does not satisfy (EP), because for x = 0.3, y = 0.5 and z = 0.5 we get I (x, I (y, z)) = 0.7 = 0.5 = I (y, I (x, z)). The corrected last two rows are provided in Table 1 here. In both of these cases the natural negation NI is the classical negation NC(x) = 1 − x. One can easily check that the first function satisfies (I1) and it does not satisfy (EP), because for x = 0.3, y = 1 and z = 0, we ge...

In this work we solve an open problem of U.Höhle [Problem 11, Fuzzy Sets and Systems 145 (2004) 471-479]. We show that the solution gives a characterization of all conditionally cancellative t-subnorms. Further, we give an equivalence condition for a conditionally cancellativite t-subnorm to be a t-norm and hence show that conditionally cancellativite t-subnorms whose natural negations are stro...

Abstract The linguistic Pythagorean fuzzy sets (LPFSs), which employ terms to express membership and non-membership degrees, can effectively deal with decision makers’ complicated evaluation values in the process of multiple attribute group decision-making (MAGDM). To improve ability LPFSs depicting information, this paper generalized cubic (CLPFSs) studied CLPFSs-based MAGDM method. First, def...

In Suichang gold mine, the altered rock type deposits were cut by faults and joint fissures, leading to complex resource endowment characteristics, large changes in occurrence, a serious of ore vein branches great difficulty mining. order select suitable mining method for such difficult complicated orebody, multi-factor multi-index comprehensive evaluation system involving benefits, costs, safe...

in this paper, a new definition of fuzzy bounded sets and totallyfuzzy bounded sets is introduced and properties of such sets are studied. thena relation between totally fuzzy bounded sets and n-compactness is discussed.finally, a geometric characterization for fuzzy totally bounded sets in i- topologicalvector spaces is derived.

This article describes the development and psychometric evaluation of the short-form Pulmonary Functional Status Scale (PFSS-11©) derived from the previously validated 35-item PFSS, using data from 179 subjects (120 Chronic Obstructive Pulmonary Disease [COPD]/59 normative, non-COPD). Items were extracted based on item-response distribution and commonality >.60. Factor analysis yielded a three-...

The aim of this paper was to explore decision-making using Pythagorean fuzzy sets with an acronym in Portuguese for Interactive multi-criteria decision making (TODIM) approach. We propose a novel model that TODIM integrates the technique order preference by similarity ideal solution (TOPSIS) and concepts solve problems related core alternatives facing innovative companies under bullwhip effect ...
