One of the examples presenting the system is based on an intelligent data base and
artificial neural networks system of approximate technical diagnosis of engineering
objects (bridges)(Lefik 1994). Based on input signals which take into account among
others, a type of construction, its age, estimated degree of degradation of construction
elements and technical equipment, the system qualifies an object to specific activities
(current overhaul, major overhaul, a close-down). The system takes only into account
technical factors, however, it should be remembered that they do not exclusively decide
about a certain activity. Another example of a system supporting the activities in
technical maintenance is
industrial flooring(Gajzler 2010;Gajzler 2008).
