    Classification of non-pharmaceutical anti-COVID ınterventions based on novel FTOPSIS-sort models
    (Springer Science and Business Media Deutschland GmbH, 2022) Radaev, Alexander; Haktanır, Elif; Yatsalo, Boris; Kahraman, Cengiz
    Assigning alternatives to predefined ordered categories under multicriteria conditions is the essence of multi-criteria sorting problematic. The family of fuzzy multi-criteria sorting models with the common name FTOPSIS-Sort are introduced based on the fuzzy extension of Multi-Criteria Decision Analysis (MCDA) ordinary method TOPSIS with the use of different approaches to assess functions of fuzzy numbers and different fuzzy ranking methods. The features of adjusting Fuzzy TOPSIS (FTOPSIS) models to sorting problematic are presented. The developed FTOPSIS-Sort models are implemented for multi-criteria sorting of non-pharmaceutical interventions against COVID-19.

    Fuzzy multi-criteria sorting models FMAVT-Sort and FTOPSIS-Sort: features and application within the case studies
    (Springer Science and Business Media Deutschland, 2023) Radaev, Alexander; Haktanır, Elif; Yatsalo, Boris; Kahraman, Cengiz
    The need to sort alternatives according to ordered categories, especially in problems consisting of a large number of alternatives, makes it effective to use of multi-criteria sorting methods. A family of fuzzy multi-criteria sorting models FMAVT-Sort and FTOPSIS-Sort based on a fuzzy extension of MAVT and TOPSIS methods respectively and the their features are presented. In the developed models, different approaches can be used both for calculating functions of fuzzy numbers and for ranking of fuzzy numbers. Case studies showing the application of the developed models to sort problems related to the Internet of Things and anti-COVID measures are presented.
