In
the paper shown the calculations of
technical state of structure are based on
visual assessments of the expert
during the inspection process the problem
formulated. Assessment of
technical states of already civil existing structures
are ones of the most important issues in engineering activities. Information
about the effort state of a structural member is often obtained on the basis of
a visual evaluation or specialist’s experiences. More frequently, in giving an
opinion a verbal form is used. Such a
linguistic qualification is defined as a
qualitative valuation. In a decision problem, involved in expert computer codes
for instance, linguistic information has to be expressed in terms of numerical
data. Theory of fuzzy sets enables one to processing that linguistic
information in order to make a decision that should be taken in complicated
situations.
