Prioritizing Critical Success Factors for Wind Turbine Suppliers: a Neutrosophic Hybrid Dematel and Anp Approach

Abstract

The global energy landscape is experiencing a transformative shift toward sustainability, with wind energy becoming an indispensable clean energy source crucial for combating climate change. As the number of wind turbine suppliers increases, stakeholders face significant challenges in selecting the most suitable partners, which can directly impact project outcomes and overall efficiency. This study aims to systematically identify and prioritize the critical success factors for wind turbine suppliers, facilitating effective decision-making in supplier selection. To achieve this, we present an innovative hybrid Decision Making Experiment and Evaluation Laboratory Method and Analytic Network Process framework, enhanced by a neutrosophic fuzzy environment. Our findings reveal that key factors such as component price (C1) with a weight of 0.055, operation and maintenance cost (C3) with 0.049, and annual energy production (C5) with 0.042 play significant roles in the decision-making process. Among these, component price (C1) is the most critical factor, indicating that cost considerations are paramount in the decision-making process. Notably, the findings emphasize the importance of optimizing supplier relationships, particularly in terms of service quality and technical competence, to ensure successful project implementation and long-term sustainability in the rapidly evolving renewable energy market. This study provides essential insights for both academic research and industry practice. Academically, it fills a critical gap in the literature on wind energy supplier selection by presenting a novel methodology that can guide future research. Practically, it equips industry stakeholders with actionable data to optimize supplier relationships, ultimately enhancing project outcomes and long-term sustainability. These findings are particularly relevant for stakeholders in emerging markets, where cost management and supplier selection are critical to project viability. By optimizing supplier selection, this study contributes to the broader goal of achieving sustainability in renewable energy projects.
