A BIBLIOMETRIC ANALYSIS OF RESEARCH TREND ON KNOWLEDGE AND APPLICATION OF THE LIFE CYCLE COSTING

Abstract

This study examines the growing trend of applying Life Cycle Costing (LCC) in academic research, a crucial methodology for assessing the long-term economic viability of products, projects, and systems, particularly in the domains of sustainability and construction. Despite the growing relevance of LCC in supporting cost-effective and sustainable decision-making, a comprehensive analysis of how this concept has been adopted and developed within the scholarly literature remains lacking. To address this gap, a bibliometric analysis was conducted using data retrieved from the Scopus database, focusing on documents published up to the early part of 2025. A total of 970 relevant records were identified and analyzed using Scopus Analyzer and VOSviewer software to evaluate publication trends, citation patterns, keyword co-occurrences, and international collaboration networks. The results indicate a steady increase in publications over the past decade, with notable contributions from countries such as the United States, China, the United Kingdom, and Australia. Key research themes include sustainable construction, cost-benefit analysis, circular economy, and decision-making models. Collaboration patterns reveal that countries with higher citation impact tend to have stronger international linkages, suggesting the importance of global cooperation in advancing LCC research. This analysis highlights the growing interest in LCC and the shifting focus toward integrating economic evaluation with environmental and social dimensions. The study concludes that LCC is transitioning from a niche financial tool to a strategic framework for sustainable planning and policymaking and recommends increased interdisciplinary and cross-border collaboration to enrich the field further.
