Factor spaces theory and its applications to fuzzy information processing: Two kinds of factor space canes

Factor space canes are discussed in details in this paper. First, naive thoughts of factor space canes are subscribed in order to have a clear notions about factor spaces and factor space canes. Second, melon-type factor space canes and chain-type factor space canes, two kinds of factor space canes, are introduced. Then switch factors and their growth relation are considered. At last, class partition and class concepts are studied that play important role on multifactorial fuzzy decision-making and representation of knowledge.
