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