Formula

Old output = Math.floor(Math.max(0,v.shift_minutes-v.changeovers*v.old_setup)/v.cycle) ; New output = Math.floor(Math.max(0,v.shift_minutes-v.changeovers*v.new_setup)/v.cycle) ; Extra units = Math.floor(Math.max(0,v.shift_minutes-v.changeovers*v.new_setup)/v.cycle)-Math.floor(Math.max(0,v.shift_minutes-v.changeovers*v.old_setup)/v.cycle)

Worked example

Inputs

Shift minutes: 480 minutes
Changeovers: 4 items
Old setup: 30 minutes
New setup: 15 minutes
Cycle: 2 minutes/item

Expected results

Old output: 180 items
New output: 210 items
Extra units: 30 items

How to use this tool

Enter your own assumptions using a consistent currency and period.
Review the scenario outputs and compare alternative inputs.
Check the stated model limits before using the result in an operating plan.

Try this example

{
  "shift_minutes": 480,
  "changeovers": 4,
  "old_setup": 30,
  "new_setup": 15,
  "cycle": 2
}

Accuracy and scope

Deterministic planning scenario; inputs are assumptions, not forecasts. Excludes taxes, financing, legal requirements and costs not explicitly entered. Source explains the underlying planning framework; this specific scenario arithmetic is original.
