This paper concerns fuzzy relations with thresholds and some applications. Firstly, we consider fuzzy relations with thresholds-relation arising from many problems of real-world life, then the extension of some fuzzy inference methods using t-norms with thresholds are discussed and some calculations in SQL query forms are considered.
