For the planning of a machine or plant, long-term costs must also be taken account. One cost factor is maintenance and upkeep of the entire plant and/or single components.
Presumably every maintenance engineer wishes to work under ideal conditions. However, that is rarely the case – no question.
Anyway, in order to compare maintenance time for machine and plant components, an ideal picture must be considered.
The fact is that the easier a machine or plant component can be maintained in an ideal case, the easier it is also under more difficult circumstances.
