Reducing rework and optimizing productivity in a fabrication and modularization environment

在制造和模块化环境中降低返工风险并优化生产率可以为Aecon等工业和商业建筑商节省高达20%的制造和建筑劳动力成本。仅在加拿大，整个行业每年就可节省数亿美元，这将提高Aecon等公司在该行业的国际竞争力。要做到这一点，从而第一时间以最好的方式做好工作，需要训练有素的人员、有效的信息传递、适当的工具、正确的材料和仔细的规划。我们建议通过进一步开发申请人最近开发的创新3D成像和分析算法的组合来改善信息传递、反馈和规划。这些进一步的发展将与新兴的增强现实工具相结合，以提高效率。我们将首先专注于工业建筑项目的预制工作，包括管道，导管和钢组件的3D设计，并由熟练的工匠在商店中制造，他们拥有先进的切割，装配和焊接设备，并得到包括无线通信，平板电脑和集成系统在内的信息技术基础设施的支持。焊工将拥有一个强大的工具，作为研究的结果，它将自动将正在进行的工作的3D扫描与平板电脑上工作的3D设计重叠，以指导他的下一步，帮助他避免装配和焊接中的错误，检查公差，并自动规划最佳对准程序。还将探索将平板电脑摄像头的视角纳入其中的扩展。这项研究将促进加拿大制造商竞争力的一步变化。

Reducing rework risk and optimizing productivity in a fabrication and modularization environment could save industrial and commercial constructors such as Aecon up to 20% of their fabrication and construction labour costs. Resulting savings could reach hundreds of millions of dollars per year across the industry in Canada alone, and it would enhance the international competitiveness of companies in this industry such as Aecon. Doing this, and thereby doing work right the first time and in the best way requires well trained people, effective delivery of information, proper tools, correct materials and careful planning. We propose to improve information delivery, feedback and planning by further developing a combination of innovative 3D imaging and analysis algorithms recently developed by the applicants. These further developments will be integrated with emerging augmented reality tools to enhance effectiveness. We will focus first on prefabrication work for industrial construction projects that is comprised of piping, conduit and steel assemblies designed in 3D and fabricated in shops by skilled trades-people with advanced cutting, fitting and welding equipment supported by an information technology infrastructure that includes wireless communications, tablet computers and integrated systems. A welder will have a powerful tool as a result of the research that will automatically overlay 3D scans of a work in progress with the 3D design of the work on his tablet computer in a way that will guide his next steps, help him avoid errors in fit-up and welding, check tolerances, and automatically plan optimal alignment procedures. Extensions to incorporate the perspective of the tablet's camera as well will also be explored. A step change in Canadian fabricators' competitiveness will be facilitated by this research.
