Breakdown Maintenance
With this strategy, no regular maintenance is performed. Repairs are carried out only when equipment actually fails. This approach can be risky, as it may lead to unexpected operational interruptions, but it is sometimes applied to less critical systems.
AKZ
The plant designation system AKZ is a predecessor system for identifying plants, systems, sub-systems, and equipment items for plant operating companies. The implementation of AKZ is formalized by commonly known regulations. The AKZ system is now no longer developed and maintained as a designation system.
