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.

施工过程的工业化(模块化和异地方法)的主要优势是对环境友好的施工过程，完成时间短，以及具有成本竞争力的技术。Fortislight Gauge Steel(LGS)Structures Inc.专注于在其工厂生产墙体和浴缸单元，然后将其运往现场进行安装。由于它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缩短工厂预制过程的周期时间，以提高生产率。然而，它在提高生产率方面的潜力尚未完全实现，因为制造过程中的劳动密集型任务涉及许多非增值活动，由于车间图纸中缺乏建筑和结构信息(即木板设计的裁剪图案)，这些活动的完成严重依赖工人的直觉和经验。在这方面，猜测和经验法则被用于提高生产率的任务的科学和工程序列所取代。因此，我们提出了一个集成的解决方案，它包括以下步骤：(1)识别可能导致生产率和安全性降低的设计信息缺乏或繁重的物理需求等问题；(2)开发一个估计周期时间和效率评估的框架，以建立施工方法(操作变量)、任务顺序(物理需求变量)和设计变量(如墙体尺寸和开敞空间的尺寸)之间影响安全性和生产率的相关因素；以及(3)开发一个智能设计系统，通过优化工程因素(例如登机板布局)和物理需求(例如最小姿势风险)因素来确定墙板上的护套和干墙板布局。拟议的系统将最大限度地减少对任务和材料利用的浪费(非增值活动)。预计将实施智能设计系统，以提高富通制造过程的生产率和安全性。
