Nadir Toprak Elementleri Seçimi İçin Kritik Kriterler Arasındaki İlişkilerin Analizi: DEMATEL Tabanlı Bir Yaklaşım

Öz

Nadir toprak elementlerinin (NTE’ler) güvenli ve sürdürülebilir tedariki, gelişmiş üretim, savunma sistemleri ve temiz enerji teknolojileri için hayati öneme sahip olmaları nedeniyle küresel ölçekte stratejik bir endişe konusudur. Ancak teknik, ekonomik ve çevresel faktörler arasındaki karmaşık ilişkiler nedeniyle, sanayi planlaması ve politika geliştirme süreçlerinde en önemli NTE’lerin seçimi zorlu bir konudur. Nadir toprak elementlerini seçerken dikkate alınan başlıca sekiz kriter; tedarik riski, üretici yoğunlaşması, ekonomik önem, fiyat dalgalanması, geri dönüşüm potansiyeli, çevresel ve sosyal etki, işleme zorluğu ve ikame potansiyelidir. Bu çalışmada, bu kriterler arasındaki ilişkileri incelemek için Karar Verme Deneyi ve Değerlendirme Laboratuvarı (DEMATEL) yöntemi kullanılmıştır. Bulgular, fiyat dalgalanması, geri dönüşüm potansiyeli, çevresel ve sosyal etki, işleme zorluğu ve ikame potansiyelinin esas olarak etki kriterleri olduğunu, tedarik riski, üretici yoğunlaşması ve ekonomik önemin ise sistemik dinamikleri yönlendiren ana neden faktörleri olduğunu göstermektedir. Bu sonuçlar, NTE tedarik zincirlerinin fiyat dalgalanmalarına ve tedarik kesintilerine karşı ne kadar kırılgan olduğunu ve geri dönüşüm ile ikame potansiyelinin giderek daha önemli hale geldiğini gösteren araştırmalarla uyumludur. Çalışma, seçim kriterlerinin hiyerarşik önemini vurgulayarak politika yapıcılara tedarik çeşitliliği, stratejik stoklama ve geri dönüşüm teknolojilerine yatırım gibi önlemleri önceliklendirme önerileri sunmakta ve kritik ham maddeler tartışmasına katkıda bulunmaktadır.

ANALYZING INTERRELATIONSHIPS AMONG CRITICAL CRITERIA FOR RARE EARTH ELEMENT SELECTION: A DEMATEL-BASED APPROACH

Abstract

The secure and sustainable supply of rare earth elements (REEs) is a global strategic concern since they are essential for sophisticated manufacturing, defense systems, and clean energy technologies. However, because of the intricate relationships between technical, economic, and environmental factors, choosing the most important REEs for industrial planning and policy is a challenging issue. Supply risk, producer concentration, economic importance, price volatility, recycling potential, environmental and social impact, processing difficulty, and substitution potential are the eight main criteria for choosing REEs. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) method is used in this study to examine the relationships between these criteria. The findings show that while price volatility, recycling potential, environmental and social impact, processing difficulty, and substitution potential are primarily effect criteria, supply risk, producer concentration, and economic importance are the main causal factors that drive systemic dynamics. These results are in line with research showing how vulnerable REE supply chains are to price shocks and supply interruptions, as well as how crucial recycling and substitution are becoming. By emphasizing the hierarchical importance of selection criteria and offering recommendations for policymakers to prioritize measures like supply diversity, strategic stockpiling, and investment in recycling technology, the study adds to the critical raw materials discourse.
