8. ERP and MRP MRP (material requirements planning) was the precursor to ERP MRP (material requirements planning) was the precursor to ERP Primarily a production planning and control system Primarily a production planning and control system MRP evolved to MRP II (manufacturing resource planning) MRP evolved to MRP II (manufacturing resource planning) ERP and ERP II continue to extend the links through all business processes ERP and ERP II continue to extend the links through all business processes

9. Material Requirements Planning Computerized inventory control & production planning system Computerized inventory control & production planning system Schedules component items when they are needed - no earlier and no later Schedules component items when they are needed - no earlier and no later

10. When to Use MRP Dependent and discrete items Dependent and discrete items Complex products Complex products Job shop production Job shop production Assemble-to-order environments Assemble-to-order environments

11. Material Requirements Planning Material requirements planning Planned order releases Work orders Purchase orders Rescheduling notices Item master file Product structure file Master production schedule

12. Master Production Schedule Drives MRP process with a schedule of finished products Drives MRP process with a schedule of finished products Quantities represent production not demand Quantities represent production not demand Quantities may consist of a combination of customer orders & demand forecasts Quantities may consist of a combination of customer orders & demand forecasts Quantities represent what needs to be produced, not what can be produced Quantities represent what needs to be produced, not what can be produced

13. Basic MRP Processes 1.Exploding the bill of material 2.Netting out inventory 3.Lot sizing 4.Time-phasing requirements

14. MRP Outputs Planned orders Planned orders Work orders Work orders Purchase orders Purchase orders Changes to previous plans or existing schedules Changes to previous plans or existing schedules Action notices Action notices Rescheduling notices Rescheduling notices

15. Capacity Requirements Planning (CRP) Computerized system that projects load from material plan Computerized system that projects load from material plan Creates load profile Creates load profile Identifies underloads and overloads Identifies underloads and overloads

16. Capacity Terms Load profile Load profile Compares released and planned orders with work center capacity Compares released and planned orders with work center capacity Capacity Capacity Productive capability; includes utilization and efficiency Productive capability; includes utilization and efficiency Utilization Utilization % of available working time spent working % of available working time spent working

17. More Capacity Terms Efficiency – how well the machine or worker performs compared to a standard output Efficiency – how well the machine or worker performs compared to a standard output Load Load The standard hours of work assigned to a facility The standard hours of work assigned to a facility Load percent Load percent The ratio of load to capacity Load % = (load/capacity)x100% The ratio of load to capacity Load % = (load/capacity)x100%

18. Capacity Requirements Planning MRP planned order releases Routing file Capacity requirements planning Open orders file Load profile for each machine center

Loading Allocate work to machines (resources) Allocate work to machines (resources) Perform work on most efficient resources Perform work on most efficient resources Use assignment method of linear programming to determine allocation Use assignment method of linear programming to determine allocation

30. Sequencing Prioritize jobs assigned to a resource Prioritize jobs assigned to a resource If no order specified use first-come first-served (FCFS) If no order specified use first-come first-served (FCFS) Many other sequencing rules exist Many other sequencing rules exist Each attempts to achieve to an objective Each attempts to achieve to an objective

31. Sequencing Rules FCFS - first-come, first-served FCFS - first-come, first-served LCFS - last come, first served LCFS - last come, first served DDATE - earliest due date DDATE - earliest due date CUSTPR - highest customer priority CUSTPR - highest customer priority SETUP - similar required setups SETUP - similar required setups SLACK - smallest slack SLACK - smallest slack CR - critical ratio CR - critical ratio SPT - shortest processing time SPT - shortest processing time LPT - longest processing time LPT - longest processing time

32. Critical Ratio Rule CR considers both time and work remaining CR = = If CR > 1, job ahead of schedule If CR < 1, job behind schedule If CR = 1, job on schedule time remainingdue date - today’s date work remainingremaining processing time Ties scheduling to Gantt Chart or PERT/CPM and project crashing
