LEAN PRINCIPLES FOR DETERMINING GENERATIVE DESIGN BENEFITS

Abstract

Studies on generative design have increased over the past decade, particularly for enhancing design processes in AEC industry projects. While generative design has shown potential benefits across various applications, its role in value generation remains unclear. This paper seeks to better understand the advantages of generative design through the lens of Lean principles and practices. A literature review and content analysis were conducted to map the different uses of generative design and their associated Lean principles. The review identified ten distinct uses of generative design, which were linked to nine Lean practices categorized under three Lean principles: value generation, flow improvement, and waste reduction. The results show that generative design is a versatile, interdisciplinary tool, applicable across planning, design, and construction phases. By aligning generative design with Lean principles, this study highlights its substantial contributions to improving flow, generating value, and reducing waste in construction projects. However, the findings also reveal a lack of integration across systems and processes, with applications often focused on isolated project stages or disciplines. This fragmentation suggests a tendency toward local optimization, highlighting the need for future research on system-wide integration to fully align generative design with Lean principles.
