AbstractThe most popular approach to handle the challenge of solving fuzzy linear programming problems is to convert the fuzzy linear programming into the corresponding deterministic linear programming. Mahdavi-Amiri and Nasseri [15, 16] developed the fuzzy dual simplex algorithm to fuzzy linear...
AbstractThe comprehensive model with “weighted-objective nearness degree” is introduced in the process of multi-objective decision-making, by which a reduction problem of inference antecedents is studied in traditional fuzzy inference method. Moreover, based on the comprehensive model with...
AbstractIn this paper, we introduce the concepts of SSP-Urysohn space, strongly SSP-Urysohn space, relatively SSP-Urysohn space and relatively strongly SSP-Urysohn space in L-topological spaces, and establish some of their fundamental properties, where L is a fuzzy lattice.
AbstractGenetic algorithm (GA) and singular value decomposition (SVD) are deployed for the optimal design of both Gaussian membership functions of antecedents and the vector of linear coefficients of consequents, respectively, of adaptive neuro-fuzzy inference systems (ANFIS) networks that are...
AbstractThe existing support vector machines (SVMs) are all assumed that all the features of training samples have equal contributions to construct the optimal separating hyperplane. However, for a certain real-world data set, some features of it may possess more relevances to the classification...
AbstractIn this paper, the ωθ -convergence theory of molecular nets in Lω-spaces is introduced. Some properties of the ωθ-convergence theory are discussed, and by means of the ωθ- convergence theory, some important characterizations of the weakly (ω1, ω2) continuous functions in Lω-spaces are...
AbstractThis paper investigates general fuzzy linear systems of the form Ax = y and general dual fuzzy linear systems of the form Ax + y = Bx + z with A, B matrices of crisp coefficients and x, y fuzzy number vectors. The aim of this paper is twofold. First, by the unique least Euclidean norm...
AbstractAs the rapid development of economy and society in the world, the situation of ecological security has become more and more severe. The problem on ecological ecurity is concerned with whether the continuous development of economy and society can realize or not, as well as the regional...
