An approach to validation of fuzzy qualitative temporal relations

A geometrical approach to validation of fuzzy temporal relations between fuzzy time primitives, based on possibility and necessity measures is proposed in the paper. Fuzzy temporal relations between fuzzy time points and a fuzzy time point and fuzzy time interval are considered. The same approach can be used for evaluation of relation between two fuzzy intervals. An example of validation temporal relations between a fuzzy time point and fuzzy time interval is given.
