  • 1. Production Scheduling
    -- Dick Lam
    Time present and time past
    Are both perhaps present in time future
    And time future contained in time past
  • 2. There is a long process in Sales & Marketing before we are committed to PRODUCTION
    Identify
    Propose
    Contact
    Meet
    Make Sale
  • 3. Schedule
    Master Production Schedule
    Materals Planning
    Production
    心寛室自大, 室小心乃寛
  • 4. Production – the core of a factory operation
    1. Production
    Add value to customers, needs support from every functional depts of the factory
    2. All Other Functional Depts
    Including Purchasing, Material, Engineering, Quality, HR & Admin, Finance & etc
  • 5. Time
    Workforce
    Inventory
    Production capacity cannot be stored
    Operators are not flexible actually
    Incorrect planning leads to increase in Inventory!
    Why matters?
  • 6. First thing first
    • Do the urgent thing first!
    • 7. Put down everything and just focus on ABC order
    • 8. Production Manager and supervisors should walk through the lines and ensure all people are doing ABC order.
    • 9. WE are team. We can make it!!
    Expedite the order of ABC company, now!!
  • 10. ABC order – the most urgent order!!
    1. ABC order
    All Other orders
  • 11. Caution!! XYZ is Urgent!!
    Shipped
    ABC Order shipped
    But All other orders are messy!!!
  • 12. More Equipment/Facility
    We need more capacity!!!
    More Space/People
  • 13. But there is nothing to do in production lines SOMETIMES!!!

    Scheduling – Model II (Sequential Processing)
    Scheduling – Model I (Multiple Machines for Single Job Task)
    Scheduling – Simplified Version (Single Production Line)
    Scheduling Principles
    Excel Basics
    Excel – User Defined Functions Library
    Challenge up, Support Down

  • 16. Before doing anything
  • 17. 1. Excel Basics
    Functions review
    Min, Max
    Vlookup
    Sumif, Sumifs
    Sumproduct
    Iferror
    Range Name
    Define, Create
    Dynamic Range
  • 18. 2. Excel User Defined Functions
    You can write some functions like “sum”, “sumif” with the parameters you define
    e.g. =sumxy(Cell1, Cell2)
    e.g. =factorial(Cell1)
    The file stored should be with .xlsm
    You can also package all the user defined functions into a library.
    The file stored should be with .xlam
  • 19. Developer Environment
  • 20. Library: DLSupplyChain.xlam
    The Excel library developed by Dick Lam for Supply Chain management
    It contains various functions for production scheduling model
    Be reminded to put in the same folder of your supply chain model, but you need to manually open it whenever you open any Excel files which use the functions contained
  • 21. Put it in the following folder:
    C:Program FilesMicrosoft OfficeOffice12XLSTART
    The library will open automatically whenever you start up Excel
    However, for users without this library in the above folder(particularly you distribute the file to others), they cannot see the result but “error”
  • 22. 3. Scheduling Principles
    Pull System
    First Deliver First Scheduled
    Identify Weakest Link/Critical Path and then exploit
    Identify the non-critical Path as well as the spare capacity
    Schedule the identical/similar components in continuous order
  • 23. Master Production Schedule
    For formula construction, please refer to the:
    Master Production Schedule.xlsx
  • 24. Basic Formula
    Opening + In – Out = Closing
    Opening + Production – Sold = Closing
    Production = Closing – Opening + Sold
    Closing = Summation of Units to be sold of future days covered by Target Inventory Days
  • 25.
  • 26. Using today capacity for tomorrow demand
    Future spare capacity cannot be used to cover today/yesterday unfulfilled demand
  • 27. MPS – Full Model
    The user defined function is included in the library of “DLSupplyChain.xlam”
  • 28. 4. Single Production Line
    It is scheduling of various job orders in a single production line
    Focus on the achievability of job orders
    Results:
    When to start and when to complete
    How many hours to complete including set up & set down time
    How many hours of spare capacity and how many quantity not achieved
    When to change die
  • 29. A Snapshot
  • 30. It is the core of all kinds of scheduling
    Multiple machines for single job task
    Sequential processing
  • 31. 5. Multiple Machines for Single Job Task
    For multiple job orders, says 100 within a week, which use the same kind of machinery or production lines, it is to allocate job order to related machines/production line with consideration of certain conditions (constraints) and tell the user if it can be achieved.
  • 32. Parallel Processing
  • 33. Model Highlight
    Based on the priority of the machines & expected completion date, it will assign quantities to various equivalent machines so as to meet the expected completion date.
    A line schedule is produced telling the following:
    What orders to produce over a certain period of time (week by week)
    When to switch product
    How many operators required
  • 34. A Snapshot
  • 35. 6. Sequential Processing
    For job orders which requires >1 sequential processes, or even with more together with parallel processes of pre-conditions, it is to allocate the job orders to related process and evaluate whether it can be completed on time
  • 36. Sequential Processing
  • 37. A Snapshot
  • 38. Conclusions
    3 Steps for Production Planning
    Master Production Schedule
    Materials Planning
    Production Scheduling
  • 39. Define your conditions
    Time gap between Delivery Date & Production Completion Date (Target Inventory Weeks)
    Identify the capacity flexibility
    Identify the weakest link
