  • 12. C & C Daily Production Schedule (CPS) Sub System Production Schedule C&C Schedule Production Schedule List List 1 4 7 2 5 8 3 6 (1) (2) (3) Output CPS Report CPS Arrangement The Registration of C&C schedule is necessary to keep the C&C System based on the production schedule. CPS Sub System includes the function to register the C&C schedule for scheduling staff according to customer purchase order. C&C start date and issue date You should input issue date every “Lot No” or “Work Order No” when you register the C&C schedule. Each C&C start date and short code is set by C&C system automatically. Decision of C&C start date You can specify the L/T in every process pattern. * L/T abbreviation for “Lead Time”. Single Wire L/T Splice processing L/T Non Single Wire processing L/T (Pre Insert, Manual Crimping) Special Wire L/T
  • 13.
    • How to get a start date in each process
    • (1). Single Wire L/T = Single Wire L/T
    • (2). Splice Wire L/T = Single Wire L/T + Splice processing L/T
    • (3). Non Single Wire L/T = Single Wire L/T + Non Single processing L/T
    • (4). Special Wire L/T = Special Wire L/T
    • (Ex.)
    •         1. Single Wire L/T 1 day
    •         2. Splice processing L/T 1 day
    •         3. Non Single Wire processing L/T 2 days
    •         4. Special Wire L/T 4 days

  • 14. Optimization Sub System BOM EFU Extraction Check List 1 2 3 (1) EFU Extraction (2) Optimization (3) Machine working load Arrangement CPS Data 4 EFU (4) Report Output The brief of Optimization Sub System is as the follows. Daily working data is extracted from CPS data and after optimization EFU data is prepared. EFU data is ordered in consideration of change time or EFU No or Process Pattern. Optimization related reports are available. (Daily Working Report, Work Load List and so on
  • 15.
    • Manual Optimization
    • You can arrange the auto optimization result manually.
    • Moving inside the same machine The order change on the specific machine
    • Moving between the machines EFU data moving between the specific machines
    Optimization Sub System This list is to confirm the man-hour and set-up time and production quantity per shift and machine. (This list is used for machine working load arrangement.) This list is to confirm the circuit information and man-hour and set-up time and production quantity per shift and machine. (This list is used for machine working load arrangement.) EFU This is a daily report to fill the EFU order and defect information and actual height information. This list is used for wire preparation. Wire type, wire size, wire flex, production quantity is outputted. This list is used for wire preparation. Wire type, wire size, wire flex and production quantity is outputted per machine..   This list is used for terminal preparation.   Directions sheet for C&C operator. This is EFU for emergency. Specify the product no and circuit, and output the EFU one by one.

  • 18. CUP Sub System
    • Purpose of the CUP subsystem is to introduce an imaginary product using multiple Products which have similar circuit Information common at different level.
    • Common Product is a combination of products which share some common circuit information.
    • Products which share some common circuit information and combine together form a common product, are called component product.
    • Advantages of CUP System
    • Number of EFU’s can be reduced and production quantity for each lot can be increased.
    • The setup time (Changeover Time) will be reduced.
    • C&C production efficiency will be better.

  • 19. Stock Taking Sub System
    • This subsystem can support the stocktaking job for C&C area.
    • Prints the stocktaking check sheet.
    • Staffs for stocktaking fill this check sheet with circuit or material quantity in C&C area.
    • There are 4 method for filling the check sheet.
      • Circuit Group and quantity
      • Circuit and quantity
      • EFU Serial No and quantity
      • Circuit and material quantity
  • 20. GBG Subsystem
    • Unnecessary data that it passed through the specified term is exported to text file and compress. After this, these data is deleted from C&C database.
