The locus of value creation and innovation in the software industry is shifting more and more to platform ecosystems on which numerous developers create extensions with additional functionalities based on the platforms core architecture. While such complementors may strongly profit from platforms, there are considerable costs. Recent studies therefore examined the costs of fitting apps to the s...

Through this paper we advance insights regarding common patterns among information and communication technology (ICT) architectures (ICTA) found in United States’ public safety networks (PSNs). A PSN is an inter-organizational collaboration enabled by ICT to support information sharing and interoperability needs of police and associated public safety organizations. Substantial evidence makes cl...

Abstract—In the last decades, concerns about the environmental issues lead to professional and academic efforts on green supplier selection problems. In this sake, one of the main issues in evaluating the green supplier selection problems, which could increase the uncertainty, is the preferences of the experts' judgments about the candidate green suppliers. Therefore, preparing an expert system...

Recently, a new model based on Pythagorean fuzzy set (PFS) has been presented to manage the uncertainty in real-world decision-making problems. PFS has much stronger ability than intuitionistic fuzzy set to model such uncertainty. In this paper, we define some novel operational laws of PFSs and discuss their desirable properties. For the multicriteria decision-making problems with PFSs, we prop...

In this paper, we investigate a new method to handle multiple attribute group decision making (MAGDM) problems based on combined ranking value under interval type-2 fuzzy environment, in which all the attribute values provided by experts take the form of interval type-2 fuzzy sets (IT2FSs). We first introduce some basic concepts and related operational laws on IT2FSs. Then, we put forward three...

most theories in social sciences have aspects of causality, but understanding the causes of social phenomena is not possible through statistical correlation tests. to overcome this problem, fuzzy qualitative comparative analysis was developed to identify the cause of social phenomena. having qualitative roots, this method tests the necessary and sufficient causes for the emergence of a social p...

Triangular intuitionistic fuzzy number (TIFN) is a more generalized platform for expressing imprecise, incomplete, and inconsistent information when solving multi-criteria decision-making problems, as well as for expressing and reflecting the evaluation information in several dimensions. In this paper, the TIFN has been applied for solving multi-criteria decision-making (MCDM) problems, first, ...

Performance measurement in the health-care sector is a challenging task due to the wide variety in performance metrics and their interpretation. It is essential to develop a robust methodology to evaluate health-care performance since substantial and increasing amount of public resources are dedicated to health-care. With this goal in mind, this paper proposes a fuzzy decision making framework ...

Bu çalışmada, OECD ile ilişkili ülkelerin NEET durumları ekonomik ve sosyokültürel değişkenlerin birlikteliğiyle ele alınmış bulanık küme nitel karşılaştırmalı analiz (fsQCA) yöntemi incelenmiştir. Çalışmada, raporlar, endeksler veri bankalarından alınan ikincil veriler kullanılmıştır. Çalışmadaki tüm konfigürasyonlar değerlendirildiğinde, gelişmişlik düzeyi düşük/yüksek olmasına rağmen liberal...
