Order growth alone does not determine container need. Empty returns and wash queues can extend the cycle.

Measure peak flow

Use dispatch, return, washing and maintenance data from a prior peak.

Capacity card

  • Daily dispatch
  • Peak cycle
  • Wash capacity
  • Ready-container gap

Track ready quantity separately from the total pool and record scenario assumptions.

If returns are the constraint, extra units can increase idle stock.

Peak planning must include collection and preparation flow.
