The first is connected with some methods of construction of such operations. Here we describe decomposable operations (e.g. t-representable t-norms) and their generalizations. Moreover we describe which properties of components are transferred to the decomposable operations. The same problem is considered for the generalization of decomposable operations. The second aspect considered in this paper is connected with algebraic properties of binary operations, i.e. for a given properties (associativity, monotonicity, commutativity and existence of neutral or zero element) we tray describe the structure of operations. In particular, we describe the structure of uninorms and nullnorms on LI .}, type={Text}, title={New trends in fuzzy sets, intuitionistic fuzzy sets, generalized nets and related topics.
