A class of interval-valued OWA operators can be constructed from overlap functions with weights, which plays an important role in solving multi-attribute decision making (MADM) problems considering interval numbers as attribute values. Among them, when the importance multiple attributes is different, it only calculated by changing weights. In fact, we directly abandon commutativity and extend (...

In Gal and Hanne [Eur. J. Oper. Res. 119 (1999) 373] the problem of using several methods to solve a multiple criteria decision making (MCDM) problem with linear objective functions after dropping nonessential objectives is analyzed. It turned out that the solution does not need be the same when using various methods for solving the system containing the nonessential objectives or not. In this ...

Selection of an appropriate Multiple Attribute Decision Making (MADM) method for providing a solution to given MADM problem is always challenging endeavour. The challenge even greater situations where specific there exist multiple methods with similar degree suitability. Technique Order Preference by Similarity Ideal Solution (TOPSIS) and its dominant variant the Modified TOPSIS are two very ap...

In this paper, an interval-valued Pythagorean triangular fuzzy number (IVPTFN) as a useful tool to handle decision-making problems with vague quantities is defined. Then, their operational laws are developed. By introducing a novel method of making a decision on the concept of possibility theory, a multi-attribute group decision-making (MAGDM) problem is considered, in which the attribute value...

Employee rankings can be done for various needs, one of which relates to year-end bonuses. So far, the awarding bonuses research objects has only relied on criterion, namely targets and achievements. In fact, there are many other indicators that assessed, such as attendance, discipline, communication style, cooperation, initiative. This study aims provide an alternative computation-based employ...

The intuitionistic hesitant fuzzy set (IHFS) is an enriched version of sets (HFSs) that can cover both (FSs) and (IFSs). By assigning membership non-membership grades as subsets [0, 1], the IHFS model handle situations more proficiently. Another related theory pair analysis (SPA), which considers certainties uncertainties a cohesive system represents them from three aspects: identity, discrepan...
