The maintenance activity isn’t a purpose in itself, it’s a necessity of which “the production
suffers” and the financial agent “considers too expensive”. It often exists a conflict between
the production units and the maintenance department, not only for a short term, but,
sometimes, for a long term, imposing a rigorous definition of each person’s responsibilities.
Considering the mutations in the industrial equipments’ technical complexity and the
accidental failures’ catastrophic consequences from the economic and/or social point of view,
it should be assigned a new dimension to the maintenance activity. One of the imperatives
imposed to this action is represented by modern means of informing through the
maintenance’s operational computerization.
