Process improvement model for prefabrication of panelized homes

预制房屋建筑已成为房屋建筑商中流行的建筑方法，由于相关的提高生产率，减少浪费和提高质量。该系统将建筑物分为墙壁，地板和屋顶元素，这些元素在工厂中制造，然后运送到现场并安装。鉴于小组化方法中的大多数活动都是在工厂环境中进行的，受控环境使得可以大大提高生产力。该系统提供了高度的灵活性，因此可以根据项目要求定制墙壁，地板和屋顶面板。然而，由于缺乏自动化生产控制系统，其在提高生产力方面的全部潜力尚未实现。因此，我们建议开发一个过程改进模型，预制板的家庭生产设施，利用射频识别（RFID）系统，离散事件仿真（DES）和优化技术。过程改进模型将利用建筑信息建模来获取墙壁、地板和屋顶面板信息，并使用模拟来优化生产过程，以减少材料浪费和生产时间。该模型还将使用RFID提供实时定位系统并更新仿真模型输入参数。作为这项研究的一般结果，工业化建筑领域预计将受益于提高生产率和减少材料浪费方面，通过集成的基于仿真的优化和RFID系统。拟议的研究将通过简化流程来降低生产成本，这可以通过应用仿真，优化和RFID技术来实现。它还将通过提供有效的生产工具来帮助建筑行业走向面板化生产，这将降低生产成本和环境影响，并通过基于模拟的优化提供生产调度问题的解决方案，将其利益扩展到其他建筑行业。

Prefabricated home building has become a popular construction method among home builders due to the associated improved productivity, reduced waste, and increased quality. This system divides a building into wall, floor, and roof elements, which are manufactured in a plant and then shipped to site and installed. Given that the majority of activities in the panelized approach are performed in a factory setting, the controlled environment makes it possible to greatly improve productivity. This system provides a high level of flexibility, such that wall, floor, and roof panels can be custom-manufactured based on the project requirements. However, its full potential in terms of productivity improvement has not yet been realized due to the absence of an automated production control system. We thus propose to develop a process improvement model for prefabricated panelized home production facilities utilizing a radio frequency identification (RFID) system, discrete-event simulation (DES), and optimization technologies. The process improvement model will utilize building information modelling to obtain wall, floor, and roof panel information and optimize the production process using simulation to reduce material waste and production time. The model will also use RFID to provide a real-time location system and update the simulation model input parameters. As a general result of this research, the industrialized construction domain is expected to benefit in terms of improved productivity and reduced material waste through integrated simulation-based optimization and RFID system. The proposed research will reduce production cost by streamlining the process, which can be achieved by applying simulation, optimization, and RFID technology. It will also help the construction industry to move towards panelized production by providing effective production tools which will reduce production cost and environmental impact and will extend its benefit towards other construction sectors by providing a solution to the production scheduling problem through simulation-based optimization.
