Abstract :
The inherent feature of real-world data is uncertainty.
If data is generated in valid experiments or standard collections,
probability theory or fuzzy theory is a powerful tool for analyz-
ing them. But data is not always reliable, especially when it is
not possible to perform a reliable test or data collection multiple
times. In this situations, referring to the beliefs of experts in the
field in question is an alternative approach and uncertainty theory
is a tool by which the beliefs of experts can be mathematically in-
corporated into the problem-solving structure. In this paper, we
investigate the finding minimum weighted maximal matching with
uncertain weights. For this purpose, we offer two methods. In the
first method, by introducing the concept of chance constraint, we
obtain model with definite coefficients. The second method is based
on the concept of uncertain expected value. Finally, a numerical
example for these two methods is presented.
