Öğe A multi-criteria decisionıon-making model for ranking smart megacities and defing their key performance indicators(Çanakkale Onsekiz Mart Üniversitesi, 2023) Baki, RahmiThe aim of this study was to develop an integrated and innovative approach to facilitate the ranking of evaluation criteria used to assess and compare smart megacities (SMCs). The methodology used to design the approach was based on Criteria Importance through CRITIC and CODAS. In this method, the degree of importance of each item of the criteria affecting the concept of a smart city was determined by CRITIC, an objective weighting method. Then, megacities can be compared using the CODAS technique to determine the extent to which they have adopted smart city concepts. In the current study, 32 SMCs were compared in four main areas and 20 subcategories. An analysis of the order of importance given to each area found that mobility and activities (0.32) was highest, followed closely by health and safety (0.313), opportunities (0.198), and governance (0.168). The subcategories with the greatest weight were the availability of a website/application that enables citizens to easily donate surplus items (0.076), online information about traffic conditions (0.073), and online access to job opportunities (0.062). In addition, it was determined that the most successful megacities applying the smart city concept are Beijing and Hangzhou. This study has the potential to be considered a pioneer in the literature in terms of the proposed methodology for an empirical evaluation to support smart megacity planning.Öğe An integrated multi-criteria structural equation model for green supplier selection(Korean Society for Precision Engineeing, 2022) Baki, RahmiThe aims of the current study are to determine the criteria to be considered in a green supplier selection (GSS) process, develop an integrated decision-making approach using structural equation modelling (SEM) and fuzzy additive ratio assessment (ARAS) techniques to rank suitable suppliers, and investigate the effectiveness of this approach in collective decision-making. The study’s ultimate objective is to propose a method created from the perspective of fuzzy logic in which criterion weights are determined using SEM to resolve decision-making challenges such as GSS, in which a compromise solution is desired. In the first stage of the study, relevant literature as examined in detail. Eight main criteria and 27 sub-criteria were detected, taking into account classical, green, and social supplier selection (SS) criteria. A questionnaire was administered to 254 participants who were actively involved in SS processes for their companies, and the data were analyzed using SEM. In the second phase, six suppliers were evaluated considering the criteria found to have a positive impact on GSS, and fuzzy ARAS was applied. The results showed that the factors affecting GSS are quality (0.291), social responsibility (0.222), service (0.21), cost (0.149) and green product (0.128). The study presents an effective, objective, and fast method that can be used in decision-making problems such as GSS, that prevents potential loss of information and lack of transparency through an integrated approach, and that can be tested with a generalizable framework. The proposed hybrid method is an efficient and practical approach that can be tested on many decision-making problems, such as SS.Öğe An integrated, multi-criteria approach based on environmental, economic, social, and competency criteria for supplier selection(EDP Sciences, 2021) Baki, RahmiSupplier selection (SS), which is a critical stage of supply chain management (SCM), is no longer evaluated solely from the perspective of traditional criteria, due to increasing environmental problems and ethical concerns. In this study, a multidimensional approach including environmental, economic, social, and competency concepts was proposed to evaluate SS, and an integrated approach based on Best Worst Method (BWM) and fuzzy TODIM (an acronym in Portuguese of Interactive and Multi-criteria Decision Making) techniques was developed. In the developed approach, BWM was used to first obtain the importance level of the criteria and then to rank the suppliers with fuzzy TODIM. The proposed approach was tested on an automotive company in Turkey. The outcomes of the analysis revealed that the most important main criteria for SS are economic (0.377) and environmental criteria (0.290). In addition, the sub-criteria with the highest criteria weight were listed as product cost (0.120), on-time delivery (0.112), quality control (0.094), logistics costs (0.069), management commitment (0.054), and flexibility (0.054). The results of this study offer theoretical and practical outputs to companies that want to improve their SS process, selection of suppliers, and contributions of the researchers working on the topic.Öğe Analysis of factors affecting customer trust in online hotel booking website usage(CITUR Centre for Tourism Research, Development and Innovation, 2020) Baki, RahmiTourism is a rapidly growing industry world-wide, and internet technologies are becoming increasingly important in that industry. Online hotel booking website (OHBW) has become an important tool in the marketing of hotel services. In this study, the factors affecting the trust perception of OHBW users were investigated. Data collected from 456 consumers using OHBWs were analysed using structural equation modelling. The results showed that reputation, security, ease of use and risk significantly affected the user's perception of trust. In addition, the perception of trust has a positive effect on customer loyalty. As a result, this study aims to provide useful findings to OHBW managers and researchers who want to increase customer trust and ensure their loyalty.Öğe Analysis of the studies on e-learning acceptance of learners in the middle east and the proposal of an extended technology acceptance model(Kastamonu Üniversitesi, 2020) Baki, Rahmi; Birgören, BurakE-learning applications can result in various expectations, attitudes and needs based on the users’ geographical regions and cultural roots, therefore, design of e-learning systems by taking into account the individuals’ cultural and demographic attributes is crucial for an effective learning environment. This study considers 44 researches that assess users’ e-learning acceptance characteristics in 10 different Middle Eastern countries, where 45 external variables are proposed as predeterminants of Perceived Usefulness (PU) and Perceived Ease of Use (PEOU), both of which are Technology Acceptance Model’s (TAM) belief components. 75 hypotheses are tested 155 times where these external variables are presented to be the antecedents of the belief components. With the help of a region-based literature review; it is aimed to identify the factors causing users’ system acceptance in the Middle East. As a result, an extended TAM is proposed for the Middle East by incorporating the most frequently accepted hypotheses into the original TAM.Öğe Application of ROC and CODAS techniques for cloud service provider selection(Gaziantep Üniv. Sosyal Bilimler Enst., 2022) Baki, RahmiDue to the widespread use of cloud services, the choice of cloud service providers has become an important problem for companies. It is a strategic decision-making problem for companies to determine the most suitable service provider that can meet their expectations and needs. Choosing the most effective service provider for a firm depends on numerous criteria based on the firm's strategies, needs and resources. Therefore, in the present study, an integrated decision model based on Rank Order Centroid (ROC) and Combinative Distance-Based Assessment (CODAS) techniques has been developed. In the first stage of the application, the criteria were evaluated using the ROC method, and the service providers were listed using the CODAS technique in the second stage. The effectiveness of the proposed model has been tested by a software company that wants to select a cloud service provider. The results of the research are expected to contribute to service providers and firms that want to select cloud service providers that can meet their needs.Öğe Avrupa Birliği Üye ve Aday Ülkelerin Sosyo-Ekonomik Performanslarının Çok Kriterli Bir Yaklaşımla Değerlendirilmesi(nomi ve Finansal Araştırmalar Derneği, 2023) Baki, RahmiToplumun uzun vadeli çıkarlarına zarar vermeden ekonomik büyümeyi gerçekleştirme ve çevreye zarar vermeden ihtiyaçları karşılama yeteneği olarak tanımlanan sosyo-ekonomik sürdürülebilirlik (SES), birçok ülke için kritik bir gündem maddesidir.

Sosyal Bilimler Enst., 2024) Baki, RahmiBRICS countries’ recent investments in technology have attracted attention, and they have become a part of the nations that conduct research around the world. The European Innovation Scoreboard (EIS), accepted as an effective benchmarking tool for technology policies, provides a comparative analysis of the innovation performances of many countries, including BRICS. In the current research, the innovation performances of BRICS countries were compared through EIS data, one of the most adopted benchmarking tools in technology policy discussions. Thus, it was aimed to determine the importance levels of the criteria used in the EIS data and to analyze the innovation processes of the countries in question. In this study, an integrated framework using CRiteria Importance Through Intercriteria Correlation (CRITIC) and Grey Relational Analysis (GRA) methods is presented to compare the innovation performances of BRICS countries. In the first stage of the application, the importance levels of the criteria are obtained using the CRITIC method, while in the second stage, countries are ranked according to their innovation performance through GRA. Data are obtained by compiling statistics from the EIS database created by the Commission of the European Communities. The results obtained in the practical application of the model rank the criteria according to their weights as follows: higher education (0.249), international joint publications (0.176), medium and high technology exports (0.122), frequently cited publications (0.113), PCT patents (0.094), public-private joint publications (0.085), designs (0.083) and trademarks (0.078). In addition, the BRICS countries are ranked according to their innovation performance as China (0.76), Russia (0.6), South Africa (0.516), Brazil (0.426), and India (0.378).Öğe Comparison of the socio-economic sustainability performance of OECD countries(ACC Publishing, 2022) Baki, RahmiSocio-economic Sustainability (SES) enables an organisation or a country to pursue economic growth in the present without undermining the ability of future generations to meet their needs, especially in terms of curtailing the depletion or destruction of environmental resources. Ensuring SES in a country helps shape the conditions for long-term economic and social development while conserving the environment. This study compares the SES performance of 38 member countries of the Organisation for Economic Cooperation and Development (OECD) by applying a multi-criteria approach. This research aims to make inferences about SES in developed and developing countries and promote change in line with sustainable development goals. A technique known as Multi-Attributive Border Approximation area Comparison (MABAC), considered a valuable and reliable decision-making tool for rational management, was applied. In practice, socio-economic performance indicators obtained from the United Nations Development Programme (UNDP) were examined to evaluate the performance of the 38 OECD countries included based on nine criteria.Öğe Evaluating and classifying market alternatives using the CAPMA technique to assess potential export volume: an application for Turkey’s fig exports(Emerald Publishing, 2024) Baki, RahmiAppropriate target market selection and classification are complex, time-consuming, and strategically important management decisions. The current study proposes and implements a new systematic approach that evaluates and ranks alternative markets’ potential to increase the export volume of Turkey’s fig exports. Design/methodology/approach: The classification approach of potential market alternatives (CAPMA) method, which was developed to evaluate, compare, and classify alternative markets according to their potential, was used in this study. CAPMA, an objective decision-making technique, is based on calculating the classification coefficient and classifying the alternatives into four dimensions, taking this coefficient into consideration. In the current study, 25 alternative markets were analysed on the basis of four evaluation criteria and classified into four dimensions according to their potential to increase export volume. Findings: According to the application results, alternative markets with the greatest potential to increase export volume were identified as the United States of America (USA), Netherlands, China, and Spain. The USA has the greatest potential for expansion of export volume. By implementing correct and effective marketing strategies, fig export volume has the potential to reach very high levels. Originality/value: The study’s results on alternative markets for fig exports were categorized, countries with greater potential to increase export volume were identified, and findings that could contribute to the development of the sector were obtained. The approach proposed in the current research can be used to determine the target market of many other products, especially agricultural products, whose production is concentrated within a specific geography.Öğe Evaluating hotel websites through the use of fuzzy AHP and fuzzy TOPSIS(Emerald Group Holdings Ltd., 2020) Baki, RahmiPurpose: The purpose of this study is to develop a useful, effective and comprehensive approach to facilitate the evaluation of hotel websites. Design/methodology/approach: The paper examines the literature evaluating e-commerce sites, particularly that is focused on hotel, tourism and travel. Moreover, 5 criteria and 19 sub-criteria are identified, and a two-step method is proposed for the assessment of hotel websites whereby the global weights of the proposed criteria are determined by the fuzzy analytic hierarchy process, and hotel websites are ranked through the fuzzy technique for order preference by similarity to ideal situation. Findings: The results show that the leading criteria to effectively evaluate hotel websites are trust and information quality and that the most important sub-criteria are special discounts, assurance and reservation information. Practical implications: This research offers practical advice to increase understanding of the determinants of an effective hotel website so that appropriate strategies can be developed to convert a website visitor into a customer. Originality/value: The study aims to contribute to businesses operating in the tourism sector which seeks to increase the effectiveness of their websites by identifying criteria and proposing a methodology for hotel website evaluation.Öğe Extended VIKOR method based on interval-valued intuitionistic fuzzy numbers for selection of logistics centre location(Mustafa SÜLEYMAN ÖZCAN, 2022) Baki, RahmiIdentifying the appropriate location for logistics centres (LC) is key to gaining and maintaining a competitive advantage and increasing the efficiency of supply chain activities. Increasing customer expectations, efforts to reduce logistics costs and the intensity of competition in the logistics sector have led to the establishment of many new LMs in recent years. These centers contribute significantly to increasing efficiency in freight transportation, optimizing logistics services and reducing the traffic. The increasing importance of LCs and the significant impact of their location on logistics activities have made the choice of installation site a strategic consideration. However, evaluating LC location alternatives is a complex process that must take many factors into account. The aim of the present study is to propose an extended VlseKriterijuska Optimizacija I Komoromisno Resenje (VIKOR) approach based on interval-valued intuitionistic fuzzy numbers (IVIFN) and test its feasibility. Applying IVIFN contributes to coping with uncertainty in human thought and decision processes. On the other hand, VIKOR is a decision-making technique that facilitates ranking criteria that are contradictory and represented by different units, and it offers a compromise solution. The feasibility of the extended VIKOR approach through IVIFN proposed in this study was tested in a numerical example in which LC location alternatives were evaluated. Three experts were consulted to determine the criterion weights and to rank the alternatives. Decision makers serve as logistics and planning specialist, logistics operations manager and supply chain chief engineer. In practice, alternatives were evaluated by considering six criteria. As a result, criteria are listed in the form of intermodal connection (0.255), infrastructure (0.194), security/safety (0.169), proximity to customers (0.158), proximity to suppliers (0.131), and labour supply (0.093), according to their weighted importance. It is expected that the findings obtained in the study will contribute to researchers and sector managers.Öğe Harmonizing Education: Exploring Factors Affecting Acceptance of AI-Supported Mobile Apps in Music Education(FrancoAngeli, 2024) Ceviz, Berk; Baki, Rahmi...Öğe Identifying factors affecting intention to use in distance learning systems(Anadolu University / Anadolu Üniversitesi, 2021) Baki, Rahmi; Birgören, Burak; Aktepe, AdnanThe use and benefit of Distance Learning Systems (DLS) can be increased by a detailed analysis of the factors affecting students’ intention to use. This study aims to analyse the effect of various independent variables on the user satisfaction and intention to use DLS via Perceived Ease of Use and Perceived Usefulness. In addition, Time Effectiveness is proposed as a new variable with the claim that the time spent in DLS is valuable. Data were collected from 925 undergraduate students currently enrolled in 9 state universities in Turkey. Data were analysed through Structural Equation Modelling (SEM). Results show that while Interaction, Compatibility and Time Effectiveness have a positive effect on user satisfaction and intention to use via Perceived Usefulness; Self Efficacy, Subjective Norm and Enjoyment have no influence. Moreover, Self Efficacy, Interaction, Anxiety and Time Effectiveness have a significant impact on Perceived Ease of Use, yet Subjective Norm and Enjoyment don’t.Öğe Opec Üyesi Ülkelerin TOPSIS Tekniği Aracılığıyla Performans Analiz(Aksaray Üniversitesi, 2023) Altınsoy, Emre; Baki, RahmiEnerji kaynakları arasında önemli bir yere sahip olan petrol, küresel alanda kullanılmakta olan en büyük enerji kaynaklarından birisidir. Global dünyada petrol ve petrol yataklarına sahip olan devletlerin diğer devletlere karşı maddi ve de ekonomik olarak büyük oranda üstünlükleri bulunmaktadır. Bu yakıt enerjisine (petrol rezervlerine) sahip olan bazı devletlerin zaman zaman yapmış oldukları siyasi ve de politik kararlar neticesinde kendi topraklarında petrol rezervleri bulunmayan diğer devletlerin (petrol temelli politika ya da petrole bağlı kararlar nedeniyle oluşabilecek) ekonomik krizlerine neden olabilmektedir. Bu nedenden dolayı orta doğuda Iran ’ın başkentinde 1960’da OPEC adı verilen bir örgüt kurulmuştur ve şu anda toplam 12 devletten oluşmaktadır. Bu örgütün amacı kendi topraklarındaki petrol rezervleri bulunan ülkelerin, kendi ülkelerinde petrol bulunmayan ülkelere ihraç etmelerini ve oluşabilecek herhangi bir küresel krizlerin önüne geçmek amacıyla kurulmuştur. Bu örgütün temel prensibi petrol kaynaklarını ihraç eden ülkelerin üretkenliğini sağlar iken bu kaynakları ithal eden ülkelerin ise tekrar bir küresel anlamda petrol krizi yaşamamalarını önlemektir. OPEC üzerine yapılan bu çalışmada veriler 12 devlet (alternatif) ve 11 kriterden oluşmaktadır. Bu veriler, OPEC tarafından kendi resmî web sayfasında yayınlamış ve üzerlerinde çalışılmak üzere oradan alınmıştır.Öğe The evaluation of target markets for hazelnut exports with the classification approach of potential market alternatives(Emerald Publishing, 2023) Baki, RahmiThe aim of the proposed classification approach of potential market alternatives (CAPMA) is to provide exporting countries with a framework for identifying potential market opportunities for their products or services. Design/methodology/approach: In today's global market conditions, with competition increasing daily, companies, businesses and states must seek new markets at the national and international level. Target market selection is a strategic process that directly affects the success of an organization and can lead to important results in the short and long term. The process requires systematic research and digitization of data to analyse target markets. Findings: The study tested the proposed approach by analysing Turkey's potential markets for hazelnut exports and identifying new target markets. A significant part of Turkey's hazelnut exporting is confined to the European geography of Turkey, the leading country in hazelnut production and export. Twenty potential markets were evaluated on the basis of 11 criteria, and feasible alternatives were categorized into four classes. The study revealed that the USA, India, the United Kingdom and Japan were in the category of markets with the greatest potential for increasing exports (Dimension 1). Originality/value: This study has developed a novel approach that allows the comparison of the current market situation with potential market outcomes and creates an accurate classification of target markets.Öğe The factors that affect healthcare workers' intention to use of E-finance applications in Turkey(World Scientific, 2021) Baki, Rahmi; Bağcı, HaşimE-finance applications, being the significant outcome of the rapid developments in information technologies in the finance sector, have grown to be increasingly significant and beneficial.
