Analytic network process with neutrosophic sets
(Springer Verlag, 2019) Otay,İ.; Kahraman,C.
Analytic network Process (ANP) can model the inner and outer dependencies and feedbacks between the decision-making elements in a network. It calculates the correct weights of criteria, and local and global priorities of alternatives in the presence of dependencies and feedbacks. Classical ANP is a multicriteria decision making method under certainty. However, it can be used under neutrosophic uncertainty. This chapter develops a neutrosophic fuzzy ANP method and illustrates its usage and validity through the solution of a supplier selection problem in a firm manufacturing automobile spare parts. © Springer Nature Switzerland AG 2019.

An integrated AHP & DEA methodology with neutrosophic sets
(Springer Verlag, 2019) Kahraman,C.; Otay,İ.; Öztayşi,B.; Onar,S.Ç.
As a generalization of intuitionistic fuzzy sets, neutrosophic sets have been developed to represent vague, imprecise, incomplete, and inconsistent information existing in real world. The independent components of a neutrosophic set are truth, indeterminacy, and falsity. In the literature, neutrosophic sets have been employed in the development of new extensions of multiple criteria decision making methods such as neutrosophic TOPSIS and neutrosophic VIKOR. In this chapter, a new Neutrosophic Analytic Hierarchy Process (NAHP) is proposed. Then, neutrosophic AHP is integrated with neutrosophic Data Envelopment Analysis (DEA) for bringing solution to the performance measurement problems. The inputs and outputs of DEA method are weighted by Neutrosophic AHP. The proposed methodology is implemented to solve performance evaluation problem of private universities. © Springer Nature Switzerland AG 2019.

Solar PV power plant location selection using a Z-fuzzy number based AHP
(Creative Decisions Foundation, 2018) Otay,I.; Kahraman,C.
One of the most used renewable energy systems to produce clean and sustainable energy are solar energy photovoltaic (PV) plants. The selection among solar energy PV plant location alternatives requires a multi-criteria decision making approach with several conflicting and linguistic criteria. The assessment process is generally done in a vague and imprecise environment. Fuzzy set theory is often very beneficial for evaluating the subjective judgments of decision makers. The Analytic Hierarchy Process is the most used multi-criteria decision making method in the world because of its simplicity and efficiency. In this paper, we select a location for a solar energy PV plant using a 4-level hierarchy. We consider several criteria and sub-criteria including initial cost, maintenance cost, slope and distance to highways. A Z-fuzzy number is a relatively new concept in fuzzy set theory that enables one to circumvent the limitations of ordinary fuzzy numbers. Z-fuzzy numbers can be viewed as a combination of crisp numbers, intervals, fuzzy numbers and random numbers because of their generality. They give a better representation than ordinary fuzzy numbers. This study solves the multi-criteria solar PV power plant location selection problem with a Z-fuzzy based AHP method. To check the applicability of the method proposed here, a real-life case study from Turkey is presented and solved. © 2018 International Journal of the Analytic Hierarchy Process.

A state-of-the-art review of neutrosophic sets and theory
(Springer Verlag, 2019) Otay,İ.; Kahraman,C.
A neutrosophic set is a part of neutrosophy that studies the origin, nature, and scope of neutralities, as well as their interactions with different ideational spectra. Neutrosophic sets are relatively new extensions of intuitionistic fuzzy sets. The neutrosophic logic has been approved by many researchers in a short time. Especially, a significant acceleration in the number of publications on neutrosophic sets is observed after 2015. This chapter aims at classifying all these publications and to exhibiting the place of neutrosophic sets and logic in the literature. This is the most comprehensive and updated review on neutrosophic sets. Tabular and graphical illustrations are used to summarize the review results. © Springer Nature Switzerland AG 2019.
