In this paper, we study the problems about fuzzy degrees of fuzzy n - cell numbers, which can be used in ranking uncertain multi-channel digital signal information. Firstly, we introduce concepts of vector-valued fuzzy degrees and weight (number-valued) fuzzy degrees of fuzzy n - cell numbers, and then investigate their properties. At last, in order to be conveniently used in applications, we give...
We know that ranking fuzzy numbers plays an important role in decision-making and some other fuzzy application areas. In this paper, a new definition on mean of fuzzy number---quasi-mean is given. Based on the quasi-means and fuzzy degree we propose a new method for ranking fuzzy numbers. This method has the characteristics of generality, less calculation, high efficiency and it is especially tailed...
In this paper, we introduce the concept of pyramid fuzzy numbers, which may be conveniently used in some practical applications like triangle fuzzy numbers, investigate their properties, and obtain their operations rules of addition and scalar multiplication. And then, on the pyramid fuzzy number space, we define a metric that not only holds the suitability but also convenient for getting an arithmetic...
We know that decision-making is one of very important research topics in application areas and the base of decision-making is ranking, therefore ranking fuzzy numbers is also a significant research area. In this paper, we propose a new method for ranking fuzzy numbers-endpoint method. Using this mean, the only condition we need are some special points of the fuzzy number that contains the interval...
It is known that to deep systematically study the theory in relation to general discrete fuzzy numbers always will encounter some difficulties since the metric and the difference of two general discrete fuzzy numbers cannot reasonably be defined. In this paper, we define a special sort discrete fuzzy numbers-discrete fuzzy number on a fixed set with finite support set, on which we can study the problems...
