    Etkili hizmet tasarımı oluşturmada büyük veri analitiğinin etkisi
    (2023) Kaçar, Tuğçe Bilgiç; Ada, Erhan
    Competition between businesses is a system that has existed since ancient times. 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.

    Internet of Things Application in an Agricultural Food Supply Chain to Reduce Food Loss and Waste
    (2022) Sayar, Asya Gizem; Ada, Erhan
    In 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.

    Tarımsal kooperatiflerin gıda tedarik zincirleri bağlamında döngüsel ekonomi ve sürdürülebilirlik üzerine etkisi
    (2021) Balcıoğlu, İrem; Ada, Erhan
    Bu çalışma, tarımsal kooperatiflerin gıda tedarik zincirleri bağlamında döngüsel ekonomi ve sürdürülebilirlik üzerindeki etkisini incelemektedir. Tarımsal kooperatiflerin bu iki faktör üzerindeki etkisi, literatür taranarak ve anket çalışması yapılarak incelenmiştir. 14 tarım kooperatifi, 2 üretici birliği, 1 tarım kooperatifleri birliği ve su ürünleri kooperatifleri birliğinden katılımcılar ile yapılan Evet/Hayır, açık uçlu ve 5 puanlık Likert ölçekli soruların yer aldığı 25 soruluk anket çalışmasına göre; tarım kooperatifleri sürdürülebilirliğe ve döngüsel ekonomiye katkıda bulunmaktadır: ancak gelecekte katkı miktarını artırmak için daha fazla farkındalık, yeşil teknoloji kullanımı ve teşviklere ihtiyaç vardır. Bu kapsamda, bu konuların çözümüne yardımcı olması için bir Tarımsal Kooperatif Tedarik Zinciri Modeli önerilmiştir.
