Hesitant Fuzzy Linguistic Arithmetic Aggregation Operators in Multiple Attribute Decision Making
2
2
In this paper, we investigate the multiple attribute decision making (MADM) problem based on the arithmetic and geometric aggregation operators with hesitant fuzzy linguistic information. Then, motivated by the idea of traditional arithmetic operation, we have developed some aggregation operators for aggregating hesitant fuzzy linguistic information: hesitant fuzzy linguistic weighted average (HFLWA) operator, hesitant fuzzy linguistic ordered weighted average (HFLOWA) operator and hesitant fuzzy linguistic hybrid average (HFLHA) operator. Furthermore, we propose the concept of the dual hesitant fuzzy linguistic set and develop some aggregation operators with dual hesitant fuzzy linguistic information. Then, we have utilized these operators to develop some approaches to solve the hesitant fuzzy linguistic multiple attribute decision making problems. Finally, a practical example is given to verify the developed approach and to demonstrate its practicality and effectiveness.

A satisfactory strategy of multiobjective two person matrix games with fuzzy payoffs
2
2
The multiobjective two person matrix game problem with fuzzy payoffs is considered in this paper. It is assumed that fuzzy payoffs are triangular fuzzy numbers. The problem is converted to several multiobjective matrix game problems with interval payoffs by using the $alpha$cuts of fuzzy payoffs. By solving these problems some $alpha$Pareto optimal strategies with some interval outcomes are obtained. An interactive algorithm is presented to obtain a satisfactory strategy of players. Validity and applicability of the method is illustrated by a practical example.

Bisimulation for BLgeneral fuzzy automata
2
2
In this note, we define bisimulation for BLgeneral fuzzy automata and show that if there is a bisimulation between two BLgeneral fuzzy automata, then they have the same behavior.For a given BLgeneral fuzzy automata, we obtain the greatest bisimulation for the BLgeneral fuzzy automata. Thereafter, if we use the greatest bisimulation, then we obtain a quotient BLgeneral fuzzy automata and this quotient is minimal, furthermore there is a morphism from the first one to its quotient.Also, for two given BLgeneral fuzzy automata we present an algorithm, which determines bisimulation between them.Finally, we present some examples to clarify these new notions.

Characterizations of $L$convex spaces
2
2
In this paper, the concepts of $L$concave structures, concave $L$interior operators and concave $L$neighborhood systems are introduced. It is shown that the category of $L$concave spaces and the category of concave $L$interior spaces are isomorphic, and they are both isomorphic to the category of concave $L$neighborhood systems whenever $L$ is a completely distributive lattice. Also, it is proved that these categories are all isomorphic to the category of $L$convex spaces whenever $L$ is a completely distributive lattice with an orderreversing involution operator.

Multiple Fuzzy Regression Model for Fuzzy InputOutput Data
2
2
A novel approach to the problem of regression modeling for fuzzy inputoutput data is introduced.In order to estimate the parameters of the model, a distance on the space of intervalvalued quantities is employed.By minimizing the sum of squared errors, a class of regression models is derived based on the intervalvalued data obtained from the $alpha$level sets of fuzzy inputoutput data.Then, by integrating the obtained parameters of the intervalvalued regression models, the optimal values of parameters for the main fuzzy regression model are estimated.Numerical examples and comparison studies are given to clarify the proposed procedure, and to show the performance of the proposed procedure with respect to some common methods.

This paper presents the concepts of $(L,M)$fuzzy Qconvergence spaces and stratified $(L,M)$fuzzy Qconvergence spaces. It is shown that the category of stratified $(L,M)$fuzzy Qconvergence spaces is a bireflective subcategory of the category of $(L,M)$fuzzy Qconvergence spaces, and the former is a Cartesianclosed topological category. Also, it is proved that the category of stratified $(L,M)$fuzzy topological spaces can be embedded in the category of stratified $(L,M)$fuzzy Qconvergence spaces as a reflective subcategory, and the former is isomorphic to the category of topological stratified $(L,M)$fuzzy Qconvergence spaces.

Fuzzy Topology Generated by Fuzzy Norm

In the current paper, consider the fuzzy normed linear space $(X,N)$ which is defined by Bag and Samanta. First, we construct a new fuzzy topology on this space and show that these spaces are Hausdorff locally convex fuzzy topological vector space. Some necessary and sufficient conditions are established to illustrate that the presented fuzzy topology is equivalent to two previously studied fuzzy topologies.

Extended Fuzzy $BCK$subalgebras

This paper extends the notion of fuzzy $BCK$subalgebras to fuzzy hyper $BCK$subalgebras and defines an extended fuzzy $BCK$subalgebras. This study considers a type of fuzzy hyper $BCK$ideals in this hyperstructure and describes the relationship between hyper $BCK$ideals and fuzzy hyper $BCK$ideals. In fact, it tries to introduce a strongly regular relation on hyper $BCK$algebras. Moreover, by using the fuzzy hyper $BCK$ideals, it defines a congruence relation on (weak commutative) hyper $BCK$algebras that under some conditions is strongly regular and the quotient of any hyper $BCK$algebra via this relation is a $($hyper $BCK$algebra$)$ $BCK$algebra.
