계층화 분석을 이용한 공공건축물의 순환골재 활용 활성화 요인 분석

초록

This study employed the analytic hierarchy process (AHP) to investigate the main decision-making factors involved in the selection of materials forrecycled aggregates for constructing public buildings. The factors, which consisted of five main items and 15 detailed items in the AHP model, were devised through consultations with construction experts. Based on the weights of the main and detailed items, the “Subject to mandatory use” element exhibited the highest level of importance, followed by the “supplier” and “price” elements in the procurement sector, and the “specification content” in the construction sector. Furthermore, the results revealed that it is essential to reflect the use of recycled aggregates at the initial design stage and to introduce a mandatory use of recycled aggregates. In addition, the criteria for suppliers to meet upgrading the production technology of recycled aggregates are required.
