Can the station rate be zero?

Yes. The margin becomes the negative required rate and coverage becomes zero.

Does positive margin prove the line can run?

No. Other stations, transfers and buffers can still constrain output. This comparison covers only the entered station.

A positive requirement makes coverage meaningful. A zero-demand scheduling question does not need this capacity comparison.

Use the same basis for both. If the station rate excludes downtime, translate the requirement to the corresponding running-time basis.

Check whether a station rate covers the entered line requirement. Enter both rates in cases per minute on the same operating basis.

Compare one packaging station running rate with the required rate on the same time basis.

Best suited to station capacity check, required rate sensitivity.
One station comparison does not locate the bottleneck across a line. Does not model buffers, blocking, starvation or product mix.

The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The producer price index for paper (not a paperboard or container index) stands at 282.266 (BLS, Aug 2026), up 10% from a year earlier. Quotes priced off last quarter's material cost miss this move.

Can the station rate be zero? Yes. The margin becomes the negative required rate and coverage becomes zero.
Does positive margin prove the line can run? No. Other stations, transfers and buffers can still constrain output. This comparison covers only the entered station.
Why must the required rate be positive? A positive requirement makes coverage meaningful. A zero-demand scheduling question does not need this capacity comparison.
Should the rates include downtime? Use the same basis for both. If the station rate excludes downtime, translate the requirement to the corresponding running-time basis.
