Flexible Packaging Changeover at 17% adjustment and verification allowance: a worked example

Push adjustment and verification allowance up to 17% and the picture changes. This example computes every intermediate figure at that operating point. Use this when scheduling production on a flexible packaging line, estimating lost capacity from changeovers, or comparing SMED improvement scenarios to reduce changeover duration.

The inputs for this scenario

  • Number of changeover tasks: 8 tasks (unchanged)
  • Average time per task: 6 min / task (unchanged)
  • Adjustment and verification allowance: 17 % (raised for this scenario; the documented default is 15)

Working through the calculation

  • Applying the documented formula (Base changeover time = number of changeover tasks x average time per task) to the inputs above produces each figure below.
  • At this operating point the engine returns 1.56 hr for total changeover time, the number this scenario is built around.
  • At this operating point the engine returns 1.33 hr for base changeover time.
  • At this operating point the engine returns 17 % for verification and adjustment allowance.
  • At this operating point the engine returns 6 pieces / min for average task completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where adjustment and verification allowance sits at 15% and the headline result is 1.53 hr, this scenario comes in 1.74% above the baseline at 1.56 hr.
  • It computes total changeover time by summing the task time and applying a percentage allowance for adjustment and first-article verification. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total changeover time: 1.56 hr (headline result)
  • Base changeover time: 1.33 hr
  • Verification and adjustment allowance: 17 %
  • Average task completion rate: 6 pieces / min
