Interval type-2 fuzzy set (IT2FS) offers interesting avenue to handle high order information and uncertainty in decision support system (DSS) when dealing with both extrinsic and intrinsic aspects of uncertainty. Recently, multiple attribute decision making (MADM) problems with interval type-2 fuzzy information have received increasing attentions both from researchers and practitioners. As a re...

Usability and guessability are two conflicting criteria in assessing the suitability of an image to be used as password in the recognition based graphical authentication systems (RGBSs). We present the first work in this area that uses a new approach, which effectively integrates a series of techniques in order to rank images taking into account the values obtained for each of the dimensions of...

Spectrum handover is a significant topic in the cognitive radio networks to assure an efficient data transmission in the cognitive radio user’s communications. This paper proposes a comparison between three spectrum handover models: VIKOR, SAW and MEW. Four evaluation metrics are used. These metrics are, accumulative average of failed handover, accumulative average of handover performed, accumu...

Recently, Multiple-Criteria Decision Making (MCDM) tools have increasingly been expanded to help researchers and practitioners to evaluate and select the best compromise alternatives. Among popular MCDM methods, Vlsekriterijumska Optimizacija I KOmpromisno Resenje (VIKOR) has attracted much attention to cope with complex problems with conflict factors. The current study conducted a state-of-the...

The main objective of the present study is to evaluate multicriteria group decision-making problem in risk management for technological innovation projects (TIPs) under dual-probabilistic linguistic information. suggested approach based on an enhanced dual probabilistic linguistic-vise kriterijumska optimizacija kompromisno resenje (DPL-VIKOR) technique assess TIP employing conventional VIKOR i...

Most multicriteria methods focus on ranking and selecting from a set of alternatives. These methods are usually used to compare all alternatives based on the synthesized scorings within a normalized scale with respect to the same criteria in multicriteria problems. However, the decision makers often simultaneously manage one or several alternatives/projects with conflicting and noncommensurable...

In today’s competitive global markets, selection of a potential supplier plays an important role to cut production costs as well as material costs of the company. This leads to successful survival and sustainability in a competitive marketplace. Therefore, evaluation and selection of an appropriate supplier has become an important part of supply chain management. The nature of the supplier sele...
