Based on the concept of pseudocomplement, we introduce a new representation of preopenness of -fuzzy sets in -fuzzy bitopological spaces. The concepts of pairwise -fuzzy precontinuous and pairwise -fuzzy preirresolute functions are extended and discussed based on the --preopen gradation. Further, we follow up with a study of pairwise -fuzzy precompactness in -fuzzy bitopological spaces of an -fuzzy set. We find that our paper offers more general results since -fuzzy bitopology is a generalization of -bitopology, -bitopology, and -fuzzy topology.
