摘要：
In this paper, a concept generalized three-way concept lattices with respect to double formal contexts is introduced to support the idea of three-way decisions. The generalized three-way operators are defined, and their properties are studied. Based on these operators, two types of generalized three-way concept lattices are constructed. The generalized three-way concept lattices provide a more general model than Wille's concept lattices and Qi-Wei-Yao's three-way concept lattices.
