Crop Cycle Planning at 17% sanitation and changeover allowance: a worked example

Push sanitation and changeover allowance up to 17% and the picture changes. This example computes every intermediate figure at that operating point. Use it when laying out next month's sow plan, sizing how long propagation will tie up the seed line, or checking whether a new cultivar's longer cycle still fits the rack rotation.

The inputs for this scenario

  • Planned trays to seed or transplant: 480 trays (unchanged)
  • Seed line throughput: 60 trays / hour (unchanged)
  • Sanitation and changeover allowance: 17 % (raised for this scenario; the documented default is 15)

Working through the calculation

  • Applying the documented formula (Base seeding/transplant time = planned trays to seed or transplant รท seed line throughput) to the inputs above produces each figure below.
  • At this operating point the engine returns 9.36 days for required propagation time, the number this scenario is built around.
  • At this operating point the engine returns 8 days for base seeding/transplant time.
  • At this operating point the engine returns 17 % for sanitation and changeover allowance.
  • At this operating point the engine returns 60 pieces / min for seed line throughput.

How this compares with the baseline

  • Against the tool's baseline example, where sanitation and changeover allowance sits at 15% and the headline result is 9.2 days, this scenario comes in 1.74% above the baseline at 9.36 days.
  • It computes required propagation time by taking the base seeding time from trays and throughput, then inflating it for a sanitation and changeover allowance. 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

  • Required propagation time: 9.36 days (headline result)
  • Base seeding/transplant time: 8 days
  • Sanitation and changeover allowance: 17 %
  • Seed line throughput: 60 pieces / min
