Master Production Schedule Load with planned order quantity of 2,100 units: a worked example

This scenario runs the master production schedule load calculation on the strong side: planned order quantity of 2,100 units, with every other input held at its documented default. a master scheduler needs MPS load hours for a product family

The inputs for this scenario

  • Planned order quantity: 2,100 units (raised for this scenario; the documented default is 850)
  • Standard routing hours per unit: 1.6 hr / unit (unchanged)
  • Model mix or complexity factor: 1.08 x (unchanged)
  • Setup and planning multiplier: 1.12 x (unchanged)

Working through the calculation

  • Applying the documented formula (MPS load hours = planned order quantity × standard routing hours per unit × model mix factor × setup and planning multiplier) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,064 hr for master production schedule load hours, the number this scenario is built around.
  • At this operating point the engine returns 3,629 hr for mps load before setup multiplier.
  • At this operating point the engine returns 1.12 x for setup and planning multiplier.
  • At this operating point the engine returns 3,360 hr for planned quantity × standard hours.

How this compares with the baseline

  • Against the tool's baseline example, where planned order quantity sits at 850 units and the headline result is 1,645 hr, this scenario comes in 147% above the baseline at 4,064 hr.
  • Use it during rough-cut and detailed capacity planning, before you firm an MPS, to confirm the planned quantity fits available hours. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Master production schedule load hours: 4,064 hr (headline result)
