Development of a smart design system

建筑过程工业化（模块化和非现场方法）的主要优点是环境友好型建筑过程，完工时间短，技术成本具有竞争力。Fortislight gauge steel（LGS）Structures Inc.专注于在工厂生产墙壁和浴室设备，然后将其运送到现场进行安装。由于他们的核心价值是减少现场施工时间，同时提高交付产品的质量，因此管理团队专注于减少工厂预制过程的周期时间，以提高生产力。然而，其在提高生产率方面的全部潜力尚未实现，因为制造过程中的劳动密集型任务涉及许多非增值活动，由于缺乏建筑和结构信息（即，在这方面，猜测和经验法则被科学和工程任务序列所取代，以提高生产率。因此，我们提出了一个综合的解决方案，它具有以下步骤：（1）识别问题，如缺乏设计信息或沉重的物理需求，这可能会导致生产率和安全性下降;（2）开发一个估算周期时间和效率评估的框架，以确定影响施工方法之间安全和生产率的相关因素（操作变量），任务序列（物理需求变量）和设计变量，如墙壁和开放空间的尺寸;开发了智能设计系统，通过优化工程方法确定墙板上的墙板和墙板的布置方式（例如登机表布局）和身体需求（例如最小姿势风险）因素。拟议的系统将最大限度地减少任务和材料利用的浪费（非增值活动）。智能设计系统预计将被实施，以提高生产力和安全的富通制造过程。

The primary advantages of industrialization of the construction process (modular and offsite method) are anenvironmentally-friendly construction process, short completion time, and cost-competitive technology. Fortislight gauge steel (LGS) Structures Inc. focuses on producing walls and bath units in their factory and then shipsthem to sites for installation. Since their core value is to reduce onsite construction time while improving thequality of the delivered product, the management team has focused on reducing the cycle time of theprefabrication process in the factory for better productivity. However, its full potential in terms of productivityimprovement has not yet been realized since labour-intensive tasks in the manufacturing process entail manynon-value added activities which its completion is heavily reliant on worker intuition and experience due to thelack of architectural and structural information (i.e., cutting patterns for boarding design) in the shop drawings.In this respect, the guesswork and rules of thumb are replaced with scientific and engineering sequences oftasks for productivity improvement. We thus propose an integrated solution which has the followingprocedures: (1) identification of issues such as lack of design information or heavy physical demands whichmay cause productivity and safety reduction; (2) development of a framework for estimating cycle time andefficiency evaluation to establish correlation factors which affects safety and productivity between constructionmethods (operational variables), sequences of tasks (physical demand variables), and design variables such asdimensions of walls and of opening space; and (3) development of a smart design system which determinessheathing and drywall sheet layout on wall panels by optimize engineering (e.g. boarding sheet layout) andphysical demand (e.g. minimum posture risk) factors. The proposed system will minimize wastes(non-value-adding activities) of tasks and material utilization. The smart design system is expected to beimplemented in order to improve productivity and safety of the Fortis manufacturing process.
