- Abstract:
- Aiming at the difficulties of manual design and low degree of automation in modular building layout design, an intelligent layout design method for multistory modular buildings was proposed, which achieved efficient and automatic generation of diverse layout schemes. Firstly, automatic information extraction and building area grouping were carried out for modular architectural drawings, completing the conversion of initial twodimensional drawing information to standard information format. The layout schemes for multistory modular buildings were intelligently generated based on deep reinforcement learning. Through the synergistic effect of reward values such as the total number of module units, room adjustment values, and room adjustment quantities, the optimization and evaluation of module unit layout schemes were achieved. Finally, in order to enhance the practicality and operational convenience of the project, a modular intelligent building layout design platform was built by integrating functional modules such as building information extraction, building layout design, and layout scheme visualization. Taking the Lixinhu School project as study case, layout schemes were generated by using three preset specification module units in the proposed method. The total number of module units, room adjustment amount, room adjustment value, and normalized total indicator value for generating the plan were evaluated. The results show that the proposed method can efficiently generate module schemes suitable for different scenarios, improve the automation and intelligence level of modular building design, and provide technical support for engineering practice.
