Combination of measurement uncertainty contributions via the generalized Dombi operator

Possibility is considered as a promising mathematical tool to represent that particular case of incomplete information given by a measurement result. A measurement result can be affected by systematic and random effects. The combination of random contributions in the possibility theory returns only approximated results, and it is important to identify an optimal combination method to obtain acceptable uncertainty evaluations. This paper considers the generalized Dombi operator as a promising tool to obtain satisfying results.
