  • A combined fuzzy AHP-goal programming approach to assembly-line selection 

    Authors:Ayaǧ, Zeki; Özdemir, Rıfat Gürcan
    Publisher and Date:(IOS Press, 2007)
    In mass production assembly-line balancing (ALB) problem has been a critical and repetitive issue for companies for long time. On the other hand equipment selection for stations has also been another important problem at the design stage of an assembly-line system. In this paper both problems are handled simultaneously. Therefore first goal programming (GP) method a well-suited technique is used to develop a preemptive formulation to joint both of the problems when the nature of the problem consists ...

  • A fuzzy AHP-PROMETHEE II approach for evaluation of solar power plant location alternatives in Turkey 

    Authors:Samanlıoğlu, Funda; Ayaǧ, Zeki
    Publisher and Date:(IOS Press, 2017)
    Solar energy produced through a solar power plant is a freely available non-polluting renewable source of energy that reduces the greenhouse effect. Selecting the best location for a solar power plant among several location alternatives is a complicated multiple criteria decision making (MCDM) problem since several potentially conflicting quantitative and qualitative criteria needs to be taken into consideration. In this paper of the most commonly used MCDM methods in literature

  • Add to Marked List 36 of 36 An intelligent approach for the evaluation of innovation projects 

    Authors:Samanlıoğlu, Funda; Ayaǧ, Zeki
    Publisher and Date:(IOS Press, 2020)
    In this study, an intelligent approach is presented for the evaluation and selection of innovation projects. Selecting the best innovation project is a complicated multiple criteria decision making (MCDM) problem with several potentially competing quantitative and qualitative criteria. In this paper, two hesitant fuzzy MCDM methods; hesitant fuzzy Analytic Hierarchy Process (hesitant F-AHP) and hesitant fuzzy VIsekriterijumska optimizacija i KOmpromisno Resenje (hesitant F-VIKOR) are integrated ...

  • Analysis of the Patients and Physicians Connection Network on an online Health Information Platform 

    Authors:Aydın, Mehmet Nafiz; Perdahci, N. Ziya
    Publisher and Date:(IOS Press, 2014)
    Social network applications have gained popularity in the health domain as they bring health information seekers (patients and alike) and medication advice providers (physicians and other relevant actors) together. By employing a network science perspective this research is aimed to understand an information network establishing connections among and between information seekers and providers. We found that such a connection network surfaces most of the essential characteristics of a typical complex ...

  • Examination of Centrality in a Health Social Network 

    Growing importance of health information platforms are acknowledges in recent studies. Such platforms are subject to discussion about an extent to which social network characteristics are realized. The platform under examination indeed demonstrates social network peculiarities. In this work we explore the nature of centrality in one of the leading health information networks in Europe. Among other findings we identify two nodes (representing patient and physician) are as the most important people ...

  • A fuzzy AHP-VIKOR approach for evaluation of educational use simulation software packages 

    Authors:Samanlıoğlu, Funda; Ayağ, Zeki
    Publisher and Date:(IOS Press, 2019)
    In this study, an intelligent, integrated approach is presented to help educators select the best simulation software package. Selecting the best simulation software package for educational use is a complex multiple criteria decision making (MCDM) problem with several potentially conflicting quantitative and qualitative criteria. In this paper, two fuzzy MCDM methods; fuzzy Analytic Hierarchy Process (F-AHP) and fuzzy VIsekriterijumska optimizacija i KOmpromisno Resenje (F-VIKOR) are integrated ...
