A Hybrid Fuzzy MCDM Methodology for Optimal Structural System Selection Compatible with Sustainable Materials in Mass-Housing Projects

The present paper aimed to propose a new support approach choosing the optimal structural system in accordance with sustainable materials mass-housing projects. To this end, an integrated fuzzy multi-criteria-decision-making (fuzzy MCDM) method was used identify criteria affecting material selection. proposed consists of three-phase protocol: In phase I, literature create database encompassing 42 factors selection materials. These were classified as four indicators (economic, environmental, socio-cultural, technical-executive) development aspects. II, Delphi (FDM) screen key factors. III, SWARA–ARAS prioritize for case project: evidence from Iran. results selecting systems based on 14 efficient showed that Light Steel Frame (LSF), Insulation Concrete framework (ICF), and Prefabricated Reinforced System (PRC) have highest priority achieve goals selection, respectively.
