(TAYLOR & FRANCIS LTD, 2024) Erhan Ada; Muhittin Sagnak; Sachin Kumar Mangla; Yigit Kazancoglu; Ada, Erhan; Sagnak, Muhittin; Mangla, Sachin Kumar; Kazancoglu, Yigit
Ecological pollution scarcity of resources climate change and population growth have forced organisations to transform from a linear to a circular economy. Hence the need arises to redesign value chains and traditional business models. Thus the aim of this study is to develop a new conceptual eco-cluster model called 'Circular Business Cluster Model' to combine the advantages of both clustering and a circular economy. This paper seeks to establish a framework and provide guidelines for policy-makers such as governments local authorities and organised industrial zone administrators. The contribution of this paper is to highlight and emphasise the crucial role of circular economy principles to transform a classical business model into an eco-business model. Circular Business Cluster Model includes the conceptual framework network structure interactions between cluster components and 6R activities. A case study was conducted to check the applicability of the proposed Circular Business Cluster Model. Eleven centres in this model were evaluated. Fuzzy Best-Worst Method (BWM) was used to find the relative weights. Based on the Circular Business Cluster Model theoretical and managerial implications have been presented.

Private public profit and non-profit organizations and society as a whole currently face a significant reliable information necessity problem. Especially supply chains need trustworthy information to perform their activities successfully. This study aims to propose a framework and identify how reliability of information can be evaluated and measured through the concept of transparency. In this context dimensions such as comprehensiveness regularity timeliness content scope and user-friendliness are the pillars of the proposed framework. Selected criteria have been used as inputs to develop the information transparency level. The fuzzy analytic network process (ANP) is used to obtain weights of these inputs and data envelopment analysis (DEA) is used for the determination of the efficiency ranking for transparency. Results demonstrated that content scope and comprehensiveness dimensions have 75% impact on the transparency of data. The remaining 25% is affected by timeliness regularity and user-friendliness.

(EMERALD GROUP PUBLISHING LTD, 2019) Muhittin Sagnak; Erhan Ada; Yigit Kazancoglu; Sagnak, Muhittin; Ada, Erhan; Kazancoglu, Yigit
Purpose Performance assessment of layouts requires a systematic approach because of its multi-objective nature. The purpose of this paper is to propose a framework to the performance assessment of layout designs. Design/methodology/approach A layout performance assessment framework is proposed grounded on a literature review. Then the causal relationships and prioritization of the sub-criteria are analyzed by fuzzy Decision Making Trial and Evaluation Laboratory technique in an elevator and escalator-manufacturing firm. Findings An integrated holistic performance assessment framework specifically the 7 criteria 19 sub-criteria and 112 measures are studied in this model which represents causal relationships and prioritization of sub-criteria. Research limitations/implications The proposed framework can be generalized because an integrative framework can be used in future empirical studies to analyze performance of layout design. However the causal relationships and prioritization among sub-criteria are analyzed based on the needs and capabilities of the individual company, therefore the results of the causal relationships are company specific. Practical implications With this framework the companies may assess their current layout's performance may analyze causal relationships and prioritization of sub-criteria. Originality/value There are very few models or frameworks regarding the performance assessment of layout designs. In this paper a new conceptual holistic framework was proposed as three-dimensional hierarchy which includes the main criteria sub-criteria and the measures respectively. Cost flow flexibility surrounding environment environment quality time and characteristics are identified as the main criteria for the layout design performance assessment. In addition cause-effect relationships which will be the base for improvement of the performance are found.

(2025) Sezer, Mürüvvet Deniz; Ada, Erhan; Kazançoğlu, Yiğit
Hidrojene 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.

In these days when the concepts of sustainability and circular economy are extremely prevalent the most critical issue to be addressed is food. Since food is a basic need circular economy practices have become extremely important especially in food packaging. Not only the robustness or minimization of the package but also the fact that the material used can be evaluated within the scope of circular economy ensures that food packaging is sustainable. Therefore the first aim is to investigate the impact of food packaging design on sustainability. Moreover to determine the relationship between circularity and food packaging design and to minimize the conflicting food packaging design characteristics against sustainability by circular design are other aims of this study. With this aim Quality Function Deployment method is applied for 29 consumer expectations about circular food packaging design (What's) and 34 technical requirements for these expectations for circular food packaging design (How's). The novelty of this study since food packaging design is a newly discussed topic it is important to consider the customer and technical expectations together in terms of circularity and sustainability. As a result the most important consumer expectations are determined and relationship is presented with technical requirements each other. It is expected that this study will be beneficial for managers and practitioners. © 2023 Elsevier B.V. All rights reserved.

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.
