Process improvement model for prefabrication of panelized homes

预制房屋建筑已经成为房屋建筑商的一种流行的建筑方法，因为与之相关的是提高生产率、减少浪费和提高质量。该系统将建筑划分为墙、楼板和屋顶构件，这些构件在工厂中制造，然后运往现场并安装。考虑到小组讨论方法中的大多数活动都是在工厂环境中进行的，受控环境使其有可能极大地提高生产率。该系统具有很高的灵活性，因此可以根据项目要求定制墙板、楼板和屋顶板。然而，由于缺乏自动化生产控制系统，其在提高生产率方面的全部潜力尚未实现。因此，我们建议利用射频识别(RFID)系统、离散事件模拟(DES)和优化技术来开发预制板式家用生产设施的工艺改进模型。工艺改进模型将利用建筑信息建模来获取墙体、地板和屋面板信息，并通过模拟来优化生产工艺，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，并更新仿真模型的输入参数。作为这项研究的总体结果，工业化建筑领域有望通过集成基于模拟的优化和RFID系统在提高生产率和减少材料浪费方面受益。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，帮助建筑业走向板条化生产，从而降低生产成本和对环境的影响，并通过模拟优化为生产调度问题提供解决方案，将其惠及其他建筑行业。

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.
