    Purpose Sustainable supply chain management (SSCM) practices and policies are necessary for businesses that seek to take part in international markets and ensure any form of competitiveness. Over time, and especially in the recent past, researchers, governments, and other policymakers have made use of broad and systematic approaches and come to appreciate the value-enhancing activities of sustainability. Design/methodology/approach Businesses have embraced the integration of sustainable policies and practices within the supply chain as a critical step in ensuring the efficiency of their operations. It is clear in previous studies and operational programs of enterprises that SSCM practices accord businesses certain benefits including improving their environmental, social, and economic performance, and increasing their ecological awareness by way of influencing performance elements within supply networks in enterprises. The study examines the factors influencing performance and theories of SSCM using a neutrosophic method in the textile industry. Findings SSCM performance is thus of great importance in ensuring business success and competitiveness, realizing customer satisfaction, and leaving the environment in a desirable state for future generations. Performance management, by assisting in the decision-making by managers and ensuring an adequate level of internal interaction, is an integral part of assimilating sustainability management into businesses. SSCM theories also have a strong impact on the determination of the sources of competitive advantage through effective utilization of business capabilities to solve environmental and social challenges that may affect business performance. Originality/value In line with the benefits highlighted, this study seeks to evaluate and select the factors affecting SSCM performance and theory in textile enterprises with corporate identity in Ordu and Giresun provinces following a neutrosophic approach. To this end, the elements obtained from the literature review are evaluated using the MULTIMOORA-mGqNN method.

    Analysing Mobile Banking Quality Factors from Neutrosophic Set Perspective: A Case of Study of Turkey
    (Journal of Economics, Finance and Accounting, 2017) Basil Oluoch Okoth; Serpil Altinirmak; Mustafa Ergun; Caglar Karamasa
    Purpose - Mobile banking, also known as m-banking, provides low cost, innovative and easily accessible services to customers with technological developments as compared to retail banking. In this context, m-banking quality factors of the banks are considered to be important issues for customers. The aim of this study is to analyze the m-banking quality factors and to rank banks offering this service in Turkey under incomplete, inconsistent and indeterminate information. Methodology - First linguistic expressions of experts are converted to crisp values via approximation approach proposed by Chen and Hwang. Then, the Single Valued Neutrosophic Set (SVNS) based entropy, which deals with incomplete, indeterminate and inconsistent environment better than fuzzy set, is used to rank the banks providing m-banking services in Turkey. Findings- Findings - show that the Denizbank has the best performance in m-banking applications followed by TEB and ING. Additionally, in terms of entropy weights, response time was found to be the most important criterion followed by accessibility, accuracy and trust. Conclusion- Banks could consider the criteria of response time, accessibility, accuracy and trust for improving the performance in mbanking services implementation.

    Critical Success Factors of Lean Six Sigma to select the Most Ideal Critical Business Process Using q-ROF CRITIC-ARAS Technique: Case Study of Food Business
    (Science Direct, 2023-08-15) Basil Oluoch Okoth; Ahmet Aytekin; Selçuk Korucuk; Arunodaya Raj Mishra; Salih Memiş; Caglar Karamasa; Erfan Babaee Tirkolaee
    The current market conditions have forced Lean Six Sigma (LSS) upon businesses as one of the must-have practices. The practices have been credited with enhancing the efficiency of the operational and functional processes of enterprises from production to marketing, from personnel management to finance, all the while helping them augment their growth and profitability. LSS has the customer as its main focus and works to create added value for businesses through cost reduction and waste prevention hence can be considered as a process improvement practice. One priority area of improvement in most organizations is the assessment of Critical Business Processes (CBPs) as key processes in the success of businesses that must be tackled in line with the objectives of the businesses due to their extensive impact on customer satisfaction. For this purpose, this study evaluates and ranks the CBPs, and then select the most ideal CBP in food companies with corporate identity in Istanbul following the LSS success factors. Hence, the components attained from the literature are assessed using the suggested “q-ROF CRITIC-ARAS” method which is based on CRiteria Importance Through Intercriteria Correlation (CRITIC), Additive Ratio Assessment (ARAS) techniques and q-Rung Orthopair Fuzzy Sets (q-ROFSs). The findings demonstrate that the most important criterion for LSS success in food businesses is “Top Management and Support”, while “Education and Culture” is the least important. Furthermore, “Enlightenment Approach” is found to be the most ideal CBP based on LSS success factors.

    Examining the Critical Success Factors Related to Enterprise Resource Planning: A Case Study in Ordu Province
    (2023-06-29) Basil Oluoch Okoth; Selcuk Korucuk; Ezgi Demir; Sule Bayazit Bedirhanoglu; Caglar Karamasa
    Enterprise Resource Planning (ERP) and success factors are systems that enable effective and efficient management of businesses by facilitating coordination and interaction among different units. Therefore, the decision to select the right and applicable ERP implementation and success factors for businesses is a crucial matter. However, due to the cost of ERP implementations and the lengthy adaptation periods for businesses, selecting the relevant systems and success factors requires careful consideration. Identifying ERP implementations and success factors that are suitable for the business processes and structure of the company is a significant decision-making problem, which can be considered as a gap in the literature. In this regard, this study used the Neutrosophic Decision Making Trial and Evaluation Laboratory (DEMATEL) method to analyze the critical success factors for ERP in production companies that had more than 10 employees. The results show that project management and top management support were the most important factors. The results have significant implications for business managers and stakeholders involved in the subject matter in terms of cost and resource efficiency as well as gaining competitive advantage
