Preventive Maintenance Capacity Impact Calculator

Estimate planned PM hours, the portion that overlaps scheduled production time, capacity displaced within that schedule, and remaining scheduled hours for one period. PM hours = whole events × hours/event; capacity-displacing PM hours = min(PM hours, scheduled production hours); displaced units = capacity-displacing hours × 60 × sustained good units/minute. PM beyond the schedule is reported separately and does not create additional lost scheduled capacity. Excludes corrective downtime and does not recommend a PM interval.

Example values are prefilled to demonstrate the calculation. Replace them with values for your product, package, equipment, and operating conditions.

Inputs

Schedule, maintenance frequency, and run rate

Range: at least 0 h

Enter total scheduled production hours in the same period and equipment scope used for PM events.

Range: at least 0 count

Enter a non-negative whole event count for the same period and equipment scope.

Range: at least 0 h/event

Enter scheduled equipment downtime hours per PM event.

Range: at least 0 units/min

Enter sustained good output per minute on the same package basis as the capacity being estimated.

PM and production-window comparison
PM fits within scheduled production hours
Capacity impact scope and limitations
Planning estimate only. It treats each planned maintenance event as production time removed from the entered schedule and uses the entered sustained good rate. It does not recommend a PM interval or model corrective downtime, parallel work, recovery output, or maintenance performed outside scheduled production.
