A routing total explains where time is recorded. Changing a queue assumption creates a scenario to review; it does not promise that the factory will achieve the shorter lead time.

24 QUEUE + 2 SETUP + 6 RUN + 1 MOVE + 7 WAIT40.00 hours
40 hours equals 5 working days at 8 hours/day. Halving queue reduces the arithmetic scenario to 28 hours.

Keep the source values in view
Working-day equivalent divides by scheduled hours per day. The run-time share is run divided by total; when all times are zero its percentage is unavailable. The queue scenario reduces only the entered queue component.
03
Use the output in your workflow
Use the reorder point calculator with the complete replenishment lead time, including procurement and delivery where relevant. Use the economic production quantity calculator separately to model lot sizing; a routing duration alone does not determine the economic lot.

This excludes procurement, external shipping, parallel-routing scheduling and calendars. Scheduled-day conversion does not predict delivery dates or automatically remove bottlenecks.
