Abstract
A geometrical approach to validation of fuzzy temporal relations between fuzzy time primitives, based on the possibility and necessity measures are proposed. Fuzzy temporal relations between fuzzy time points and 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 of temporal relations between a fuzzy time point and fuzzy time interval is given.

Keywords
fuzzy temporal knowledge, fuzzy temporal relations, necessity and possibility measures
