Abstract: (246 Views)
Introduction: The rapid development of modern societies has intensified the demand for high-quality luxury residential buildings, which play a pivotal role in enhancing living standards. However, translating customer expectations into engineering requirements during design, construction, and operation remains a critical challenge. This study addresses this gap by proposing a novel model to improve quality management in luxury residential construction. Utilizing fuzzy logic and a two-stage Quality Function Deployment (QFD) approach, the research evaluates customer-defined quality criteria and prioritizes enhancement strategies. The findings reveal a significant shift in the perception of "luxury" in real estate, emphasizing quality as a central factor.
Methodology: This study employs a mixed-methods approach, combining qualitative and quantitative techniques. Data were collected through expert interviews, surveys, and fuzzy pairwise questionnaires, analyzed using fuzzy Analytic Hierarchy Process (FAHP) and Best-Worst Method (BWM). The two-stage fuzzy QFD framework was applied to translate customer needs (e.g., durability, aesthetic appeal) into technical specifications (e.g., BIM adoption, cost-time management). Software tools such as Atlas.ti, Excel, and LINGO were used for data processing. The House of Quality (HOQ) matrix structured the relationship between customer requirements and quality enhancement measures.
Results: The study identified 12 key quality management criteria, with "time and cost management" (weight: 0.1035), "BIM implementation" (0.1029), and "operational management" (0.0991) as the top priorities. Five dimensions of luxury—functional, comfort, economic, social, and environmental—were validated as critical to quality. The proposed model integrates 16 initial requirements (e.g., sustainable design, material quality) into a structured framework, emphasizing stakeholder alignment and continuous improvement. Fuzzy QFD analysis demonstrated that addressing ambiguities in customer feedback enhances decision-making precision.
Discussion: The results underscore the transformative potential of integrating fuzzy QFD and BIM in luxury construction. Effective time-cost management mitigates project delays and budget overruns, while BIM adoption reduces design-execution discrepancies. Operational management ensures long-term quality post-construction. The study highlights the need for risk-adjusted budgeting and earned value management to sustain quality. Limitations include reliance on expert opinions, suggesting future research should validate the model across diverse projects. This work contributes a scalable framework for aligning luxury construction with evolving customer expectations and industry standards.
