all the parts in the bundle. When one operator finish his/her work then garment bundles are move from other operator. For sewing a garment, numbers of operators are needed. Bundles are handling by the Tied bundles, Bags, Pocketed bags, Boxes and baskets, Bundle trucks, etc
      - Straight-line or Synchro- system:
        To do garment manufacturing process, different operations are divided into several parts but the fixed the same time to complete this operation. To complete only one garment group of operators are needed. When one group of operators finish their work then it pass to the next operator. Distribution may be done hand by hand or a conveyor belt
        In synchro- system different garment parts like collars, sleeves, cuffs, pocket etc with the same size, color can be processed together. When all is done then all parts are send central line for assembling a complete garment.
