從 1988年到現在的研究，採取了巨大的進步，這本書不僅詳細介紹在這些領域的理論的進步，但認為廣泛的應用各種模糊集和模糊邏輯以及。模糊集理論和模糊邏輯理論的方方面面都涵蓋在文本的第一部分，包括：基本類型的模糊集，模糊集和清晰的集之間的連接 各種聚合操作的模糊集，模糊數和模糊數算術運算模糊關係和模糊關係方程的研究。第二部分是專門模糊集理論和模糊邏輯的應用，包括：各種方法構造模糊集的隸屬函數 使用近似推理專家系統，模糊邏輯 模糊系統和控制器，模糊數據庫 模糊決策 和工程應用。在介紹了模糊集理論和模糊邏輯感興趣的人。-Reflecting the tremendous advances that have taken place in the study of fuzzy set theory and fuzzy logic from 1988 to the present, this book not only details the theoretical advances in these areas, but considers a broad variety of applications of fuzzy sets and fuzzy logic as well. Theoretical aspects of fuzzy set theory and fuzzy logic are covered in Part I of the text, including: basic types of fuzzy sets　connections between fuzzy sets and crisp sets　the various aggregation operations of fuzzy sets　fuzzy numbers and arithmetic operations on fuzzy numbers　fuzzy relations and the study of fuzzy relation equations. Part II is devoted to applications of fuzzy set theory and fuzzy logic, including: various methods for constructing membership functions of fuzzy sets　the use of fuzzy logic for approximate reasoning in expert systems　fuzzy systems and controllers　fuzzy databases　fuzzy decision making　and engineering applications. For everyone interested in an introduction to fuzzy
