Today, the competitive environment is no longer just competition, but competition in supply networks. While the amount of data used in the field of the supply chain is increasing rapidly, systems that are thought to be smart and fast have started to be developed. Big data analytics covered in this study is one of the most effective resources for solving business problems. In this study, examining the effect of big data analytics on creating effective service designs is discussed. Statistical data analysis methods were used to examine the relationship between statistical analyzes, SPSS program and study variables. After examining the sociodemographic profiles of the participants, the descriptive analysis results of bda management capacity, service quality scale and sub-dimensions were examined. While examining the level differentiation of the variable groups according to the personal information of the participants, 'independent sample t-test' was used in the comparison of the variables that provided the assumption of normal distribution, and 'ANOVA' was used in the comparison of the three variables. In addition, while testing the relationship between BDA management skill, service quality scale and its sub-dimensions, 'Pearson correlation' analysis, which is one of the parametric test methods, was preferred and all results were evaluated in terms of statistical significance at the p<0.05 level. In addition, the results were obtained from the correlation analysis, and the effects between the scales were examined by regression analysis. Statistical significance was evaluated at the p<0.05 level in all the results obtained. In the demographic information section of the questionnaire used in the study, there are questions about the main sector of activity, the boundary conditions of the field of activity, the number of employees, the operating period of the company and the duration of the current job. Study variables include BDA management capacity and service quality. A 5-point Likert scale (1=strongly disagree - 5=strongly agree) was used to answer the questions used in the research questionnaire. The findings of the study were discussed, and recommendations were made. keywords: big data, effective service design, supply networks.Article Citation - WoS: 9INVESTIGATING THE KEY DRIVERS IN THE TRANSITION TO SUSTAINABLE HYDROGEN TRANSPORTATION FUEL(Dr. Viktor Koval, 2024-09-18) Muruvvet Deniz Sezer; Erhan Ada; Yigit Kazancoglu; Sezer, Muruvvet Deniz; Ada, Erhan; Kazancoglu, YigitIntroduction. .

Under these operations, maintenance activities have significant environmental, social and economic consequences for organizations; therefore, sustainable maintenance is a significant concept for organizations. Due to the nature of maintenance activities, multiple risks are associated with them. It is crucial to systematically define and evaluate these risks to achieve more sustainable practices and improved operational performance. From this perspective, this study aims to define risks associated with sustainable maintenance, evaluate them to gain a deeper understanding and provide recommendations for enhancing operational performance.Design/methodology/approachFuzzy synthetic evaluation is employed for multidimensional risk evaluation, which systematically analyses these risks using the level of severity (LS), likelihood of occurrence (LO) and detectability (D) as parameters. In total, seven main risks and 35 sub-risks are presented in this study.FindingsThe results showed that risks related to employee attitudes and managerial and organizational issues dominate sustainable maintenance, revealing the importance of the human factor in sustainable maintenance. Furthermore, all risks are ranked based on the study's findings, and implications are presented about these results.Originality/valueAlthough interest in sustainable maintenance is proliferating in the operations management field, and risks in maintenance have been studied by different authors, none of these studies have integrated risk evaluation with sustainable maintenance by providing specified risks that combine the concepts of sustainability risks and maintenance risks. The primary contribution of this study lies in combining these concepts to provide a multidimensional risk evaluation that enhances operational performance. The results of this research are expected to provide valuable insights into sustainable maintenance operations from a risk evaluation perspective, and the suggestions provided in the study will be beneficial for improving operational performance.Doctoral Thesis Barriers in Cement Industry towards Circular Economy(2024) Aydın, Uğur; Ada, Erhan; Mangla, Sachın KumarCement, serving as the primary ingredient in concrete, plays a pivotal role in industrial development and societal progress. However, its production is marked by high energy consumption, environmental pollution, and significant CO2 emissions. This study adopts the perspective to explore the challenges and barriers facing the cement industry in transitioning to a circular economy. It aims to define the causal relationships among these barriers and identify practical implications necessary to overcome them. To achieve a comprehensive understanding, the study integrates results from a systematic literature review and focus group study. The DEMATEL method is employed to elucidate the causal relations between various factors. A total of 18 barriers, organized into six clusters, have been identified. These findings are intended to inform managerial decisions and accelerate the adoption of circular economy applications in the cement business. While existing studies on circular economy in cement focus on technical and laboratory aspects related to the use of alternative materials, this study stands out by examining and revealing the barriers hindering the cement sector's transition to circular economy practices, making it a novel and unique contribution to the field. Keywords: sustainability, circular economy, cement, barriers, challengesArticle Citation - WoS: 8Citation - Scopus: 11Barriers to Cement Industry Towards Circular Economy(Ram Arti Publishers, 2023-08-01) Erhan Ada; Yigit Kazancoglu; Sachin Kumar Kumar Mangla; Ugur Aydin; Aydin, Ugur; Ada, Erhan; Kazancoglu, Yigit; Mangla, Sachin KumarCement as the main component of concrete is a crucial industrial product for economic development and civilization. Nevertheless its production is highly energy-intensive environmentally polluting and a source of extreme CO2 emissions. For success in the transition to the circular economy and accelerating sustainable manufacturing in the cement industry understanding and addressing the main barriers are essential. Using the above point of view this study intends to address the challenges and barriers of the cement industry in the transition to a circular economy define the causal relationships between these barriers and determine the necessary practical implications to overcome the barriers. Systematic literature review and focus group study results enable a holistic model that integrates research results and business practical criteria. The DEMATEL method is used for the clarification of causal relations between factors. A total of 18 barriers in 6 clusters have been revealed to be used for managerial implications to speed up the transition to CE applications in the cement business. Out of 18 barriers 6 were effect groups which were the outcomes due to the remaining 12 causing barriers. The top three cause factors are an unstable waste market lack of management competencies and unstable macroeconomic conditions while the leading three effect factors are revealed as giving priority to other issues insufficient organisational structures and deviations in product quality. Although there are many studies on CE in cement they are concentrated on technical and laboratory studies enabling the use of different alternative materials as inputs to the cement process. Studying and revealing the barriers holding back the cement sector in the transition to CE is this study’s core contribution making it novel and unique. © 2023 Elsevier B.V.

The effect of the Internet of Things technology in reducing food waste and loss along the supply chain was examined by scanning the literature and conducting a 20-question survey including Yes/No, Open-Ended, and 5-point Likert Scale question types. It is an undeniable fact that companies attach importance to the idea of 'less food loss and waste' with their sensitive attitudes towards the use of natural resources, their investments to reduce the damage they cause to the environment throughout the supply chain, and their sustainable future goals. Although companies benefit from some Internet of Things applications to ensure food safety in certain processes of the supply chain, reduce or prevent food loss and waste in economic and social terms, to invest in an integrated Internet of Things technology that covers all processes and to make loss prevention or reduction processes more efficient, awareness studies should be carried out to companies and investment incentives should be provided by the state.Article Citation - WoS: 22Citation - Scopus: 34Analysis of barriers to circularity for agricultural cooperatives in the digitalization era(EMERALD GROUP PUBLISHING LTD, 2021-06-10) Erhan Ada; Muhittin Sagnak; Ruhan Askin Uzel; Irem Balcioglu; Uzel, Ruhan Askin; Balcioglu, Irem; Ada, Erhan; Sagnak, MuhittinPurpose This study aims to propose a novel framework for barriers to circularity within cooperative supply chains. The barriers in the adoption and implementation of circular economy principles are examined within a framework.

This study investigates the barriers to Sustainable Lean Supply Chain (SLSC) management within Small and Medium-Sized Enterprises (SMEs) and explores the structural interrelationships among these barriers. A comprehensive literature review was carried out to recognize critical elements relevant to the research topic resulting in the identification of fifteen specific elements that account for 85% of the barriers in SLSC management. The DEMATEL method was used to evaluate the significance and influence levels of these factors. Furthermore structured in-depth interviews were conducted with ten experts representing sectors that constitute 85% of the SMEs operating in Kayseri Organized Industrial Zone (OIZ) Turkey including metal products furniture plastic packaging construction materials textiles and food. The findings reveal that strategies represent the most significant barrier to SLSC management in SMEs. The barriers were analyzed in two dimensions: influencing and influenced factors. The primary influencing factor identified was laws standards regulations and legislation while the most significant influenced factor was found supply and suppliers. The study concludes with findings and actionable recommendations for practitioners and decision-makers.Doctoral Thesis Havalimanı operasyon yönetiminde net sıfır emisyonlu hidrojen çözümlerine geçiş: Airport örneği(2025) Sezer, Mürüvvet Deniz; Ada, Erhan; Kazançoğlu, YiğitHidrojene geçişin amacı, fosil yakıt bağımlılığını azaltarak daha sürdürülebilir, düşük karbonlu ve enerji güvenliği yüksek bir sistem geliştirmektir. Güneş enerjisi gibi yenilenebilir enerji kaynakları ile üretilen hidrojen, sürdürülebilir kalkınma hedefleri ile de doğrudan ilintilidir. Özellikle yenilenebilir kaynaklardan üretilen yeşil hidrojen sıfır karbon emisyonludur ve iklim değişikliğiyle mücadelede kritik öneme sahiptir. Ulaştırma sektörü gibi karbon yoğun sektörlerde hidrojen etkili bir çözümdür. Hidrojen üretimi, depolama, taşıma ve altyapı yatırımlarıyla yeşil kalkınmaya katkı sağlamaktadır. Ancak hidrojen sisteminin oluşturulmasındaki en önemli engellerinden biri yüksek yatırım maliyetleridir. Özellikle gelişmekte olan ülkelerde, yani geçişin daha ilk aşamasında olan ülkelerde, yeşil hidrojen üretimi, taşıma, depolama ve altyapı yatırımları oldukça pahalıdır ve hidrojen konusunda net politikalar, hedefler ve teşvik mekanizmaları eksik ya da yeni gelişmektedir. Bu kapsamda bu çalışmanın amacı havaalanı yer hizmetlerinde hidrojene geçiş için fayda maliyet analizini yapmaktır. Ayrıca bu çalışma hidrojene geçişte, sürdürülebilirliğin üç saç ayağının başarılmasını sağlamayı hedeflemektedir. Yeşil hidrojene geçişin ekonomik, sosyal ve çevresel etkileri analiz edilmiştir. Bu dönüşümün en önemli etkisinin çevresel boyut üzerinde olacağı düşünülse de uzun dönemde hem sosyal hem de ekonomik fayda sağlayacağı görülmüştür. Sonuçlara göre hidrojene geçişin önemli ölçüde yatırım maliyeti gerektirdiği yadsınamaz, fakat hidrojene geçişin uzun dönemde rekabet avantajı sağlayacağı ve özellikle karbon emisyon vergileri de dikkate alındığında karlı bir yatırım olduğu görülmüştür. Sonuçlar baz alınarak, hidrojen ekosisteminin önemli paydaşlarından olan endüstri ortakları, politika yapıcılar, yerel ve küresel otoriteler ve araştırma kurumlarının bu hedeflerinin başarılmasındaki rolü tartışılarak çeşitli öneriler geliştirilmiştir.
