Article Barriers in Sustainable Lean Supply Chain Management: Implementation in SMEs(EGE UNIV FAC ECONOMICS & ADMIN SCIENCES, 2025) Ebru Takci; Erhan Ada; Yigit Kazancoglu; Takci, Ebru; Ada, Erhan; Kazancoglu, YigitAs the world undergoes significant transformations in various domains including technology energy supply and communication the idea of sustainability has become a significant issue. 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.Master Thesis Internet of Things Application in an Agricultural Food Supply Chain to Reduce Food Loss and Waste(2022) Sayar, Asya Gizem; Ada, ErhanIn this study, in order to prevent or reduce food loss and waste throughout the food supply chain, it has been examined to what extent corporate companies that produce and export perishable agricultural products benefit from the Internet of Things technology in their operational activities and whether they will include such applications in their future investment plans. 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.Conference Object Quality Function Deployment to Improve Beverage Packaging Design and Sustainability(Springer Science and Business Media Deutschland GmbH, 2023) Erhan Ada; Muruvvet Deniz Sezer; Serhat Aksoy; Ergin Ulunay; Aksoy, Serhat; Sezer, Muruvvet Deniz; Ulunay, Ergin; Ada, Erhan; N.M.

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.Article Citation - WoS: 10Citation - Scopus: 11The financial impacts of information systems security breaches on publicly traded companies: reactions of different sectors(Emerald Group Holdings Ltd., 2022) Cansu Tayaksi; Erhan Ada; Yigit Kazancoglu; Muhittin Saǧnak; Tayaksi, Cansu; Ada, Erhan; Kazancoglu, Yigit; Sagnak, MuhittinPurpose: Today information systems and technology provides a wide set of tools for companies to increase the efficiency of their businesses. Although technology offers many benefits to businesses it also brings risks as the information systems security breaches. Security breaches and their financial impact is a constant concern of the researchers and practitioners. This paper explores information systems breaches and their financial impacts on the publicly traded companies in different sectors. Design/methodology/approach: After a comprehensive data collection process data from 192 events are analyzed by employing Event Study Methodology and a comparison of the results between the four highly affected sectors (Consumer Goods Technology Financial and Communications) is presented. The abnormal returns on the prices of stocks after the events are calculated with the Market Model. Also the results of the Market Adjusted Model and Mean Adjusted Model are presented to support the results. Findings: While information systems security breaches have a significant negative impact on the Financials and the Technology sectors for all the event windows in the study ([−5 0] [−5 1] [−5 5] and [−5 10]) the significant negative impact is observed only on the [−5 5] and [−5 10] event windows for the Consumer Goods sector. No significant negative impact is observed in the Communications sector in fact the cumulative abnormal returns are positive for this sector. Originality/value: The contribution of this paper to provide evidence about the financial impacts of the information systems breaches for businesses in different sectors. While there are studies that have previously focused on the information systems breaches and their financial impacts on businesses to the best of our knowledge this is the first study that compares this effect between the four highly impacted sectors. With a relatively larger sample size and broader event windows than the past studies in the literature statistical evidence is provided to managers to justify their investments in information security and build preventive measures to secure the market value of their firms. © 2022 Elsevier B.V.

Within the framework of this purpose, an in-depth literature review was carried out at the stage of determining the elements constituting the subject of the research. As a result of the literature review, 15 concrete elements that constitute 85% of the barriers in Sustainable Lean Supply Chain (SLSC) Management were obtained. The DEMATEL method was used to examine the importance and impact level of the obtained elements. In this direction, the companies working on sustainability in Kayseri and sector-based clustering of ISO first and second 500 companies operating in Kayseri in 2022 was carried out and senior executives working on sustainability were asked to compare 15 barriers in pairs. The findings show that among the barriers in Sustainable Lean Supply Chain (SLSC) Management in SMEs, strategies are at the highest level. In addition, the barriers in Sustainable Lean Supply Chain (SLSC) Management in SMEs are examined in two ways as affecting and affected. It has been determined that Laws/Standards/Regulations/Legislation are the most important influencing factor. It has been determined that the most important factor affected for SMEs is supply/suppliers. As a result of the findings obtained within the scope of the research, various suggestions have been developed for the relevant literature and practitioners.

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.

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: 22Citation - Scopus: 34Analysis of barriers to circularity for agricultural cooperatives in the digitalization era(EMERALD GROUP PUBLISHING LTD, 2022) 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. Design/methodology/approach Fuzzy best-worst method is used to calculate the weights of barriers and identify the prioritization of barriers to circularity within cooperative supply chain. Findings Insufficient implementation of circular economy laws was found as the most important barrier followed by Lack of information Ineffective recycling policies Lack of awareness for circular economy Remanufacturing is a labor-intensive procedure Inconsistent price policies in sources and products Lack of environmental management system Cost of implementation for green activities and Lack of R&D capability barriers respectively. Research limitations/implications The number of participant professionals limits the conclusions of the study and reaching more general conclusions. A comprehensive research can be conducted by the participation of a greater number of professionals. Originality/value Several studies analyzed the barriers to circularity, however to the best of the authors' knowledge no study has been taken an approach for barriers to circularity for cooperatives or cooperative supply chains.Review Cloud Manufacturing: A New Cloud Computing Model in Operations Management(EGE UNIV FAC ECONOMICS & ADMIN SCIENCES, 2016) Cansu Tayaksi; Erhan Ada; Yigit Kazancoglu; Tayaksi, Cansu; Ada, Erhan; Kazancoglu, YigitTogether with information and communications technology the concept of management and business conducting has been changing.
