It is useful to process information expressed by linguistic terms under uncertain environment. This paper proposes a layered reasoning algorithm of the linguistic truth-valued intuitionistic fuzzy lattice. Based on linguistic truth-valued intuitionistic fuzzy algebra (LTV-IFA), some concepts and properties of a new intuitionistic fuzzy layered aggregation (IFLA) operator and its inverse operator are...
Code equivalence is a basic concept in coding theory. The well-known theorem by MacWilliams gives a sufficient condition for code equivalence. Recently the MacWilliams theorem has been generalized, by Fan, Liu and Puig, making use of the generalized Hamming weights (GHWs). In this paper, we will present a further generalization of the MacWilliams theorem. Our result extends both the MacWilliams theorem...
