Maintenance optimization belongs inside capacity planning—not beside it
Separate maintenance and production models create competing versions of capacity and late operational conflicts.
Maintenance optimization and production planning often use separate models, separate calendars and separate owners. That creates multiple versions of capacity.
Operational implication
A production plan may reserve equipment that maintenance has already removed from service. A maintenance plan may protect asset reliability while creating an avoidable service or inventory impact.
Decision architecture
The planning process needs one approved capacity model that reflects maintenance windows, asset constraints, production priorities and effective dates.
Data requirements
Downtime, asset status, maintenance duration, sequence dependencies and recovery assumptions must be current and traceable.
Governance implication
Operations, maintenance and Supply Chain need explicit ownership of shared constraints and a controlled process for overrides.
Practical recommendation
Specialist optimization engines can remain where they add value. Approved downtime and asset constraints should be integrated into the authoritative Capacity Planning model used by APS and ERP.
Maintenance is not a side calendar. It is part of available capacity.
