제너레이티브 디자인 기반 DfMA 설계 지원을 위한 건축 구성재 조합 알고리즘 개발 및 적용에 관한 연구

The AEC industry faces persistent challenges such as an aging workforce and low productivity. Off-Site Construction (OSC) and Design forManufacture and Assembly (DfMA) are emerging as solutions to these issues, receiving significant attention and application in the UnitedStates, Singapore, Hong Kong, and recently in Korea. DfMA, a design method that incorporates front loading at the design stage, involvesanalyzing and disassembling all aspects of a building to design modules optimized for transport and installation. Recognized for its potentialto enhance safety, reduce construction time, and increase productivity, DfMA addresses the limitations of OSC construction, particularly errorsin the complex design and fabrication stages. To enhance OSC's effectiveness and productivity, this study proposes the development of aBIM-based generative design algorithm. This algorithm aims to rapidly generate numerous combinations of building components usingdomestic OSC materials, applying DfMA principles at the design stage. The research methodology includes a review of DfMA concepts,analysis of case studies and prior research, investigation and classification of domestic OSC building components, and development of agenerative design algorithm for building component combinations. By applying this algorithm, the study seeks to identify and verify theoptimal combination of components, considering budget and selected types. Despite DfMA's advantages, issues such as design complexity,uniformity, and assembly errors have been extensively studied. The algorithm introduced in this research could contribute significantly toDfMA-based architectural design, improving fabrication and assembly efficiency early in the design process.
