Cross-phase product configurator for modular buildings using kit-of-parts

Abstract

One emerging strategy in industrialized construction is the use of mass customization to increase product efficiency without sacrificing design flexibility. Effective implementation of mass customization can be done through a product platform, i.e. a configurator. However, existing configurators often lack integration of knowledge from the downstream supply chain such as manufacturing. This paper proposes a conceptual framework for a configurator unified through a manufacturing kit-of-parts. Kit-of-parts are pre-engineered and pre-designed digital models representing fabrication-ready components. Using production rules and restraints, accurate planning and design representations can be derived and utilized in the configurator. This research develops a configurator prototype using three-tier architecture. The prototype supports a low-to-high level of detail of kit-of-parts. It integrates product platforms and project development across multiple building phases including site planning, floor plan layout, and 3D model generation. Finally, the implementation of a modular building configurator illustrates the benefits of the proposed configurator-based workflow.
