We propose a new measure of fuzzy equality comparison based on the similarity of possibility distributions. we define a fuzzy equi–join based on the new fuzzy equality comparison, and allow threshold values to be associated with predicates of the join condition. A sort–merge join algorithm based on a partial order of intervals is used to evaluate the fuzzy equi-join. In order for the evaluation...

We introduce a non-cooperative game model in which players’ decision nodes are partially ordered by dependence relation, directly captures informational dependencies the game. In saying that node v is dependent on v1,…,vk, we mean information available to strategy making choice at precisely choices were made v1,…,vk. Although partial order games no more expressive than extensive form of imperfe...

In this paper, based on a partial order, we study the characterizations of directional derivatives and the subdifferential of fuzzy function. At the same time, we also discuss the relation between the directional derivative and the subdifferential.

We consider multiple agent settings where each agent reports a partial preference order. We derive a condition, called the TSinterval order property, on the underlying fuzzy weak preference relation which, when satisfied, yields an interval order on the set of alternatives. We then propose a greedy algorithm to aggregate those interval orders.

In this paper, we propose a new method for solving fuzzy partial differential equation using fuzzy Sumudu transform. First, we provide fundamental results of fuzzy Sumudu transform for fuzzy partial derivatives and later use them to construct the solution of fuzzy partial differential equations. Finally, we demonstrate an example to show the capability of the proposed method and present the res...

The integration of association rules and correlation rules with fuzzy logic can produce more abstract and flexible patterns for many real life problems, since many quantitative features in real world, especially surveying the frequency of plant association in any region is fuzzy in nature. This paper presents a modification of a previously reported algorithm for mining fuzzy association and cor...

in this paper, a fuzzy version of the analytic form of hahn-banachextension theorem is given. as application, the hahn-banach theorem for$r$-fuzzy bounded linear functionals on $r$-fuzzy normedlinear spaces is obtained.

The correlated demand caused by cross-selling, Zhang et al (2011) proposed a two-item EOQ model, where the unmet demand for the major item can be partially backordered with lost sales that will reduce demand for the minor item. They developed an enumeration algorithm that can deal with only one minor associated item. Zhang et al (2011) proposed the partial backordering EOQ with correlated deman...
